Title: 1985 CR500RF Rebuild
Post by: Hoony on January 13, 2008, 11:59:26 am
this has been a slow resto over 2 years. part one was a cosmetic tidy up and safety rebuild as it was missing spacers in the swingarm and rear wheel, so i pulled everything down except motor ready for my first viper season  on this bike (2006) as i rode the prevoius seasons on my 250. i never owned a 500 when i was racing seriously (pre VMX days) and as i am going though a mid life crisis it was time to tick something off the list.

Heres a pic of the bike when i got it back in Jan 2006, it was used as a trail bike (could not think of a worse bike in the bush) the guy who bought it wanted a bike so he could ride with his kids, he said i used to ride big bikes years ago so it will be fine, he rode it once and then put it back in the dealers to sell for him and bought a 250cc fourstroke trailbike.

it was rough but fairly original but had signs of bush mechanics.

heres a few pics of a hacked up airbox and dodgy work to the pipe. why anyone would have an airbox like this beats me, have a look at the nice sweeps on the tailpipe.

the sub frame had also been butchered for the pipe as you can see.

Hey Hoony there is some nice welds on that pipe and frame . It looks like he was trying to choke some life out of the beast so he could ride it .
Title: Re: 1985 CR500RF Rebuild
Post by: Hoony on January 13, 2008, 12:15:43 pm
the frame was badly mashed in and cracked but as i wanted to ride it this had to wait till now as i have aquired all i need to finish the job properly, i did of course fix the pipe, airbox and sub frame for 06-07 seasons, now it is time to complete the rest of the resto.

Great to see the big 5hundy Hoony, and its about time too ;) ;D.  That airbox, what are you going to do to fix it or will you look around for a better one?
I know pro-circuit do a pipe for this bike and it look BIG and Mean. Its like a snake the way it twists around the bike.Venomous

ok this brings us up to race ready for season 2006, a tidy up and repair of all dodgy works and ready to try the bike out and work out if it need a engine rebuild or not for this season. the frame and extras will be done at a later date in part 2 of the resto which i will post later.

Post by: Hoony on January 13, 2008, 12:36:13 pm
later model (1986 CR500RG) frame has a fewmods from prevoius model as follows

stronger engine mounts, different footpeg mounts and pegs, different coil and CDI mounts (CDI & coil are totally different, 85' is similar to the 84' RE model) a small lug to protect the rear brake torque arm, different sub frame mount at the top.

i got this 86' frame on ebay and it was low hours, the 85' frame was too far gone as the engine mounts and crushed frame railes and lots of dodgy work swayed me to a replacement rather than a repair. i had to cut off the CDI & coil mounts and made mounts to fit the 85' model CDI & coil.

here is a pic of the original CDI & coil mounts for the 86' Frame.

send me some more Andrew. it looks fairly original, i got mine for $2k, i reckon that was a bargain so if you get it anywhere around $2.5k thats a good price. beware the dreaded water pump housing for corrosion and give it a good once over.

he wants $3G for it....the owner said it doesnt need a cent to be spent on it....but whats sorta put me off it are the cracks....yes cracks in the frame same spot as yours anderneath the motor...he says he has welded them up but it dont look good...cause its been sprayed with some sort of black paint....my 84 model had the same problem but it wasnt as bad as yours in those pics earlier on you put up....heres another pic....have a close look at the bottom frame rails....

Post by: Hoony on January 13, 2008, 07:48:20 pm
if he reckons that it needs no money spent on it well that is only his opinon, its different when You buy it of course as everyones standards are different (you may want new tyres, chain & spockets, Bars, etc)

$3k is not shit loads for a big bore 2 stroke from this era if its as good as what he says. i would suggest go right over it and check as much as you can out. even if you found one that was rough but resonable it can cost you way more in $ and time once you start to restore them. so if its a real good one i would pay that. if frame is done well (i can't tell from the pics) it should be ok, mine was too far gone in a few area's to warrant repair and i saw the 86' frame and got it at a better price than i could of repaired mine for. of course haggle him down a bit if you can.

 just noticed that something (other than the color) is not right with the seat ?

 hoony yes the seat cover isnt standard and the foam thats up against the tank looks out of place....where did you get your 86 model frame  from...cause i think i might know where there is one cheap one a long time ago... and have they got the same specs ..eg ..does the motor slip straight from an 85 model in the 86.... oh and also whats your view on why the 500s frames always crack under the frame rails...it seems to be a common occurance on these...

you may be right Brad, i have not got the bike fully assembled yet, pic i posted early is with the 85' frame (taken at start of 2006).

i have the 86' with the front end in it only at this stage, more follow up to come on this thread

Bugger, just got some shed time in after knocking off work early today. i made up my centre case gasket and thought i would check my gearbox clusters out before reassembly of bottom end and realised that 1 gear box thrust washer is wrong size and one is missing (the bike shifted fine before i pulled it down) either i have lost a washer or it never had one. another order placed to honda and hopefully i will get it tomorrow arvo.

Nothing like a 'thorough' rebuild hey hoony.  You start on one thing, an notice another and another and on it goes.

yep , thats the way its been mate. i also should have been a bit more organised and went over everything in one hit rather than wait for parts then check next item etc, as everytime i check something it needs work, but then again i am also a fussy prick.

Post by: evo550 on January 19, 2008, 09:50:50 am
Hooney,
Rebuilds on pre'85/90 bikes are a nightmare too many wearing bits. I've done my first and last one.
If i get the inclination to buy another one, it'll be a low hours/highly maintained expensive one, cheap "Project" ones are a bottomless pit.
On a positive note at least it doesn't have a power valve........that'd be flogged for sure.
It'll all be worth it when you get it onto some green rolling hills with long straights and wide sweeping turns, with soil like plasticine.

Post by: 090 on January 19, 2008, 09:56:34 am
I will be doing a resto on a 85 500 at some stage. But its down the list a bit as it will be a NOS type of do up just to look at as a reminder of my youth ( before i get to old to remember! ). A friend found a second one for sale a couple of months ago on the side of the road,i couldn't give him the money quick enough! Those deals when you cant give the guy the money quick enough, i love those deals as it usually means a good deal! I have a heap of NOS sorted already, all the hard stuff. I beat you to the last set of shrouds too Hoony! Sitting in the dead stock list on the north QLD coast,do you hate me now (rub, rub)
Title: Re: 1985 CR500RF Rebuild
Post by: Hoony on January 19, 2008, 11:42:57 am
Evo, you got it in one mate, (what did you restore ?) and i agree about the power valves too as i restored an 86' 250 and that took some time. lots of time just going over the linkage rear ends, cleaning, greasing etc. Yes i do enjoy riding the 500 on the tracks that are fast and sweeping, but to be quite honest i reckon my lap times are probably much faster on a 250 than a 500, but to me i don't care as the 500 has the adrenaline factor and i no longer chase trophies, i just want to ride these days.

Brad, yep i have been chasing that elusive RHS Radiator shroud for over 18mths now, i managed to get a LHS but missed out from CMNSL by who else but Magoo would you believe. now Brad what if i Name my next child due in April after you, can i get that shroud  ;D

i thought i had one coming ex USA but it was listed as ex stock incorrectly. my best hope is if one of our US forum members can do a NOS search at a dealer for me.

yer id like to know the same thing....does the the water pump corrode like the cr250re that ive always been hearing about....
Title: Re: 1985 CR500RF Rebuild
Post by: Hoony on January 21, 2008, 08:09:33 pm
actually it was this good when i got it, where everything else was stuffed. it did have a leak wednesday before CD4 and that sent me into panic mode but a devcon number fixed that.

i have only had to repair my Cr's 3-4 times in 20+ years. the worst was when i had a motor on the bench for a whole year and then some before i pulled it down, it was very badly corroded. i reckon if you don't flush the case out and the air gets to itthey will corrode fast and badly. i don't bother to drain mine when not in use and have not had too many drama's luckily.

I have been told to drain it by some, and to keep putting fresh coolant in every 6 months by others as it goes off. Which box would you tick Hoony and others?

Yes draining is the the only and safest option from stopping corrosion , because of the magnesium content of the cast. But put a tag on the throttle , (no coolant )

Leave the water in with a good inhibitor. If it has no water it will corrode.

I got this seat cover today from the mob in en zed. I cant remember their name. Looks the goods, i got gripper on top as i found myself slipping off the back(imagine that!). I am going to get a trimmer to put it on better 'cause i suck at it. This thing has my '84 500 front end and rear wheel on it as it had upside downs on it. I wanted to ride the vets at the moderns and i sold my modern.The only other thing i did is put a nos rear guard on it as well.

what happened to the RE? i have never ridden an RE how do they compare with the RF? i think you posted once that you prefer the 480RD over the 500RE it that right or did i see someone else post that.

Reason i ask is i am thinking about one of the 2 air cooled pre 85's

Post by: 090 on January 30, 2008, 07:04:45 pm
I didn't oil the air filter properly, left a dry spot. I still cry myself to sleep. I do prefer the 83 as it has a broader powerband. A few pinging issues with the 84 as well.

Post by: 090 on January 30, 2008, 07:33:03 pm
Thanks Andrew.Hope you dont mind Hoony(hijacking the thread), i just took a couple of the 480. Talking about the 500 re, i reckon that the DG pipe might make it even more peaky, the band just seems real narrow. If i ever race the 84 again ,i will probably get GMC to make me one that broadens it out more.Other than that shes still a great bike.

 i own both a 500RE and 500RF...i found the 84 motor a lot more smoother and easier to ride than the 85...mind you i only rode it once and then parked her...shes gettin a few things done to make it a little better to ride..eg shock rebuild,frame welded and painted,new seat cover(this one didnt come from eco) ,clutch and so on....... and there was no pingin what so ever that day i rode it...nothin like my old yz490K anyway...mind you i absolutely luv the power of the 85 its a very very powerful bike...power ive never ever experienced before on another ride .... :o
Title: Re: 1985 CR500RF Rebuild
Post by: Hoony on January 30, 2008, 08:42:33 pm
highjack as much as you want guys i am enjoying the talk of Big reds. seems we all have 85's in common, as 090 said "with an 85', you know your alive",  but they are very ridable, short shifts are a treat, and even if my reaction time is not so good i allways get good starts.

the 480 looks the goods Brad. i am tending this way at present am will take some time to think it over as i have a lot of things on the go at present non bike related.

Whats wrong with the clutch Andrew?
Title: Re: 1985 CR500RF Rebuild
Post by: VMX Andrew on January 30, 2008, 09:05:22 pm
when i first took it for a ride id pull the clutch in, snick her into gear then she would start chuggin..wantin to go....got talkin to the local bike mechanic about it the other week and he said it would be a worn clutch basket..so i did the right thing myself and had a look and yes he was right..the basket has grooves all worn through it...and some hair line cracks... :o   is there an after market type  of clutch you can still get for this model..im thinkin barnett clutches,EBC or maybe honda oem might be the go...cheers :)
Title: Re: 1985 CR500RF Rebuild
Post by: Hoony on January 30, 2008, 09:11:55 pm
the hairline cracks are a worry, are you sure they are cracks and not casting marks? if the grooves are not too bad you can file them out/down carefully and get some more life out of the basket. uncommon for a 500 to have them i would think as it is usually the way with 125's and 250's (fanning the clutch ) yours may have done a lot of work maybe.

aftermarket baskets are available (Hinson is another brand) but pricey.

do you have a pic to post of the basket?

OEM price would at a guess be $600-700.
Title: Re: 1985 CR500RF Rebuild
Post by: VMX Andrew on January 30, 2008, 09:36:20 pm
sorry hoony no pics...i forgot there was another reason why i had it apart..the kickstarter return spring wasnt on the shaft..when id kick her over she wouldnt pop back in its place..so i decided to just fix that and slap it all back together and see how it goes..the clutch cable was completely stuffed too,the owner had a joiner half way along it cable tied together so i chucked that one out and put a new one in its place ..that might get rid of the chugging also :-\ just super keen to get another ride on her again....but i know for a fact i will have to get a new clutch basket....$600-$700 for a oem no way.... :o

i like the boysen flywheel cover hoony..makes it look real factory  8)..that spring you have on the shock looks like its aftermarket...is it a white power job... i might have to get some part numbers off you soon too from that book..ive gone over the 500RF and ive found a few things that need replacing, ill have too start hunting down...when the 84 is finished of course... :)
Title: Re: 1985 CR500RF Rebuild
Post by: Hoony on February 01, 2008, 04:05:06 pm
i bought the boysen cover because its metal and not plastic like the standard one, yes the shock is a white power.

no worries with the part numbers andrew, email me or phone me when you are ready mate.

G'day Woody, yeah i reckon the fork seal wipers are better than the boots. 43mm wipers i have on mine are OEM Yamaha 1986 YZ250S Part # 1LX-23144-LO but beware the Yamaha part is $36 each and they are a single item so order 2.

as for the stuff on Ebay thanks for thinking of me but i have that stuff already. i think there may have been an OEM owners manual for your 83' bike there a week or so ago.

Hey Tony, err Andrew  ;D no cracks in 86' frame i got it on ebay ex usa over a year ago, i had lots of pics to view before i bought it, it is very low hours, hardly any scuffs from boots etc, i assume it was a donor bike for the engine only. as for its history i do not know. mine could have been repaired and still can be and i am sure yours can be as well.

Nice one Hooney,

Looks Tops,

I've been away for a while guys and missed all the posting. I wouldn't back stepping a bit
On the magnesium water pump housing decay thing, I always thought it was more erosion from the force of the water/coolant  circulating rather than a chemical corosion thing.

Also Hooney (and others) did you dissasemble the tranny shafts completely to inspect or can you inspect them assembled.
About to tear into my 93 CR500 for a total rebuild. I will need help I am sure so will probably start a thread on it too.. Where can I buy an aftermarket Flywheel puller? Honda want my left nut for one of theirs. :o

Might be a bit early to fit in with your plans Firko but this looks like a decent bike maybe worthy of a bid.

Thanks for the kind words guys, appreciated.

That's a very clean bike you spotted there Quicky. had that been available 2 years ago i would have bought that one.

early CR500's that clean don't come up that often.

Firko, what model are you tending towards the Aircooled 1984 CR500RE ?

Utsman, i did check my tranny apart and found a 1 shim washer the wrong size and one missing.
i checked the shift forks for wear as well as the selector drum. i had ridden the bike numeruos times so i knew it shifted well.

Honda gearboxes from this era (1984 up) are very strong.  i have had a the same CR250 since 1987 and its done a lot of work (MX, dirt track, desert races and lots of 2 day trail rides with a big tank some years back) i have rebuilt bottom end probably 5+ times never had to replace any gearbox items other than bearings.

Hi Andrew,

i reckon that CR on ebay will go for around $3600. being a pre 90 bike it will not be in demand as much as say a 1984 model. i know of one (84 model) that went for $4k last year it was not  showroom floor immaculant, but a very clean, spend no money ready to Race bike (that's how i like them).

yours will end up just as nice too, i have no doubt.

i have just managed to track down a pulse coil and it should arrive mid next week. this hopefully should solve my no spark issue, its got me stuffed as it ran before i pulled it down. i have swappped the CDI and Ign' coils that i have spare to no avail.

Anyone really good on bike electrics? i have checked resistance of all coils and they are all within spec, output of alternator is ok. so this is why i suspect a pulse coil.


Anyone know how to test a 2 wire pulse coil other than resistence check ?
are they a like a proximity switch ?

Thanks Guys for the input, yes i have a good earth and no i did not powercoat frame.

pulse coil should arrive on wednesday so i will have another crack at it then. A big pissed off at present and i will wait for my frustration to subside before i attack it again.

Normaly DC*, How about a swap for a carton Walter ;D ;D ;D


* Relying on my dodgy memory

Here are the specs for a CR 480 will be very similar

Trigger coil Blue to green wires, 21-25 ohm, 5 Vpeak

no joy as yet guys. i have sourced a stator from ebay and hopefully and i maen hopefully i will get it from the US by next weekend as the Viper Social day is on. if not i will ride the 250.

I am very dissapointed at present, i either have 2 faulty CDI's or its the stator. time will tell.

Good luck Hoony. I wish I knew how to use an electrical meter and could test these things, but my brain power lacks full throttle. I think I would need to spend a day watching someone and writing down what they do and how the the whole damn thing works.
I can understand how a 2 stroke motor works because I can see it in motion but electrics are a different ball game, a bit like auzzie rules??
Life is sweet until you get hit with electricity.  :o

I think those funny debates are quiet good , as long as they are in sensible humor. After a stress day I always look forward to catch up with the happenings of the site . Its always interesting to see what Paul or Clarence got up for the day.Especially when I am overseas its great to tune in at the end of the day and have a laugh. As long as it is not at the expense of someone , it cant harm the site or the sport . The world is so agro and in a fast spin at the moment , it want hurt to have a brief laugh.  ;)The best things in live are ,at this stage ,still for free . After all footpegs , shocks or pine cones are not everybodys cup of tea.

have sent all the electrics to CAES in Melbourne to suss out for me. a very slight chance of getting them back by easter if not after easter. i have exhausted all i can, i even took my 2 CDI's to a mate who has an 1984 CR500RE (similar CDI's a slight change in part #) and one of MY CDI's had an intermittant spark. i am guessing the CDI's are on the fritz. will update later.

Hmm without giving to much away Hoony ;D

Carburetor is standard size modified but not 'bored out'
Reeds and cage, Carbon with modified reed cage(probably seen something similar)
Cylinder has some additional ports and transfer ducts have altered shape.Yet to move to a more top end bias in transfer durations.Modified exhaust duct.
Modified cylinder head
Pipe as you see to compliment the cylinder.
Ignition is standard but would like aftermarket CDI
Without a dyno it(according to the owner) sits between a 450F and a 650F(both Husabergs) power and torque wise.With igniton 60+HP would be easy.

I am trying to bend the ear of Calvin to get him to make a kit like this for the five hundy.These are for the TRX 250 trike these figures are NOT with methanol but petrol, no engines but a few gearboxes in pieces with the TRX.Another fellow in the US is adapting this cylinder to CR 500 cases.Used mainly for sand drags, it's the cylinder a CR500 should have ;D

G'day Rossenheimer,
long story (of which i will tell you went we meet up) but its still a no go, it has been running intermittanly and i did attempt to take it for a ride the same weekend of CD5 but it would not start (it did the 2 days before that). i can only assume that the CDI has an intermittant fault

i am now awaiting a complete ignition (ebay purchase) from a running bike to arrive from Yankee Doodle land early next week. the CDI for my model is a one model only unit, although the 1984 is similar physically it has a different part number. not many on ebay come up.

Honda changed nearly all ignition components from 1984-87.

especially when its fairly rough too Andrew.

I asked him a few questions about the piston kit (if it was OEM), the ignition (if it was OEM) and shock (if it was just rebuild only) as he  quoted these items as all new.

he didn't bother to reply!

i reckon its all a matter of timing with bikes when you list them as to what price they get. if there is no interested buyers then they may not sell at all.
Title: Re: 1985 CR500RF Rebuild
Post by: STW996 on January 15, 2009, 05:45:55 pm
Yes Hoony a lot of bucks for a bike specially if a race bike as it stands because if the pre 90 movement gets up and running it is the oldest of that class, sure with a good rider on it it would still be a front runner but it is always just the starter bike of the water bottle era.

The other side of the ledger is if you just have a real drive to own one or as in my case with the Red Devil could not afford one new and wanted one now that I could, then the sky could well be the limit?

To each his own I always say, hey Hoony old mate want to unload that 5hundy of yours? give ya 10k for it ;D ;D must be worth that if he can get that for that one hey?? As yours is riden but a TV star! but would have to be autographed :D :D

Hoony
I think you may understand my run of luck with a cr 500. I managed to find a nice 1984 CR 500 in the USA, it took 8 months to get a pink slip to leave the US. In the interim our currency went into a sharp decline relative to US dollar. Anyway the bike arrived, initially focussed on the suspension, got everything sorted. decided it was now time to start. Spark is weak and intermittent, it wil not fire up, I probably need to start from scratch and check all the connections, thereafter may need to have the coil tested. Any advice/ suggestions  welcome.

Title: Re: 1985 CR500RF Rebuild
Post by: 090 on January 18, 2009, 08:57:00 am
From my experience the stator seems to be the weakest link. Not to say they fail on a regular basis, just that the coil and cdi seem less likely to fail. Generally from water and gunk getting in. I would find out if the resistance readings are within spec.
The up side of having same/similar bikes, you can swap things over as i did. I took the stator out of my 85 500 and put in my 84 as it had the same issue and it fixed it.

G'day Crabman, what 090 said.

also they do have a weak spark anyway, make sure the gap on the plug is correct (from memory 0.030" i will check book) as this will also help.

in my case i had an intermittant fault with the CDI.
84' & 85' models are similar (difference part #) 86' on have different mounting (not sure if functionally the same, but i suspect not, as stator is also different) i had a spare i bought of ebay (seller said it came from running bike, but it was also stuffed, this caused me lots of grief as i assumed they both could not be faulty).

i was very seriously looking at a PVL for mine, but the cost was the issue at the time and another ebay item popped up for around US$100 and the exchange was good at the time. i had already spent way too much by this stage and i could not justify the extra.

good luck and report your findings here.
