Title: 82 83 cr250
Post by: Fenno on August 27, 2007, 05:21:45 pm
Just got my hands on both and 82 and 83 Cr250, the 83 was running (just) water pump casing shot, engine shot (bottom end/top end) rest of the bike is complete.
The 82 I was told is mostly complete but I haven't got all of it from the previous owner(just engine and frame so far).
So which is the better or rarest one to put most of my resto effort into and should I just devcon the waterpump covers or is there a better option.

I would say that the '83 is the go, i asked the same question myself with the 480's and was told the '83.Better suspension/handling for one.  Generally devcon is the go for the waterpump. I am experimenting with a two part araldite but its to early to know the result.

Definately the '83. Nearly everything is changed and improved on the '83. I raced both the '82 and '83 back in the day and the '83 was clearly better. It is a great bike. Cheers

thanks
have to see what turns up with the 82 but I think that the 83 will be far easier to start with. Should have it running by the end of september, pick up barrel and piston from being rebored 2moro and gaskets today. then just have to paint frame and put it back together.
Have you guys used a new style piston pin and clips (slightly different)with a new old stock piston ?
I have new old stock clips (they look like similiar to a key ring ring) but no new old stock pin (straight edge - new ones have bevelled edge)

Are you running a Honda piston or an aftermarket one? The circlips you describe are not genuine.

For your case drama's JB WELD is far superior to Devcon.JB handles well over 200degC.Machines far better than Devcon to.The circlip are  "spiral locks" painfully had to get in and out but the never come out.

Where do you live Young Pup?  Its not Simon is it, who races with us at Fairbairn Park (and who's a mere stripling at 32)?  I know he just got hold of two '83 CR250s (I thought) to do up and race with us in the old buggers class (ok, old bikes class). If so, up and at them mate, we look forward to you putting it to us.

I race an '83 CR250 at Fairbairn and elsewhere, and can guarantee that they are a good all round mx bike. Good power, good handling (despite what ADB said about them in the day), very reliable.  Parts cost, but you're worth it aren't you?

thanks lozza
Yes it is Simon, hopefully I will be running with you guys next meet. Dennis will be stoked to have another bike in the class. He was sooo keen to get me to ride his KTM last round. I like my modern KTMs and his handled very good so I am hoping that the CR will be even better. Frame sould be powdercoated next week, have most of my engine parts. So I just need to detail the other parts and put it back together.

if you need any help simon, give me a buzz at home on 6161 9325.  have a workshop manual if you need it.  another regular on this site, bruce mcfarland of red devil racing, got my pump cover fixed so could advise on that if needed.  did a good job too.  good tip tho is to drain water between rides, remove the cocktail so to speak.  good luck with the resto job too - they always end up more work than you expect so no beating round the bush - get stuck in.

hope to catch you at the heaven race at fairbairn?  or next club gig.

Simon, how's the resto going?
Title: Re: 82 83 cr250
Post by: Fenno on September 12, 2007, 08:50:26 am
frame powder coated engine is in (less water pump cover - waiting on seal kit)
serviced the swing arm bearings and waiting for a chain slider before I can put it on.
I have 2 shocks the 83 shock had a oil leak @ hose fitting, Tightened but don't know how much oil is left in it.The 82 shock is shorter but I think I have a linkage (steel one) to suit.
Should have another set of wheels soon and will make a good set.
Head set bearings on order should have them this week and then I can put the front end on. 
I will most likely put it back together run it in and then look at suspension set up and general improvements. 
I was watching your 86 on ebay looks like a good bike/buy
So will you be pushing to go pre 90 ?

Post by: Gerard De Ruyter (Twistandshout) on September 12, 2007, 09:14:41 am
You been hard at it Simon, so obviously keen to get it on the track and that's great to hear.  I think I have a couple of spare new water pump seals if you can't get one, but tell me quick if so, I won't include it in the box of goodies going with my '83 up north later this week.  Re pre-90, I just have to see what the rule book says about the '86.  It has drum rear and conventional forks (ie, not USD), so keen to get a view on whether that means its still pre-85 legal or not.  If not, I'll put it to the club to change the class to pre-88 (twenty years or older bikes next year) or pre-90.  You know of the vintage MX two dayer at fairbairn coming up in two weeks time?  Might be a bit soon for the CR to be ready for it but keep it in mind.  Maybe bring it out for a show and tell session sunday (race day)?  I've got to get a decision off Kel (race secretary for the HEAVEN VMX club) re whether me new RG (arriving today!) is pre-85 legal or not....if not, i guess i'll just ride the saturday practice.... :-[ :-[  looking forward to trying it out tho.  remember one line from a test on it i read....'pulls like a 14 yr old right off idle' - that means got some low down go - woohoo!! ;D ;D

what your 83 is gone already? now I cant have a sticky beek @ the next meet. 
what bits have you got I was supposed to get 2 complete bikes but the young fella that I brought it off cannot find some parts.
I have pump seals coming from evilbay US
Looks like I need at least another tankand seat,  I have two engines, frames and wheel sets electrics etc big job to get the other one running probally better off buying another wreck
does pre 88 mean that you can ride and 88 or only up to 87
Did you ship your new bike up ? if so how much

Post by: Gerard De Ruyter (Twistandshout) on September 12, 2007, 02:28:44 pm
took all of two days on the ozvmx for sale pages for it to go at $2800, so obviously a fair price (and a good place to advertise old bikes).  shipping new one in for $460 from adelaide.  if actmcc adopted a 'twenty year or older' class rule, then 'pre-88' would be the name for the old bikes class next year, meaning bikes made up to and including 1987 would be eligible.  but who knows, everyone might tell me to sod off, in which case i just come second last in every over-35s race and well last in the senior open class.....

i just like the idea of a powerband that is everywhere not just from halfway.  i loved my '83, and it has a nice broadish powerband, but still have to use the clutch a lot to keep it on the pipe to keep the speed up on the act track and sometimes its all just a bit difficult (and you roll over obstacles instead of jump them....).

guess that Ill have to look @ your new toy next round and  I will experience the 83's power soon enough
who shipped it form Adeliade - just for future reference

Post by: Gerard De Ruyter (Twistandshout) on September 12, 2007, 04:55:36 pm
fergusson racing australia shipped it.  they're in melbourne or vic at least.  they seem ok - easy to deal with on the phone; only prob was their driver didn't get the email job order and so missed a week that way, and still awaiting his call that he's in cooee of the ACT....let you know if pans out ok or not.

they're on 03 9747 1666 and do at least adelaide to brissy, probably more.

frig me - turns out the driver came thru canberra at 4am yesterday morning and thought it too early to drop bike off.....so kept right on going (up to brissy) - what a bright fellow!  fergussons assured me they gave him a caning for being a nong and refunded a good bit of the fee.  now we'll see if he manages to get it all right on friday when he comes back down...
Title: Re: 82 83 cr250

at least you got a discount and you will be really keen when you finally get her

Post by: Gerard De Ruyter (Twistandshout) on September 18, 2007, 08:52:57 am
yeah, as i said to you sunday simon, bike arrived 2am friday nite - bit ordinary that one.  i slept on the sofa so the guy could just rap gently on front door.  bastard never made me a cup of tea tho.  anyway, bike looked good in the middle of the night by the garage light, and pretty much as good on closer inspection the next day in broad daylight.  frame's been powdercoated recently which is nice, and engine sounds tight.  few spins round fairbairn proves that a power valve does add a good bit of poke, more importantly, all the way thru the rev range.  seems to handle well and soak up bumps fine too.  i'm happy with it!

btw, i have a spare water pump seal for you, will bring saturday to fairbairn for first day of heaven gig (think you said you might come check it out?).  will see if any other left over bits and pieces.
