I don't know how to work this site, like add links or pictures. But some interesting news; A chap in England is now reproducing reed cylinders to suit the 81 82 490.
price= AU$2532 PLUS SHIPPING. :)

is that the one mick deeeee;)

my question is is the head the same i seam to remember its different .dave mac
-
Bill Eyler is selling a factory reed barrel right now on ebay USA - reserve must be pretty high? Bill is an honest seller however.
It'll be interesting to see the pommy ones - but hate to think how much the postage will be ???
Heads are interchangeable. Factory barrels and I guess the repo ones are secured to the barrel at the rear by 2 x 10mm allen bolts as opposed to the usual studs through the base flange on standard models
Dave Mac :D

if you look closely you can see the holes

Hey - I know those cases and barrel - lol !!!
If anyone wants a close up I'll do my best to get some pics of either the black one or a blasted one I have. for a comparison I also have a Mossbarger conversion which are very well done after market machined versions that are rarely seen.

I saw this picture of a new cast 490 reed cylinder on the MXTRAX.UK vintage forum .I don't know if these are the ones that MICK-DE is referring to . I think that I read that they are going to use a nicasil bore , with no steel liner . I had heard a while back, that Eric Cook, from Maico Only in the USA was also going to make new cast 490 reed cylinders . I don't know if that has happened yet .
-
Now THAT looks the business.
Glad I obtained mine when I did though - the cost is pretty spectacular for the repos
Bill Eylers factory reed is sitting at $1200 and reserve not met (ebay USA #280319818534) with 4+ days to go
Nicasil sounds good - those barrels are already mighty heavy with the Teutonic finning, lol !!!
Who's in for one?
Dave Mac :D
-
some one in oz sold him a factory cylinder and when it arrive the fins were broken due to post office football games,it had to be repaired so this may be that very cylinder that has been fixed
true story
-
They are a bit of a wank really. They already pull like a fifteen year old boy from the bottom. I just can't justify that sort of money on a barrel. If anybody is going to buy one, i am interested in their original. Some champion cut all the fins off mine ::)
Thats not the barrel i sold him. He sold it a while ago for the price of a small country.
I sold the reed barrel to Bill Eyler in exchange for an mc 490 frame, Thor swingarm, Fox shocks, set of plastics, gear box set,mc cases and 80% of the postage costs. That is ridiculous.
I must say that the deal got a bit ugly towards the end with Bill, but he did come through in the end after much 'discussion' .
-
It's funny you say that - Bill really wanted one I 'stole' out from under him on ebay and he was offering me a king's ransom at the time to try and get it to stay in the US with him but I had other ideas and besides with his network over there I feel sure there are enough floating about to keep all those who want one happy if they have the cash.
My son's 490 is getting one and I'm unsure about the other two, and sure the 490's already deliver a mountain of power but the reed does tame it to a degree.
I am still at a loss as to why the mystical Wheelsmith fin trimming gets done. Lightness maybe - but a good crap on raceday will do the same thing, cooling must be compromised in hotter conditions and besides those big fins look the business especially when you take the time to straighten them all out.
Why not pick up an 82 barrel. a few well placed cold chisel cuts and the cast elbow comes straight off then the spigot can either be machined down to 81 diameter or easier still mount the carb with radiator hose and a sleeve in the carb. I've picked up a number of 82 ones for good prices and I doubt anyone could tell the difference in appearance or performance.
Dave Mac :D
-
Makes the $600 I paid look pretty sweet !!! Bill's reed is now $2,050.00 US - Reserve not met !
The benefits of the reed are debatable - the capital gain is irrefutable.
Wonder what it will settle at?
Dave Mac :D
-
Looks alot like a '83/'84 cylinder, are they interchangable?
-
Hi Brendan,
Short answer - No.
81/82 490 cases and cylinders do not interchange with later ones, nor do they make for a simple conversion with earlier models. I have read on the US Maico group that guys have modded the engines and cylinders to mate up but wonder if it is worth all the trouble if indeed it can be done at all. Perhaps someone can let us know?
Hey Mick pleased to keep you in the know re the reed I got mate - good thing is it is in OZ now ;)
Hope this helps,
Dave Mac :D
-
There is a huge difference between the '81/'82 cylinder and the '83. I bought a '83 reed cylinder thinking it would fit my '81 490 but as that base gasket shows they are a mile apart. Wulfsport in England have brand new nicasil reed valve cylinders for the '81 490.. No idea on the price though.
-
Looking forward to seeing sonny Jim stretch his legs in the not too distant future on the reed bike.
That gasket over base flange sure was a good way to demo the difference by the way. Thanks for your kind words Mick - I wouldn't mind a clutch or three either !
Dave Mac :D
-
I may be simplifying the situation here but why would you bother going to the trouble and expense to convert the '83 top end to the earlier engine when in reality very few of us are man enough to ride a stock 490 Maico to its performance potential.
With respect, to me all of this is just overkill "my Maicos tricker than yours" wanking. I also suspect that by fitting the '83 cylinder to an 81 490, youre making the bike ilegal for Evo.
-
Hey Old Phil
I agree with your comments.
The mates and i have a couple of the 81 490 things and a 81 440 thing and you dont need to hot them up. They go extremely well stock standard . Reed valve or piston port , they both perform exceptionly well.
-
Hi the maico posted by paul with the 83 barrel is mine and l can tell you it dose make a huge differance to the bottom end the std 490 power l would say bilds from 0 revs and keeps building all the way through were the 83 barrel u can be a gear higher and pulls a lot stronger but still puts the power down like a maico.
why you ask always built stock maicos never done any mods this time l thourt y not
paul
ps paul what u doing poting my bike
-
poting !!!!!!!! i dont do poting ;D
-
Whoa, Hold on Mick, I didn't intend to insult anyone. Maybe I should have put a smiley face in there ;D. I meant the wanking comment as a joke but I guess it sparked a response I hadn't intended. My apologies.
I own both an 81 490 and 250 and recently sold an '84 SC500 and agree the 500 is a quicker bike but my point is that I don't think the performance increase warrants the amount of work involved. I have no problem with people modifying their bikes as long as they keep them within the spirit of the rulebook. That's my other point. I've been led to believe that if a major part of a bike, the cylinder in this instance, is from a post evo linkaged bike, the bike must race in that class. If that's the case, wouldn't it make more sense to just race the '83/84 or whatever in pre 85? I'm just thinking out aloud, not trying to cause mischief as one forum member has accused me of in another thread. (firko thread)
Us Maico blokes need to stick together to fight off the forces of evil ;)
-
How do you modify the cases to accept the MUCH larger cylinder ???
Do you use the reed valve (83/84) crank cases?
-
mick i posted a pic of paul stackers secret weapon lol. aka meat head
-
Did you post it on here? If so I can't see it ???
-
Guess it will remain a secret ???
Oh well.................

Hi, i am Bill, Eyler, I Just joined and wanted to say Hi to all you guys..(hey Dave ;))
Bill
-
welcome bill ,i dont know were dave is apparently he raced last weekend and theres been no sign of him :D
-
Welcome to OZ vmx Bill! Good to have you on board mate.
For those of you who don't know Mr Eyler, let me introduce him.
Bill lives and breathes Maico's over in the States with some VERY VERY desirable bikes. He also runs a well respected outfit called East Coast Maico and can supply all the Eric Cook goodies. Not sure if you're still racing eh Bill - fill us in on the latest.
The racing in ACT is this weekend Paul. This weekend just gone saw me go over some of the stuff on the GP - God you should see the rear engine mount - talk about stuffed (I think it has had it's last official tighten, lol). I'm gonna run it on the Saturday practice to see what it is like before racing, and the following week it will have to be pulled down and the cases stripped for rewelding of the rear mount at least and the frame tabs straightened back to where they should be.
The right hand case just in front of the countershaft has a huge chunk smashed out and filled with a scrap of sheet alloy and Silastic so it too will be welded up and I'll re-machine it. Found that out when I fitted the PVL ..........Oh well, you live and learn but still a sweet bike and a fair price.
The rest of the bike is OK but while the engine is out I will repaint the frame as the current job is can over old silver - good from a distance but it is bugging me! The rest will do for now.
Cheers
Dave Mac :D
