Gents,
I am restoring a 83 CR480 back to race spec. Due to reasons beyond my control I need to throw a rim on the rear hub. Yes I know about Buchannon's and no, I have never respoked a rim before.
I see all kinds of rims on the 83 CR's but can't find any info as to which model # of rims were used. Can someone tell me if an Excell rim off of of a modern bike would work or a part number off of a new rim? I would assume, possibly incorrectly, that a 36 hole rim ought to fit a 36 hole hub, regardless of the machine that it is on, as long as the lacing pattern is the same.
I realize that I am going to have to purchase spokes too and I probably will end up doing the front rim to match.
Am I missing something here in my thought process?
Yes I can send Buchannon's my hubs & a blank check & let them work their magic, for a price, a hefty one at that. I would rather save a few bux, do the work myself and learn something in the process.
Can someone that has experience on this shed some light on the subject?
Thanks in advance!

Wheels and suspension are the least likely DIY items. Wheels are worth learning to do.
This company gets alot of props in the vintage world.

I think Buchannon can tell you what Excel wheel you need but I think they drill the rim to match the hub.
You could also ask on Vintagemx.us
Just for the hell of it I decided to call Buchannon and see what kind of dollars I am up against.
Sun rims
Front 194.00
Rear 250.00
add 48.00 per wheel for gold
Excell Rims
Front 185.00
Rear 216.00
silver only
Spokes
99.00 per wheel
plus shipping
*Gulp*
I know some will say that it is the "cost of doing the vintage restoration" thing. And to a point your correct. I am just trying to be thrifty for a piece thats going to see the track. Not one that will only see the interior of a man cave!
They don't have a listing that far back. I assume this is their best guess for my application...
Front
21x1.60 36 hole IC(G,S,B ) -408 174.00 Fleabay 117.00
Rear
18x2.15 36 hole FE(G,S,B ) -410 195.00 Fleabay 130.00
19x2.15 36 hole GE(G,S,B ) -410 205.00 Fleabay 136.00
(G,S,B ) = gold, silver, black
They say the stock rims have a hole size of: front 7.5mm, rear 8mm
The Excel's have a hole size of: front 8.5mm, rear 8.5mm
Seems like I am getting closer to an answer.
I tried calling Full Circle Racing & had to leave a message.
The spoke nipples will be sized to work with the rims. It's all just a new learning curve, part of the vintage/EVO experience.

a pair of replacements. For a rider, you're better off going with a Sun. You could make a late model
Excel or DID rim work by sizing the spokes and nipples accordingly. Just tell Buchanans what you
have and they will sell you the correct gauge to work.
Lacing won't be too bad as there are only two sets of spokes front and rear (inners and outers).
You will need some kind of a stand to lace on - either home made or store bought. I use a Park
truing stand. They make everything from mild to wild, but the basic "cheapo" stand is all you need
and will set you back about $125. There are plenty of "how to" videos on youtube.
Should be a fun project and you might learn a useful skill in the process.

Im guessing its because i went up to a 19 (I can never leave well enough alone) I had to reangle the hole in the rim on 9 spokes. That set of spokes needed more of an angle. I didnt realize until I was tightening the spokes after a second ride.
My point is if something looks funky when you are building it, it is. Im the first I have heard with this issue so im guessing its because I changed rim sizes.
And take pictures of your wheel before you cut the hub out.
I was able to slide spokes straight in to the rim holes with newer bike strait pull spokes
Old school hook spokes needed room to get them in the right spot and just drove me crazy. I finally ended lacing them in their pattern and feeding them into the rim. I think i loosely zip tied them at the cross so i didn't lose my hard work when feeding them.
Im sure that is not how a real wheel builder does it. And you will get much more knowledgeable advice. Thats just my story of getting a new rim on the back of my old bike
to get buy on a budget ! period! Spend the money, buy complete match drilled set's, spokes from a good source!
You do not want to launch a CR480 off a jump, blow a wheel and break your neck!
Or worse crash into another racer and break his neck, because of a few bucks saved on
crap wheels.
I have destroyed front, and rear stock wheels on hard landings, and it does not end well,
do it right once!
