Gettin doin on my gs1100 gsxr conversion

[katman]

Yeah, I've read just about every post available on the conversion. I'm running a 520 DID ERV chain since it's the narrowest. Katman recommended the 5/8" offset and I thought I'd have room to spare with the 520. Hmmmm... Well at least now it's all together. I'll just have to see about spacers and maybe a different offset for the front. Now for some wheel/chain alignment!

A 520 ERV is only 18.6mm wide. You should have room. What is your rear spacer sprocket side? YOu can't change the front sprocket without changing the rear spacer too if it is straight. I have done a number of these and on kats with no problems. The 530's are always tight between the frame and chain, shocks and chain tire and chain.
Also what swingarm are you using?

[katman]

So it seems like my chain isn't lined up too well. It's only about 2mm from the bottom of the spring as you can see in the pic and it rubs just a bit on the lower part of the frame under the swingarm. I still need to line up the wheel but this is pretty close. Maybe the 5/8" offset front sprocket wasn't the way to go?

Many bikes have extra weld 0n the underside where the chain runs. sometimes you need to grind some away.

I don't know what you were thinking but the chain won't fit with the same clearance as with the stock set up. some shocks won't even work with the 5.5 180 set up because the springs are too big. 2mm is lots of room in the conversion world.

Hey Rob. This is Josh in Brooklyn who bought the spacers from you for my 92 gsxr wheels in a stock gs1100 swingarm. I don't have the measurements on me for the spacers but I'll check. I'm going to play with it again on Thursday and see what can be done. I'll post results...

You are running the same set up I ran for a summer before I switched to the bandit arm. check the return run of the chain and see where its contacting. That's a wide looking 520. Measure the width at the pins. Should be 18.60mm. Shoot me an email and I can tell you how to get a couple more mm of room. The Chain looks pretty straight to me. You just need a mill or two more room to the left.

ONe more thing.. YOu are using the stock GS sprocket carrier right? not the gsxr carrier.

[katman]

Here is the problem with some kats Josh. Look at how far out the peg stay is from the frame tube. This will contact the chain on the return run if not removed.This can be a problem with the box steel which the motor mounts and pivot shaft go through. The welds on the inside can be a real mess.

I too am doing this conversion and have seen maybe 520 is the way to go instead of the 530 I have now. If I purchase a 520 chain, will it work with my newly acquired 530 sprockets?

[ironsheik]

Katman: Will shoot an email after I get some wheel then chain alignments done. Yes, I am using the GS sprocket carrier.

Nasty: You definitely need new sprockets. Katman has the good stuff!

520 will not work with 530 cogs. 520 is the same pitch but much narrower. YOu will need 520 sprockets.

So I got my wheels aligned and it looks like the rear is about 3mm to the right side which seems perfectly within tolerance (?) And the chain looks pretty spot on. What I just realized is that I failed to replace the cush drive rubber and it looks like a couple are thicker than others. This is making the chain skew from side to side as it rolls around. Hopefully I can pick these up on Monday and after bleeding the rear brake I'll be ready to ride. I still need to figure out why the Bandit speedo drive I got is too short though... It's the same length as the gsxr drive I got with my front end.

As of now:

BTW: Anyone want to trade my Yosh race exhaust that requires the center stand to be removed for a street version? It's in really great shape.

Iron,

The sprocket carrier does not run on the cush drive. The cush is for acceleration and de-acceleration dampening. The carrier has to torque up to the wheel bearing. If the cush is for some reason too wide?? it may keep the carrier from torquing up to the wheel bearing but I don't think that is the problem. Take the cush out and check spacing again. IF the cush is in the way of the carrier the lateral forces will explode one of the bearings.

You didn't get it off fleeBay did ya? Are not the gsxr and bandit clocks the same distance from the wheel?

Got a pic of it? I have a street version that I bought off of another member (it's currently in transit) that I MIGHT be willing to trade.

Busa's with 240 tires run offset right. Also, some Harley's come factory offset right (interesting?? no not really).
