Ok, so I'm shopping for a GSXR 38t sprocket for my rear wheel mod. I have a 92 GSXR 1100 rear wheel. Does anyone know if the GSXR 750 sprocket will fit the the GSXR1100 wheel? I'm on a TIGHT budget and every penny counts (and I'm super cheap) so I want save every penny I can since I need to buy a new chain and those babies aren't cheap. The 750 sprockets are cheaper than the 1100. Why? Heck if I know!!!

I don't know, but I know how you can check...
Sprocket Specialists has a web site where you can check if the sprocket part numbers match.

2) Don't store your FJ with E10 fuel https://tinyurl.com/3cjrfct5
3) Replace your old stock rubber brake lines.

A 1992 GSXR750 Sunstar or JT sprocket in any tooth number will work on a 1992 GSXR1100 sprocket carrier.

The sprocket carriers for the 1992 GSXR1100 and GSXR750 are the same.

Here is a 38t sprocket that will work.

IMO cancel the order for the alloy sprocket. FJ's eat them for lunch.

What alloy..... If aluminum then it might be short lived..... The FJ eats chains, and will eat sprockets faster when not steel. Unless you only ride it to church on Sundays and obey all traffic laws....
The glass is not half full, it was engineered with a 2X safety factor.

Tanks for the tip on that sprocket.....Dint find that the ally sprocket is a issue as you describe, Unlubed I can see that it would likely melt. But the maker said keep it well lubed and it will last so far so good.

Try to find the teeth on this Aluminum sprocket installed on an FJ....

More than just a tip, it is strong advise. I am sure you can get it to last longer if you can find it with a Hard Anodize finish. But then the cost might equal a steel sprocket.

I got my 38T '92 750 sprocket from Johnson & Woods shop near by. They are an old school shop and seem to know all the players in MC parts. They can tell you if the 750 sprocket will also fit the 1100 wheel.

If you use the alloy sprocket, please post on its endurance once a month, if it lasts that long....

Best of luck...

Better yet, try to find the FJ in that photo.

That's Kavin's FZ1.  He was riding that way with a passenger.  I still couldn't keep up.

I generally get 20,000+ miles out of a chain and a set of sprockets.  I can't remember if my rear sprocket is alloy or steel, that's how long I go between adjustments. 

If your FJ (or FZ1, for that matter) is "eating" sprockets, you have other problems:
- You adjusted your chain too tight
- You adjusted your rear wheel unevenly from one side to the other, and it isn't pointed straight ahead but is aimed off to one side
- Whoever did your machine work on the wheel swap didn't get the spacing quite right, and your wheel sprocket is not in the same plane as your countershaft sprocket
- You tried to save money by buying an off-brand chain or sprockets
- You tried to save money by replacing only one or two of the three components last time (countershaft sprocket, rear sprocket, chain) and the worn-out part you left in place is rapidly wearing out the new parts you just bought
Reg Pridmore yelled at me once
