1100 sprocket size help

Ok, I can't find what the stock sprocket size is for my '90 1100. Right now it has 15 - front and 52 - rear on it. What should I get? I know it's personal preference, but I just want opinions. I'm not looking for a crazy set up with insane low end torque. I'm not drag racing or anything. I just want a good set up to have fun on.

Thoughts.....advice.....opinions?

oh, and this kit that Ballz sent me the link to says it's stock gearing at 15-48. I'm not sure if that is accurate though.

http://item.express.ebay.com/90-92-S...mdZExpressItem

looks ok to me, but I'm not sure.

Re: 1100 sprocket size help

Ok, so this chain/sprocket kit for the Katana says that 15/52 is stock. That's the engine I have, so what should I go with for my new sprockets?

http://cgi.ebay.com/ebaymotors/ws/eB...MEWA:IT&ih=007

If I have all these Katana parts....engine, sprockets.....what the hell makes my bike a gsxr? The frame? Oh well, I don't care what you call it. I like it. It's my mutt.

Re: 1100 sprocket size help

Stock should for a 91/92 be 15/48, its what I'm running on mine. I thought the 90 ran a 15/50, but I could be wrong. The 15/50 wouldn't be crazy by any means, when I got mine it was running a 14/50 and it was still controllable.

But what do I say is stock for my bike? Do I go off of what is stock for gsxr 1100 or a Kat 1100?

What were you running before you switched to the 46? I will be using my bike as my daily driver as soon as I get all the kinks worked out, so comfort on the highway would be nice, but not without sacrificing TOO much grunt.

What is your bike? A GSXR or a Katana? Seems simple to me...

GSXR with a KAT engint. It's a mut. Then I read that 14/52 is stock for an 1100 and that's what's on my bike now.....so what is stock for my bike? GSXR stock or Katana stock.

Re: 1100 sprocket size help

Allways tick with GSXR parts regardless of the engine model.
I would imagine that one day you will go back to a gixxer engine and then you waould want all stock parts.
The only reason I know people change the gear ratio is to turn them into wheelie machines...not that they need much help but mine was a 15-54 when I got mine and all it wanted to do was rip the wheel off the ground.
My opinion is go back to stock and like Srad said in another thread use steel sprockets because they last longer.

Sounds good to me. So, this looks like a good deal then?

Re: 1100 sprocket size help

Didn't realize it was a mutt. What year's your Kat engine out of? Maybe it has lower numbers... According to Suzuki, the 90 (GSXR) 1100 made 143bhp...

Re: 1100 sprocket size help

I wouldnt do that deal myself but thats just me, it says on that auction that the one pictured may not be the one you get.
Buy a DID X-Ring chain and then shop sprockets.

90-92 Kat 1100 engines are running claimed (by Suzuki) 136bhp ... so perhaps that's why stock specs put a larger sprocket on the rear to help it move along. Other factors come into play with your engine, like which carbs you have on them, and your exhaust, which were some of the differences between GSXRs and Katanas.

Personally, I'd go with stock gearing for the GSXR, and see how it w*rks. It'll give you a baseline for any future gearing changes.

I love D.I.D. chains too, I'll be putting a gold one on my bike this spring as it's due for a change. (532 down to 530)

Re: 1100 sprocket size help

Fox/Kool...I would work off the KATANAS gearing NOT the gsxr 1100's as its a katana 1100 motor and internal ratios will differ from the gsxrs. Keep in mind that katana motors have more midrange punch while pulling more weight. You'll need to decide if top speed or light to light acceleration is your priority!
For reference: 89-93 katana gearing is 15/52 with 122 link chain.
89-92 gsxr 1100 gearing is 15/48 with 118 link chain.

Re: 1100 sprocket size help

Srad,
Like I said earlier that I would go with the gixxer setup because if it was me I would be going back to gixxer mode and not Tuna mode.
But as far as Kool is concerned I would think you would wear out the chain sprockets before you changed to a Gix engine anyway.

Re: 1100 sprocket size help

I think anything between 48-52 teeth will suffice.
He's too new to really know what he wants or needs so perhaps a middle of the road choice at 50 teeth is his best bet?

+1

I'm not sure what I want, but what's on it right now just felt pretty good when I went for a spin.
