TCK's GS1100ESD Gixxer/Bandit mod thread...

520 chain is the way to go. Some will argue you need 530 with liter class bikes, but the new 520 chains are plenty strong. The 520 Regina/Vortex combo I run now is the best wearing chain/sprocket combo I've ever had.

I thought the 'Busa rolled out the factory with a 520? Or is it 530? Either way, it definately douses the fire on the "630 on dragbikes" debate IMO. LOL

are there 520 offset sprockets available?

You can go to JT sprockets website and check their drawings. Some of the GSX-Rs and Kawasakis have a different offset than the Suzuki sprockets. I'm having one made up through Katman with a 3/8" offset. They aren't cheap but you can get them with any number of teeth you want and any offset.

Hmm all the stock gsxr bandit & gsxf front sprockets are flat (no ofsett) the spacing is done by use of a thick washer behind the sprocket

the kawasaki's that i know of with ofsett sprockets that can be used on suzuki's are gpz1000rx & the early zx10's (9mm from memory) but i'm sure theres more available in 530 ..... also yam fzr600 use the same front sprocket as most gsxr's if you need a 15 tooth in 530 (no ofsett)

imo using a 5/8 ofsett front sprocket causes more problems than it solves, around 12 or 13mm is whats needed for every gs or gsx ive done (about a dozen to date) changing sprocket carriers helps alignment as some are thinner than others & along with a little machining doing this keeps the chain well away from the frame

Brake arm and spro's

Another thought is you could just shorten the caliper bracket to fit the smaller rotor then it would bolt to the GS arm but would still need a kink in the torque arm.
As to the offsets Spro's, I have had much better luck with the 3/8" offset ones as the 5/8' push the chain too far out. I think you can still get them from Kosman and PMFR has some though most are in the 530 size. I am thinking to go down to a 520 once my present stuff is shot and needs the replacement. Oh, If the 3/8" works, you just go with the flat one and a few washers as long as the splines are still engaged. Works well and the GSXR1000 stock sprocket work with 17 teeth.
Does this help?

I've tried spacers but you can only get about 1/16" behind the sprocket before you are off the splines. That's as far as getting the lock washer on the outoard side to catch the splines.

A few issues


A few things to consider on the rear, when fabbing the rear bushings on the Bandit swingarm be sure to allow for the replacement shocks. The originals springs do not extend down as far as the Ohlins or whatever brand you choose. I had to convert to a 520 to make it work with the 180 Bandit rear wheel. As you can see from the pics its tight with the 530 set up. The 520 allowed for proper front and rear wheel alignment by giving me a much needed 4mm of spacing.
My parts list:
98 Bandit rear
180 Bandit wheel and rear brake set up
520 chain
520 5/8" front offset
520 48T Supersprox
Ohlins shocks
Welded shock mounts
Going with a Pirelli Diablo 180 to save 1mm also

2 other options here ....

pin & weld 2 stock sprockets together with the teeth removed from the rear one & the centre of the front one dished or cut out completely gives you around 9mm of ofsett you can then space it out as normal or....

for a couple more mm on the spacing you can machine the back of the nut down this allows you to still get the locking part onto the thread

do you have a chain runner on there as from the pic it looks like you have an issue with the chain chewing into the arm

I already have a custom sprocket in the works. I was going to go the welded route years ago using two sprockets but never got around to it. Chain alignment is already decent as it is, just trying to do a little better. I'm running a 16 tooth sprocket right now and wanted to go up a tooth anyway.

Runner

I have the runner, this was a dry run to fit everything

Dumb question perhaps, but keep in mind modern equipment is somewhat foreign to me still. What is a chain runner? Im guessing its a guide to keep the chain up off the swinger? But what is IT made out of to prevent IT from chewing up the chain, or being chewed up itself?
