HEY! The owner says he has the caliper, the bracket, torque arm, and chrome braided line to go with the rim and tire. All for $175!!! All that would be left is a new sprocket and spacers. Jump on it?

I did the GSXR rear wheel mod on my 89' using a 92 GSXR750 wheel, caliper, caliper holder, caliper torque arm and 43 tooth sprocket. The 1st link is what I used as a guide. I followed it exactly as it reads, with a slight difference on the torque arm mount.

I did use the front foot peg lower bolt hole. I don't know if it differs from the year models. The threaded hole in the frame for the foot peg bolt was drilled and threaded completely through the frame. There is about 3/8 of an inch of available threads. I used a bolt with 2 washers that left about 1/4 of an inch of threads and screwed the bolt in. When I fitted the torque arm, the caliper was pushed rearward of the axle. I had the torque arm shortened 2 1/4" so the caliper hung directly beneath the axle.

I did change to a 38 tooth sprocket. I still have the GSXR750 43 tooth sprocket. It is in good shape If anyone is interested.

Hi,
I just bought a nice JT 40t 530 conversion sprocket for the GSXR1100 1992 which would include your year steel for 42.50$ off Ebay. I had to ceross reference it with the JT website because when you see it on Ebay it states that it is for a Suzuki GT750 A,B 1973-1974. But again it all depends on your preference. If you are going to do the mod then maybe think of changing the front sprocket to an 18 tooth. Randy at RPMracingca.com has one for just under 30.00$. He's a great guy and very well known with the FJ crowd and may I say very helpful.

Thanks,
Mark

Sorry forgot to give the item number 330853561970 for the sprocket if you want to take a look on Ebay.

Yep. Gonna do it. No brainier at this point. Thanks all. Mod will come mid season after the new clutch plates dissolve the back rubber :)
May be asking advice then on the subject but hopefully all this available info will make sense with the stuff in front of me.

Thanks again.

The black rubber thing is what motivated me to get into the conversion. Just about done and no problems locating parts and pieces. You just have to pay attention to what works. Sounds like you are getting the important stuff. Wheel, spacers (3 of them), cush hub, cush hub rubbers, brake caliper hanger, caliper, rotor and brake stay. As time go's along those parts will be harder to find. Even now to find a "good" wheel takes some shopping. If it's bent or dicked up then it shows up on flea bay...

The 93 GSXR 750 rim will work. Let me know if you get it. I would not plan on using the 93 brake caliper hanger or caliper. And you will have to but one spacer (10.00 item) cheaper than machining one down :).

Hey Brian. If you do go to Milwaukee. See if you can get him to throw in the caliper and bracket. If they aren't messed up. Ill give you $30 for them. The 93 750gsxr should be the same brake  as the 92 gsxr600 that I have. It has no torque arm. It just slides in a groove mounted on the inside of the swingarm. I want to convert the 86 to the same setup.
Let me know
Thanks Dan McCoy

Yes, if its a 1993 750 GSXR the caliper mount slides or mounts into the GSXR swing arm. On my 1993 GSXR rim I obtained a caliper hanger and caliper from a 1991 GSXR 1000. Slips right into place with the '93 750 rim.  Is the 600 rim a different width than the 750 ? This modding thing is getting to be a full time job Dan. Took a front rim over today to be stripped and powder coated.... Also ordered a Motion Pro Chain alignment tool to help with setting the chain straight. Then there's a new chain, damn.... $$$  :yahoo:

This is work in progress information.......For anyone using a 1993 GSXR 750 rim.

In 1993 the GSXR 750 swingarm/rear suspension had a minor change in design. The rim is the same as a pre 1993.  The internal spacers (one in the wheel between the bearings and one in the inside of the cush hub) are the same dimensions. But the 2 outside spacers (sprocket side spacer and the thimble looking one on the brake side) are different in 1993.
The 1993 and newer Left spacer is long and the thimble one on the right is short. This combo will not work, it puts the wheel way to far to the right in the FJ swingarm.
The 1992 and older     "       "     "  short "     "      "       "     "    "    "     "  long.   I think this combo can work ?

I replaced my left spacer (sprocket side) with a short one (pre 1993). So now I have a short spacer on each side. Giving me tons of room for washers/spacers to adjust the wheel/tire for center tracking and chain alignment.

I use the terms "short" and "long" for the width to avoid all the math :).  But I do have some measurements if needed.

Just throwing some information into the pile for what ever it's worth.
