I have received the first parts for my winter project. USD fork conversion and rear Fat Tire mod with a FZ1 swing arm.

:good2:
Is that a 6 inch R1 rim? If so, you can install the rim with no machining if you take all 8mm off the left side of the swing arm. If you mount the 6 inch R1 rim all the way to the left in the swing arm, it will still be offset in the swing arm 4 mm to the right. Taking all 8mm off the left side of the swing arm will center the rim in the chassis. Then use an offset contershaft sprocket and you're all set. Some frames may require some minor grinding for chain clearance. Clear as pie? Easy as mud?

The front wheel is for a 2008 Suzuki GSX-R1000 17" x 3.5" and the rear wheel is for a 1997 Suzuki RF900 17" x 5.5". The rear wheel will be cleaned up and powder coated to match the front. I will be adding some color touches to both wheels that match the teal stripe on my FJ. The photos are an example of what will be done.
Fred
Gonna look nice, Fred. I have no doubt...
Bill
Very nice!
Amazing how the RF900 wheel looks like a regular Fj one.
Good luck with the conversion.
Reward yourself with a spin round the Ozarks
Andy
The color is close.....
Fred
What do you think Fred? Paint just the stripe to match or strip and powder coat with no stripe?

The above photo is the finished colors for the front wheel. The rear wheel will be fully powder coated jet black and get the teal decals like the following photo.
Fred
I think this is bike going to be a real beauty.
Chris
The project is proceeding slowly. The new rotors and titanium bolts have arrived.
Fred
All I can say is that wheel Fred should be mounted on the wall and admired while sipping on a fine port :good2:

Nah - it should be thrashed within an inch of its life!
It looks very Christmassy.

Stop it
You are making me thirsty
The rear wheel is not quite finished. Still needs a gloss clear coat and the decals to arrive
Fred
Hey Fred, when you get ready to install the rear, do me a favor.
Take some long straight edges, clamp them to the sides of your rear tire, and check to see if the center line of the rear tire is aligned with the centerline of the front.
Someone reported a 3/4-7/8" rear offset (to the right) on their GSXR set up (using a 4mm washer on each side)
I'm curious.

I will do that.... This won't be a standard GSXR rear wheel swap, as I will also be installing a FZ1 swing arm.

Should still be relevant if you are doing a "normal" install of the FZ1 swingarm — it'll be centered the same as the stock FJ swingarm.
I'm curious how much clearance between the chain run and edge of rim (or tire) on a GSXR rim

The clearance to the chain from the tire on my FJ1100 with 5.5 GSXR rim and 170 tire is about 1/4 inch or 7mm. Not much room for error.
Mark
The planned install of the FZ1 swing arm should pose no issue with tire clearance. The 1st gen FZ1 S designed to use a 180/55/17 tire.
Fred
Swing arm should be fine....it's the position of the rear tire/rim within the swing arm I'm curious about.
Align the center line of front and back tires first, only then figure out what is needed for the chain alignment.

I had a 1992 GSXR rear wheel on my '89 for 4 years and have change about that many tires on it. The first chain that I used was a Volare o-ring that lasted about a year. I put a new EK ZZZ chain on with a new rear sprocket. The chain had been on the bike for 3 years and over 20,000 miles. Along with this were a couple of rear shock changes, dog bone set ups and installing a hugger fender. At this point I had not done a tire alignment check, BUT.... I am sure that with doing the various work around the rear tire and 4 tire changes, I think I would have noticed if the wheel was 3/4-7/8 of an inch off to one side. Weird tire wear, no chicken strip on one side and a 1" wide chicken strip on the other? I will say, I periodically checked side wear on the rear sprocket and there was just barely a noticeable chain mark on the sprocket.
Mark's quote "The clearance to the chain from the tire on my FJ1100 with 5.5 GSXR rim and 170 tire is about 1/4 inch or 7mm. Not much room for error." With the 180/55/17 Conti's and the Shinko Verge 2's that were on the '89 when it was stolen, there was less than 1/4 inch clearance on either side. With the OEM Aluminum swing arm and centered shock of the '89 I can't see where anyone could get more than 1/4" off center without the tire rubbing the swing arm.
Could this be a case of someone with a 4th gen 1200 that has the offset shock and installed a '89/'90 aluminum swing arm
AND used the '89/'90 dog bones and relay arm? I have been told the 4th gen relay arm needs to be retained because it takes the shock offset back to center on the swing arm.
The first photo was at the 2015 Central FJ Rally and the 2nd photo is from the 2013 Colorado FJ Rally.
Fred
Thanks for the info on the chain clearance.
I was searching for a GSXR rim for a conversion, and found what turned out to be a Honda Blackbird rim that was on a GSXR being parted out - from the looks of the tire, it must have been off a road racer. Bearings are the correct size, but based on the clearances you are seeing, I will probably need to machine the sprocket hub a bit for chain alignment.
Thanks
Any reason why you aren't using a stock FZ 1 wheel? I am just curious as many have used the stock FZ1 wheel. Is it possible the GSXR wheel has the sprocket attached closer to the center of the wheel , thereby bringing the chain closer to the tire?
The stock FZ 1 set up has no clearance issues with tires, but needs an offset sprocket.
The rotors, 90 degree valve stems and bearings are installed. The finishing decals came in today.

I went with the GSXR wheel because that what I used in the OEM FJ swing arm and everything worked very well over 4 years. I figure at most I will need wider spacers at both inboard sides of the swing arm.
Fred
Should be good to go - Yamaha seems to be good about mounting the wheel in the center of the swingarm and the swingarm in the center of the chassis.
I think it was some Suzuki (maybe Honda?) parts I found a while ago where the swingarm was offset to one side, and the wheel was offset the other direction - it ended up centered in the original chassis, but would be a pain for other swaps.
It's kinda looking like a Tron light cycle. Should be good in the 90 degrees turns Fred.
