Cant wait to check out this build. I use to have quite a few 650s back when i was around 16. Looks like you choose a good guy to help you with the work(les). He made my swingarm and custom made bushings for everthing, not to menton the frame bracing. Thanks again les, everything is working great. All this talk about the 650s and gpzs, make me want to buy another one. looks like this is going to be one mean 650. If your needing any engine work done that les dosent do, I would give john pearson from pearson racing. He does excellent work.

Something else to check...

If you raise the rear tire off the ground and detach the shocks at the swingarm you can grab the tire at top and bottom and try to twist it left to right to see if there is any play in the swingarm bearings. There should be none. Ed

with this wheel and lets say a stock kz swing arm that has been extended whats my option for brakes. i would love to use the stock brakes because when i have the stock kz swing arm extended i can just have those mounting locations moved around and can also save money and time looking for parts.

if this wont work what will i need to look for . i have found a couple of gsxr swing armes already extended or even a after market swing army built for the kz

i think my biggest issue is the rotor on the busa wheel is not going to match up with the stock kz brake caliper

Those parts are not from a 2004 busa. Iam running a 99-03 busa rear wheel and brakes. The caliper do not look like mine. After 2003 they changed the rims a little and the brakes also. The rear rim almost looks like it could be from a 99 -03.

any help would be nice

I think I'm going to go with an 08'Speed Triple SSSA and '06 GSXR1000 front end. That should be easy enough to get the project started. :ohmy: :laugh: :whistle:


Well I already pulled the fairing and the sissy bar! I'd like to get something a little smaller and sportier for it. I couldn't get used to how heavy the front end felt with the Windjammer and it really traps the heat on summer days.

I haven't posted pics yet but I've started working on a GS1100 swingarm conversion. I also rebuilt the carbs, replaced the intake and air box rubber and switched the points over to a factory KZ electronic ignition with Andrews coils and new plug wires. I also have a nice NOS Kerker racing system for it and a 3.5" rear rim with a 150 tire. I want to get new progressive front springs and a good fork brace. I also plan to do a 530 chain conversion and replace the front tire, along with a brake upgrade front and rear. For now, I'll probably just rebuild everything and go with EBC rotors and SS lines. Probably have a few other things in mind that I can't think of but that's the plan.

So in general, I'd like to do some mild, mostly period-correct mods like I originally did to my MKII in the late '80's. I really want to do a modern suspension conversion next but I'd rather start with a bike that's not so original for that project.

Oh, and it looks cleaner in the pictures than it really is....I've got a lot of cleaning and polishing to do!

Winter Project! Do the GS 1100 suzuki aluminum swingarm with 3/8 offset sprockets. Nice classy upgrade. I extended a stock swing arm 3" put a Dunlop 150 on a 4" Hog wheel. Burried this thing away for 5 years so far. Someday it will be worth something.

forgot to add I will be using gs1100 swingarm

looks awesome, I started working on the exact same bike last october too:

I see you're running pods and a shorty exhaust, did you re-jet and if so what are you using? What muffler/pipe did you use and did you just slip it over?

What headlight bucket brackets are you using, I want to cut mine off to lower it like you have.

Check out my last page or so, I think you'rs would look better if you get rid of the stock ignition switch, it's just too big for that area now. I used a 10 dollar universal one and relocated it down on the frame.

Have you ridden it much yet? I went to a 100 tire in the front and 110 in the back. Does your 120 in the back rub the swingarm at all?

Do you get slop in your front forks without the fender acting as a brace? Has it decreased the handling when you really get into the curves.

Where did you relocate things like the flasher relay?


Before I relocated the ignition, but still pretty current:

As far as what comes in the kit, you will need to fabricate a shifter linkage. I cut down my existing shifter, and used my existing drum brake rod to make the linkage. On the brake side it really depends on what you have. I had a drum but converted to a mono-shock swingarm with a disk. That made it pretty simple as all I had to do is position the master cylinder on my bracket. To make things even more simple I went with an integral pressure switch/banjo bolt which eliminates the need for a conventional switch.

FFTP sells several linkage parts so it's pretty easy to piece something together if you don't want to cut up your existing parts.

Cool. Do you have a picture of solution on the shifter?
It's a bit hard to me to have in my head right, I think it will be easier once I have the parts

I'm new to this forum so first I'd like to say hello. I recently purchased a 1978 kz750 with low miles for 700$. I thought it was a good deal considering it runs perfect and is in mint condition. The only problem is the guy that had it last tried a swing arm swap. Basically he took the stock arm cut it and welded Suzuki gsxr ends on it. He was trying to switch to crotch rocket tires and rims. After I bought the bike I noticed he wasn't the best welder decided to go original. Reason being is he sucked at welding and I would have to really mod the bike alot. I would have had to switch to single shock in the rear end an welded up multiple flat plates to support it. Anyway the biggest problem I'm having is reassembling the rear hub and swing arm. The front pivot part of the arm in intact but the rear came disassembled. I have all the parts just don't know how they go. I also have a book on the bike but it gives horrible descriptions. I'm used to working on dual sports and this bikes throwing me for a loop. Thanks for any help anyone can give me.
