Welcome...I too have a 77 B1. I believe your motor will fit into an A1 frame or any frame that had a kick start motor....but I am not sure why you need to do that, why not just get a swingarm to fit the frame you have? One of the cool things about the B1 is that the swingarm comes with needle roller bearings as stock which goes a long way to improve stability especially if you change out the steering bearings to modern roller bearings. My bike was cafe(d) but I am changing it back to more stock cause it's not so good on my back. Running wire wheels on it will be really cool, try to get a front that has a twin disc setup. What else are you planning to do to it? Also post this in the projects section with lots of pictures, plenty of people on here with loads of technical advice....I'll be watching

might be just rehashing this, But i have a 96 GSXR 750 F.I. Srad sitting in the garage now that has no spark and because it was a totaled bike but is rebuilt almost. makes me wonder how tough it would be to put it on the frame of my KZ750 that is a 79. the gsxr is pretty much complete other then the head light and the right side clutch controls .
but i have seen several on here that have changed the rear swing arms from the early gsxrs to the KZ.

can you let me know if you have build thread on your bike? ya have me thinking of doing something like this instead of the fight for a title etc... on a totaled bike. besides i got the whole thing for 300.00 because of the no spark issue so tearing it apart might be even more fun then trying to rebuild it

There are many hours that have gone into my '83 KZ1100LTD since I got it back as a pile of parts from a very, very naughty shop who was hired to swap shift forks (no, I didn't whack the forks). Many wouldn't believe what they took apart, which is a story for another day.

So, in the final stretch of restoration, readying for a first run tomorrow, all together...I am putting the rear wheel back on. Headed up to the FSM 101 ft-lbs torque in the rear axle nut, with a piece of heavy PVC extending the bar side to fix it in place and working up on the nut, I hear a "click" or "clack" kind of like something adjusted in the holding rod or pipe alignment.

Well, the 101 ft-lbs comes to bear and lo and behold, the wheel hub is TOUCHING the final drive. There is no motion.

My thinking is this: I have collapsed something in that final drive. I think this because when I look at the wheel assembly (including bearings, spacer, brake, and swing arm everything is 100% contact. The only place I see it isn't (again FSM) is the final drive.

I am sure glad this didn't happen on the road. Need advice. Is the FSM 101 ft-lbs overrated, like 87 would do? Any ideas what may have "popped?" FSM shows a snap ring, paired oil seals, etc.

Anyone else had this happen?

Wildly, would the final drive off a 2001 Mean Streak fit? Got one in the garage and it looks oh-so-close. The axle bolt matches diameter and thread but is longer for that wider swing arm. Thinking I just might check the measurements and splines tomorrow.

Not much progress as of yet, and I'm still a hundred miles from the other photo database, but I'll post what I just received in the mail, via Royal Post.

Since I am using a modern fork I have to use an electric speedo, so I found this Velona Daytona 200 at digitalspeedos.com. Very nice people to deal with and it showed up quickly. I really didn't want to replace the stock gauges, I liked the big dials, but I wasn't finding a good quality electric sweep gauge the same size. So why not put this one into the stock housing? After about twenty mins of carefully opening the case I did manage to disassemble it and wrap the old clock up for safe keeping. And what I got was this:

I think it looks pretty good, a little bit like some modern bikes with one clock bigger than the other. Since this is just a mockup it didn't take any pics of putting it together (the ring inside the housing is a coffee can lid), so when I machine up the aluminum ring I'll be sure to document.
And a few more pics of it bench testing:




Thanks for the comments and the warm welcome, I'm hoping to keep updates pretty regularly now. Bluesmoke, the wheels are late model R1 wheels, tricky to get into a GSXR fork and ZX636 swinger but i'll detail that soon.
Back to work

Plus the caliper bracket is "armless" so you would have to weld a stay of some sort onto the arm if you flipped it.

There was a non-braced Gsxr swingarm in the classifieds at one time that could be set up with the same wheel fairly easily and the bracing wouldn't be a concern.

Doug,
I'll look at it again and measure it, but it looked pretty symmetrical to me. I didn't notice any difference when I put the chain rub pad (black nylon pad) on the other side, when I flipped it 180.
I already mentioned the caliper bracket. It's an easy fix. Just cut off and weld on the other side.

the overbraced arms like testa's presents some interesting challenges when trying to dual shock one.

a busa arm with the upper brace removed and an underbrace added would be ideal to dual shock a kz with.
imho,

Leon,
I've thought about the GSXR overbrace problem and that's part of the reason I wanted to see what others might have done, before I told my idea and was thrown under the wheels of the bus.
I took a good look at the GSXR swingarm and see no reason I can't flip it 180 degrees.
I'll have to switch the brake caliper mount and chain wear guard (black nylon piece) to the other side.
The overbrace, would now be an underbrace.
Try to imagine testa's bike.

With the swingarm like this.

I even looked at the ground clearance and it looks like it should work. It doesn't look like the bracing would hang any lower than the underbrace I put on my 1978 LTD.

I haven't done anything with mine.
I now have a 1995 GSXR 750 suspension I'll be using on this bike. I may put the GS1100 swingarm on my 78 LTD1000 this winter, but it already has a underbrace I installed on the factory swingarm.
Not sure what I'm going to do with it now?
Sorry, I can't help you with your polish question at this time. I did do some engine parts that were in bad shape. I just wet sanded them in the kitchen sink when my wife was gone.
Started with 220 and ended with 1500, then a little mothers mag polish.

Can any of you offer suggestions to polish a GS arm? It looks like it has a silver coating on it from the factory? Paint? Not sure but it's not plain aluminum. I don't have access to a blaster. I'd prefer the polished look over painting it silver or black, just not sure where to start on this. Didn't realize it had a coating.

All the pics look great, btw. Can't wait to get my GS arm on my KZ. Thanks!

it ain't rocket surgery :woohoo: !

I wanted to see what it would look like and thought someone might have already done it with a GSXR swingarm.
If I could do photoshop I'd already taken pics of testarossa's blue 78 KZ1000 with the 1995 GSXR 750 suspension

and added a different styles of sport fairings, chin scoop and shocks, to give me a better image of what the end product will look like.
I really like the look of my old 78 LTD

P.S. I was just getting ready to P.M. you back anyway. I'll get you the info you need as soon as I get a chance to go look.
