got a bit of bracing done for the top shock mount... I'm pretty sure that shock mount won't snap off!

my morbidly obese friend Ed did a bit of tinkering with the tachometer and speedo which I think is gonna look pretty good once the headlight etc is in place.

No photos to show tonight. Just mocked up the oil cooler, did manage to order a chain, sprockets and handlebars today, So might have some action photos tomorrow...
 
Picked up my 520 chain and sprockets today as well as some clipons. Bolted on the sprockets and draped the chain over them. The chain JUST clears the frame, so I'll get 3mm machined off the rear sprocket carrier and the same off the gearbox output shaft spacer. Chucked the bars on... Not sure how I'm gonna run them, but they're fully adjustable in every direction so I'll get the rearsets on and sort all that out.
It's quite hard to get a good photo angle of the chain clearance

Here's the bars, check out the bandit frame in the background... Not much left of it!

Wow! not a lot of clearance there at all.

Bruce.

Yeah, I knew it was gonna be tight! From what I've read, most people who put a bandit swingarm on a gs/gsx engined bike need to gain 6mm more clearance for the chain to miss the frame. I'll end up with 4mm between my chain and frame ( which seems to me like plenty) by only taking 3mm off the sprocket carrier and output spacer. All seems a bit easy really!!! Hope it works:-)
 
Great idea and nice progress

Did you find this on OSS?

You might want to consider more bracing for the additional HP
 
Where did you get the clip ons from? They look the business.

They're tommiselli bars... Not sure if I even spelt that right! I got them cause they are adjustable in pretty much every direction so I can really fine tune my riding position. They were about $250 new Zealand dollars. I got them from Boyle Kawasaki in Wellington.

Yes, thanks. I have seen that... This is where it gets complicated with the bracing. The new top and bottom shock mounts that I cut off the bandit have a wall thickness of about 4mm and the bracing I've added to these seems pretty solid.

.....what I really don't want to do is over brace certain areas and make them extremely rigid, if you make one section too stiff it will transfer its load to the nearest weaker point, so as I see it if you brace it, you need to brace the whole lot.

My next point is that a gsx1100 puts out 98 HP? And my 750 has the same frame, the bandit puts out 100hp so the frame can handle it. Im not an engineer, but I don't like the idea of transferring loads to all these different points on the frame that they may not like going, interested in any input anyone has on this topic????

got my oil cooler mounted and started playing round with my rear sets... As you can see in the photo the front rearset mount on the gearbox output shaft hits the frame tube. Does anyone know if you can get an offset one??? Otherwise I can just cut this one and weld it together offset. I'm getting to the stage where all the major stuff is done and now I'm down to all the little tricky bits!

Here's a photo with the rearsets tacked on, if I really focus on them they look like they're on a funny angle, but if you look at the lines of the bike, I think it's okay... Not completely sure yet though...

You've already got D covered, E is important for twin shock bikes

You may want to consider the C braces as this is the weakest spot as far as forces from rear to front are concerned

Yeah, the GSX puts out 100 HP now, but it can easily go over 130 HP, which is where the bracing comes in handy
 
rear sets look good to me. Its all on how it feels for you though.

Cheers, it actually feels like a really good position when I'm sitting on it, guess I'll only truly know what it's like when I ride it...... With the front wheel off the ground.

Have you tried rotating the gear change lever on the selector shaft 180 degrees and if that works you can cut the lever off the bottom of the brake lever and remount it on the top (if you know what I mean). As long as they are both moving in the same axis it does matter if they push or pull, and the gear change pattern will remain the same.

It is important that the levers are at 90 degrees to the connecting rod to get the best efficiency or you will miss gears.

I like the lines of the rear sets - they match the bike well. You wont know if they are positioned right (for you) until you've spent a long day with them. Trial and error for the best fit.
 
That's a brilliant idea gs58! I didn't really think about mounting the gear linkage up the other way, my mate Hayden reckons he already told me to do that but no one listens to him. I didn't think there would be enough room to run it above, but it fits sweet as. ( doesn't even hit my foot).

I also had to rotate the foot peg a bit so the hinge works properly.

Also got a few other things sorted this weekend. Got the battery box in and all the mounts for the electrics done, including mounting the coils. Modified the bandit side stand so it's short enough and doesn't interfere with the gear shifter.
