Nice, looks like you want to do an Suzuki GS1200 ccm engine conversion.
I have all parts too but i am a little undecided between the GPZ/ZX 1100 UT or GSXR 1100 engine.

Haha I was waiting to see if anyone would notice that. I have a cunning plan (well i think it is anyway). I am going to build the Kiwi GPZ with a Bandit 12 motor while I am rebuilding the GPZ motor from the two I have. I had a bandit 1200 motor sitting in the shed with loom, carbs, etc and thought why not! If I don't like it no problem, just swap the GPZ1100 motor back in when it's finished. If the it's awesome with the 1200 motor in it I will build a 2nd GPZ1100!! How's that for a plan
.
Love what you have done with the mounts on your frame. Any chance you would be able to let me know some of the measurements of them? Would save me a load of time! Also really like the way you have done the front mounts. Looks like factory!

Swingarm is in now. Not 100% as I have a bit of work to do with the linkages to get it sitting right and working well. Currently I have put a GSF1200 shock in to work things out. The Mk1 Bandit shock is 306mm eye to eye and to get any height out of the back things jam up at the mo. I have a selection of lower links and will try a few different combinations tomorrow and see how I get on. So as she sits today it puts me back where I was about six years ago!!

Glad to see you back here!
I don't think you'll be disappointed in the B12 engine. I put one in my '86 GSXR750. It is a riot. tons of torque - very fun street engine. Header, ignition advance, and a jet kit and it will put 115-120HP to the wheel. They sound ragged as hell but i kinda love it. the valve train is very noisey.

do you mind me asking what bearing configuration you used for the front end? i used a ZZr front end too and had to have a whole steering stem made and pressed into the lower fork clamp. Ill be kicking myself if there was an easier way. Plus to make the rear shock work i had to take a bit of meat away from the swing arm to stop it rubbing, about 20mm if i remember but i used the older model arm Plus i had to widen the front cowl/fairing bracket? if that what we will call it to stop the forks rubbing on it.

Thanks mate, good to be back. My daily rider is a very sad looking and abused Mk1 Bandit 1200. I have had quite a few of them over the years and keep going back to them cos they are just such a great bike (and cheap). My beater is getting a birthday though and is slowly coming together. I bought a second Bandit to do the work too so that I don't have to take the daily off the road. Hence a spare 1200 motor lurking in the shed!

No worries at all. I used a triple clamp from a 1989 ZXR750 which bolts straight in and uses the same steering head bearings as the GPZ. All that is required to fit it is removing a small tab from the frame that binds up if left on. ZZR1100 forks are same diameter as the ZXR750 so a straight fit there. Forks/triple clamp clear the bracket no problem at all. I will post a photo later today. Yes, the rear end is going to take a bit of thinking. What shock did you use on your one?do you mind me asking what bearing configuration you used for the front end? i used a ZZr front end too and had to have a whole steering stem made and pressed into the lower fork clamp.

Wow.. ok that’s a whole load of work around I didn’t have to do.. ah well. I used a W.P shock I got from Scirocco, was close to the standard gpz shock size. Yea just looking closer and there is a big difference between the older and later swing arms. Not sure if you can grind away at the newer one and there are no pin bearings on the swing arm on the older ones.
