That's a better setup than the earlier screw adjuster type.  Those shims will be easy to measure and swap.   Cool!
Rumor has it that Suzuki redesigned top end on Pop's Yoshimura's request. You get an extra 500~1000 rpm with the lighter rocker and shim arrangement Had a major issue when valve lift got toň high, rocker arm hit edge of ship and spat it out. Only the 600 and 750 ever had -shims, I havent tried retro fitting to 11/1200 head but I have some parts to try. You could fit 11/1200 top end to 750 but transmission would be weak point (1100 breaks stock 5 speed, don't think 6 would last long with extra power and torque?)
1200 Bandit should have 43mm forks? I sold the set I had, they are now on a GS1100 (posted pic somewhere?) Oh, I'm pretty sure I have some 0.5mm OS pistons for 750 motor. Can't remember where I stashed them at present though? (was going to rebuild a 600 motor I have with a 750 top end on it)

If i'm going to rebuild a motor for this bike its gonna be the 1100, or possibly a bandit 1200 motor.

front end sorted out. Took a bit more machining than I hoped for but it all came together. I used the bandit wheels, ebc rotors and original calipers. The rotors needed a bigger PCD, and the ID opened up to fit the bandit wheels. The calipers needed a small washer to center them on the disk, and since I was missing a wheel spacer, I decided to make them all from scratch and delete the speedo drive while I was at it.

Not sure how I missed this. Following along. One of these came up for sale locally not too long ago and I have to say I was very tempted.

the frame has been boxed in and braced. The broken motor mount is repaired. This frame is a proprietary alloy that is basically 7005. I used 6061 for the braces and 5556 filler rod. The castings were difficult to weld, twice I had something in the casting explode and pop molten aluminum out at me. I want to brace the swingarm as well, but I'm going to wait till its on the road so I can do a comparison. I painted the triple trees with gun kote and installed new bearings. I went through all the bearings in the rear end and cleaned them out and packed with new grease. Its rolling again, sitting on Metzler Sportec M3, which i spooned on sweating it out on the garage floor(I'm a Luddite when it comes to tire machines). Never ridden a metzler tire before, excited to try them out. I'm still on the hunt for an engine.

I know nothing about aluminum welding (very little about steel welding). But, as a GoldWing rider, welding extrusions to castings all with different alloys is a bit scary. It took Honda until 2005 (building 2006 models) to finally get theirs right.

Really nice bracing work.  I'm glad you haven't ditched this project.
