Comp will go from 10:1 to 11.3:1

You don't need to drop engine. If you take carbies off you can slip it off the back

Off the top of my head 550 for 750 and 590 for 1100

86 1100's don't have dogbones. You need a longer shock or an adjustable shock

I saw that for sale and was tempted. Have one exactly the same that I restored and fitted an 1100 to. If you're not too fussed about hp keep the 750 but if you want more, don't waste your time, just fit an 1100. It has some go fast goodies there already that you could use on the 1100 also

One of my completed ones

I managed to fit a Hayabusa damper

Exactly the same I'd say

I'm pretty sure lump is the same on 1127 pistons so increasing the bore 2mm and keeping everything else constant,ie stroke,combustion chamber, gasket thickness,etc, will raise comp approx .5. If the only element changing is an increase in swept volume then compression increases. On the other hand, if the lump is different between the 76 and 78mm piston then it's a different story. You will need to measure pistons to know for sure. Suzuki spec for both engines is 10:1 . Something to think about.

Very common poor mans mod. Gives 1109

Inside measurement of 750W rails at exhaust ports is 160. Gen 2 frame-190

Do not use a mismatched pair even if crank spins. That doesn't mean your tolerances are correct. You may end up with low oil pressure or spun bearings. Don't go there

The exhaust hits the lower frame rails.

I measured the 1052 head on my last build and it was bang on 26. Are you using fuel or water? Leaking through valves maybe? I put a smear of grease around the valves before measuring

26cc How are you measuring?

If you are going to bore out your 1052 block, imo not worth the exercise. By the time you pay for block machining, rings, 1127 pistons, gaskets, etc..... Better off getting a 1127 block (cheap) and 81mm kit. Will yield 1186, from memory, at not too much more cost. Difference, you will notice....You will need to bore your cases to fit, I've done it before with a dremel, easier than it looks

Dot heads are 22cc From memory, busa dish is 10cc Also need to make an allowance for deck height 59 x 81 + dot head + busa pistons x 0.050" squish gives around 9.5-1.
