Oil cooled crankshaft GSXR1127 into a gsx750

[Supa]

Fellas,

Im pretty new to site and still finding my way around. Can some one direct me to the content on what parts swap with each other or can fit.

Ive got a 750 GS/GSX 750 Kat 1982 and lots of GSXR1100/750  engines.

Q1) is can I fit a 1052 or 1127 crank into the gs/gsx 750 cases

Q2) what size sleeve can be fitted to the GSX 750 block ?

Im aware I will need to bore cases for resleeving.

Idea is a 1127 crank into the 750 GS/GSX with GS/GSX1100 sleeves and 74mm pistons. 

And If its  then someone here has done it.

My calcs say its an end result of 1015cc. Gets me at a 1000cc Kat basically.

I have plenty to measure but I do not have a GSX/GS 750 crank to measure against.

 

Any help appreciated

NO! - GSX750 has plain bearing crank, 1000 & 1100 have roller / ball bearing cranks so totally incompatible + stroke on 1100 will no doubt catch on the cases!

he's talking about an OILCOOLED crankshaft.

Appalogies  - still a totally different engine and interference comments still apply

Swiss Toni, really appreciate the link.

Ive got lots of GSXR stuff that I am looking to retro fit to a Katana . Try to build what was available from suzuki to upgrade the Kat the way they should have made available.

 

Couldve released a trick Kat back then but the GSXR took the world by storm and rightly so.
