GSX750S katana GSXR750 engine swap

[dynodave]

So I have a GSX750S Katana fitted with a gsxr750 slabbie motor. Can anyone tell me which other oil boiler engine I can fit using the existing modified engine mounts? The engine has been mounted by the previous owner quite far forward, meaning that it has its exhaust directly in the head and does not have the short extensions fitted. Cheers

i think all the oil cooled engines are the same.

lower rear engine mount is smaller on the 750, but a drill will sort that, and carb intakes are different from various gsxr 1100/1200 blandit engines, so try the engine first, with carbs and filters to make sure they clear tjhe petrol tap and the side panel

yeah the bigger (taller) 1200 bandit carbs will get in the way of the Kat tank

i had to trim my side panel, as i had to move the engine over for chain clearance.

also fit the exhaust to make sure it clears frame downtubes

Thanks for the tips

best tip is to remove the sump and get some 2mm plates under it, on top of the lower frame tubes. this will level the engine and from here you can pack it upwards till the gearbox sprocket is in the right place, in relation to the swingarm pivot and rear wheel spindle, which is probably the most important part of the entire swap. see tony foales book for guidance
