Engine options.

Would an 1100 Aircooled engine fit into a GS550 frame, or is an oil boiler an easier option?

I would think it'll be tight Toni !!!!   an oil cooled engine would be a better bet.  but only guessing  

my mate squeezed a B12 engine in a Kat 400 frame but had to modify it. 

anything is possible

This is why I like OSS

Basically 1100 air cooled will not fit. You will need to do some very havey mods to the frame/engine cradle to make it fit.

Had a look one time at putting a gsx750et engine in a gs550 and it was no where near.

A gsxr1052 goes in well tite but they fit, the 1127/1157 engines will go but once in you can't get the cam cover off. Done both in the past.

I'm pretty sure there's a guy, he might be on OSS, who put a GSX1100 and later an oil boiler in a GS550 frame.

@bruteforce, wasn't that you?

guy in the kat club fitted a 600 bandit motor into his mrs's 550 kat, looks like it was supposed to be in there. plenty of 600 motors about for next to nothing.

Not sure how close the 550 frame is to 750 but the 1100 A/C engine fits easily in a 750.
