Hi, i am currently stripping down my suzuki gk73a ( members Projects ) but had some trouble with the exhaust studs, anyway the upshot is ive snapped a bit of the engine off where the bolts go through i dont know if these can be fixed but i dont think they can, so my question is has anybody ever put a new engine in one or something similar, is it hard to do, is there much to change, thanks

The 73a is very narrow and i dont know of any engine that will fit.
