Hey all, I've been looking at the possibility of avoiding shelling out for a top end rebuild on my 80,000km K1 750 by swapping the entire engine out for a fresher one. My question is: can anyone tell me what other years/models I could look at for the donor? I want to go either 750 or 1000, and I know that K1-3 were pretty much identical... but what about a newer model? I'm hoping to do the job myself, which means no frame mods, the mounts will have to be the same, and I'd like to do as little electrical butchery as possible - my concern with later models is that they would require an appropriate ECU, wiring loom etc etc etc which is getting a bit too complicated. I've posted the same question on gixxer.com before anyone bothers to suggest that! (Thanks for the thought though...) :wink: Any suggestions, advice, cautions etc appreciated! Cheers, DH.
