Will a k1 engine fit a k4 bike? (sv650) - SV650.org

can any one help me.
i brought an engine for my sv650 k4 and when it came it was a k1 engine how ever the company that it came from will not take it back because they said i may have had parts of it. i was told by someone that the engine would still fit so a friend helped me put it in. i swapped over the neutral switch because it was the only obvious wire that was different how ever there is no spark on the bike.

Well, if it's their mistake don't be fobbed off. If you have an advert or a receipt that states it was the engine you wanted then tell them so, don't be afraid to get legal advice - the CAB can at least get you started. They're pretty good at consumer stuff in my experience.

Original question:

Yes, as you''ve found it will bolt straight in. You'll need to change the inlet rubbers, the alternator rotor and stator with their associated wiring for your original ones*. If the top ends of your original motor are OK, use the camshafts too.

*The alternator is essentially the same, but swapping the lot means you won't have to alter any wiring - it will plug straight in.
