Hey guys, just wondering. Is their any other engine out there that a xs650 frame can accept? I know with plenty of work you could make any engine fit. But is their anything that you could put in easily? or with mild work?

Like something more powerfull?

Thanks
 
I am sure the engine is the main appeal of the XS, which is why so many engines are borrowed for custom builds. You have a point though - for every new custom framed build with new chassis parts there's a rolling chassis looking for a new motor...
 
I might just throw a 250 Ninja motor in this summer just to see what it feels like to rev the XS to 12K before shifting.... :)
It'll probably grenade trying to move all that weight... Have to put the leathers and boot on.

I'll have to bungie on the radiator though..
 
gpz 500 might fit but with all the hassle, you might as well put a big bore and cam in the xs engine
 
Anybody ever put an electric motor in a 650 frame? You can buy the kit with the motor, controller and throttle for about 1K. Can you tell I'm bored here in the frozen tundra of Wisconsin!! Go Pack!!!
 
Wow, what timing... I was offered a complete R6 engine with FI, sensors, wiring harness and radiator... Hmmm. Twice the HP, but a small quad. Might be a cool swap.??

There's a guy on CL that has a XS650 with a FJ600 engine installed and a while back there was the diesel powered XS posted here.
 
not sure why you would want to swap in another engine?? The one thing everyone is changing is the frame... different swing arms, forks , hardtails , increased bracing... and so one. I agree with what someone said earlier that the engine is the attaction. If you want a different motor I would just get a different bike...
just my 2cents
 
so buy a KZ750? why would you go to all that trouble. Thats like swapping a cb550/4 motor in an Xs when they both in 70's trim look similar.
I agree....it ain't too practical. But the man asked a question and I was merely pointing out what I considered to be a reasonable answer. Let's face it....many of the things we do in our builds aren't exactly paragons of practicality. Just doing something because its different or a challenge is why a lot of the folks in this Forum do what they do.
