Tryn to figure out why my buddys Kawi won't start. He just swaped engines. He mentioned it could be the 600 instead of 636 engine. Any reason why it still wouldn't fire over?

 

Does it turn over but not fire? or what

 

don't ask bubash, he'll call you stupid and insult your intelligance LOL

but yeah, we need to know if it turns over, if it doesn't, could be a main fuse, i've put 636 motors in 6rr's no problem, but i think i swapped the throttle bodies too...

 

It turns over. Gets spark. Fuel pump works. I'm gonna try throttle bodies. Just curious if there was ecu issue or something like that. I knew the fine members of SL could help. Haha thanks.

 

Well I think I found a problem.. There's some muddy substance on top of the valves... Hmm.. How the funk am I gonna get this gunk out?

 

i thought when you swapped motors 636 to 600rr they use different wire harness and ecu. did you also swap those

 

muddy stuff on the valves?! did they never change the oil??
