Hi gang.
This is getting frustrating. On my CB750 this went painless, but on my XS400 I can't get it to start, after changing my head gasket.
My problem:
It wont start. I get an occasional cough out of it and one or two back fires.
What I've done:
Had the engine out, the top end of, changed out the leaking head gasket, set the valve timing and valve gap according to my shop manual, cleaned up my points - set their gap to specs, used my voltmeter to set the points plate according to specs. (I might have fubbed up any of these settings).
So. The points are supposed to open at the low dead mark on the alternator plate yes? (Pardon my lousy english, I'm from Sweden). I get my voltmeter to go silent at this exact mark. I also did the 45 degrees counter turn to prevent any slack in the timing chain - and rechecked this. The points still open att this mark.
The spark look ok outside the motor. (New spark plugs).
I'va had the carbs off and got new main jets in those as well. They were cleaned last season and looked clean now as well.
Any ideas to what might be causing it not to start? Anyone with any usefull ninja-tricks to get it to run again? I need it in working order by friday..
Oh - and where do I connect the ground wire running up to the battery? The one coming out of the motor is obvious, but the other one? I cant frekkin remember..
Thanks in advance, Stabler.
