Ignition Trouble

[Log]

This summer I rebuilt the motor in my 04 800 rev (new top end, replaced inner crank seals, and repacked crank bearings). I put it all back together and found it had no spark. But, if i pull it over backwards (by wrapping a strap around the clutch) it had good spark. I pulled the flywheel and stator out and everything looked good. The ignition triggers are in the correct order. I decided to swap the ignition triggers and it had spark when pulled over forward. I put it back together and it would fire a few times but the timing was off. Now i put the triggers back to the correct position and i don't know what else to try. I checked the resistance on the triggers and they had 230ohms each, which is suppose to be good. I don't know if it is possible for the crank to be 180 degrees out of timing or a bad trigger. Can any one help?

I would test the stator and go from there. Even when the triggers are backwards, the motor will just try to fire up in reverse. Which will yank your arm really hard and maybe break the recoil.

Check your connectors and wire terminals really well also. I know everyone says that, but it really does happen to be the problem more often than you would think.

I've checked all the connections multiple times. I tested the stator and it was good. I've got it pretty much narrowed down to the triggers or the MPEM. Any one else have any suggestions before I try to get a new set of triggers

Find somebody with the same motor and swap them out befor buying a set.
