Here's the problem,

Replaced Cam Chain for the second time, as I have to do it every year, and the bike wont start after replacement. Checked and rechecked timing, its good.

I don't think there is spark, layed spark plug on frame and nothing. Plus bike doesn't sound like its wanting to start at all.

Unplugged the kill switch and no difference.

I'm lost...anyone?

Check the resistances in the stator to see if it's been damaged. Also check actual TDC against the marks on the flywheel to see if the flywheel key is in place.
