Certain that it's losing spark? Or is that just your impression?
Yep. Out of nowhere, I get gas, air but no spark. I get ramdom explotions, and if i quit forcing the throttle, engine will stop. same as when you run out of gas.
It feels as if when engine is hot, the CDI pulse will not catch up with the revs, so it fails to get a continuous spark..
