When my engine is revved I can hear a clicking noise coming from the front of my engine. And I've also noticed lately, that if I put it in gear on a hill, the gear won't keep it from rolling backwards. It's as if it's almost not in gear. I can easly push it backwards when it's in first gear.
Maybe I'm mistaken from what I heard him say. He did work on a warrior my friend owns. He unscrewed something from the left-front side of the engine and was adjusting the pistons to that. Something with a line and a T or F on it? He had a gapper or something that looked like one, and was adjusting "I think" gaps in there. Something about the piston being off. Maybe he has his terminology wrong, but whatever he did improved the performance on my friends warrior. I think he was telling me I need to do the same thing to my banshee.
