if it were the cam chain tensioner, would it all of a sudden make that loud noise? i would think it would get louder over time and not all at once?

 

first thing that came to my mind was that when you stand it up, your depriving part of the head of oil, the sound isn't deadened by the oil, it's metal on metal so it sounds louder

 

well if it was depriving the head of oil... shouldnt it have gone away when i set it back down? its never done it before... thats what im saying. so by doing one wheelie, it shouldnt sound like that... i dont think.. its only got like 7500 miles on it...

thats what an oil pump is for, so the engine doesnt starve itself from oil

 

so true, but if the oil is away from the oil pump inlet, ie wheelie, than no oil can be pumped to the engine.

 

ok, in a wheelie, the oil will rush to the back of the engine... where the oil pump is... soooooooooo no. the wheelie isnt the problem... im pretty sure its the cam chain tensioner

 

You are correct on the placement of the oil pump. Had to look in my manual.

Have you tried what I mentioned above on the CCT? or speeds recommended method?

 

i bought the ape manual cam chain tensioner. i really hope thats it!!! i dont need to buy a new head ya kno? the guys shipping it out tomorrow. and this week is gonna be beautiful!!! this sux!

 

hahaha, right on.

 

soooo, its not the cct. im dropping the engine tomorrow morning. my buddy is going to start to tear it down top to bottom. first he will inspect the head. it might be a valve. im hoping thats all it is. cuz i have no money for a gasket set. if not, hes gonna crack the case..

this sux!

 

dang, pretty extreme. Keep us informed on the happenings.
