it wasnt i fixed that yesterday ive taken the top off so many time over the past few days i striped out a couple bolts on the top cover one of them on the small cover that covers the valve springs could that be the problem its not sealing good enough can it be loosing compresion thru the top cover

 

Valve cover has nothing to do with compression.

I agree with Jeffin TD. Check the compression. Now it sounds like valve gear problems.

 

ill check it again tomorrow but it was good thats the timing chain your talking about right i have to line it up with the marks on the flywheel how do i check the valves

 

could my cam lobes be facing the wrong way would that not let it start

 

As much as i dont want to say this you might have bent a valve. i would take out the spark plug and turn it over, if you can keep your finger covering the hole with air blowing out of the carb on the compression stroke, then your cam timing is WAYoff and like i said you MIGHT have bent a valve. let us know how it turns out tomarrow.

 

ill try that in the a.m. thanks for the tip right now id be happy if thats what it was im sick of trying to figure out whats wrong i have plenty of spare parts i have a spare motor in a thousand parts so i got plenty of parts

 

i put my finger on the spark plug hole and pushed start i could feel the pressure but i could keep my finger on it i checked the timing again it was a hair off so maybe its a bent valve im going to swap the top end with the other one i got see if that helps could my rings on the piston be gone?

 

ok i think i may have figured out what i did wrong i put the piston in backwards the side that says in is facing the front of the quad what damage could i have done buy running it the wrong way? it ran for about an hour all together the wrong way also theres some liquid on top the piston is that normal?if i turn the piston around will or should it work?

 

i turned the piston around there were little marks on the top of it where the valves hit it so im guessing i did bend one or two plus the oil on top of the piston must of come thru the top there was a little gap when i looked under at the valves so i think thats where it leaked thru i put my other top end on and its still the same i can keep my finger over the hole when i try and turn it over the timings on perfect does that mean these valves are bent too?

 

Do a compression test and get back to us. A REAL compression test with a gauge.
