valve sticking

[pigpin]

valves stickin on 400ex .... cold weather maybe???? didnt run it just hung up spinning over, then freed itself and got stuck agian..... maybe not oiling?

figured out what my problem was.... somehow two washers from the custom air box i had inside the boot to hold it in place came loose made it through the carb and head into the combustion chamber.... got really lucky that nothing is eat up or big hunks missing. Now i just need to get another headgasket and stick it back together!!

Anybody reused a known good headgasket with under 20hrs on it??? im not goin to but im just wondering, usualy after there compressed and sealed they want seal back correctly, specialy with 13:1 compression.
