110 has no compression - help

[hondaATCman]

I have no luck at all. I rebuilt the entire top end and its ran great for about 2 months now. Yesterday, it started on the first pull like always. Today, I went out and it has no compression at all, its like pulling a string without nothing on it. It has spark and I readjusted the valves and made sure the manifold was on tight. The only thing I can think of is the piston rings vibrated around and lined up with each other, but that would be a rare chance, then again, I have no luck. Can anyone help me out on this one??

Thanks

maybe a head gasket?

About the only thing I can think of is a bent valve. When you ajusted the valves how was the play?

Any other ideas guys?

Ok, I found out what the problem was, the intake valve had massive amounts of carbon and other junk around where it seats and it kept it from closing all the way. I'll have it fixed tonight and put back together and running within the next week.
