I have a 150 yx with a dirtmax engine, I have just recently put the top end back together due to oil leaking out of the exhaust port straight from the factory. I have changed the rings and the valves and valve seals. Im now having trouble with the timing. I have set the piston @ TDC and lined up the cam with the mark on the casing. When I go to start the bike it does not fire. When I kick the bike over it dosent feel as if there is as much compression as before I removed the top end. Any ideas???
