YZ400 wheelie problem?

Recommended Posts

i just got my yz 400 about a week ago and it ran great, i got pretty good at 4th gear wheelies and i can do them for about 1 mile or 1 1/2 at the very max and then today i did a small low rpm'd wheelie and shortly after my bike sputtered and then shut off. there was plenty of oil in it and i dont think im doing them long enough for the motor to start to have problems. has any one else had a problem like this with their 400????

Check you float height and make sure its in spec. Also you can loosen the top bolt on the oil line just for a sec. to make sure the oil pump is working.

Brown oil means a blown head gasket? I thought that it only means that some dust has been sucked up your breather tube.

Chocolate milk means water in the oil. That is most likely a blown head gasket or a cracked case.
