i have a scrambler 95 and i got some major problems, when i start the machine i see air bubbles in the radiaotr, and if i drove it for like 5 min it shoots out if the over flow, also when i take the oil cap off after riding it i can hear air coming out of it, whats wrong with my machine , please help thanks

 

That happened to me last summer. The problem was that my radiator was covered with mud, not allowing it to do its intended job. I now hose it down after each ride, whether I get into mud or not. Hose it down from each side.

 

Bubbles in radiator? Blown head gasket?

 

if it is the head gasket also check the pump impeller

 

Head gasket or cracked motor, check the head first then carry out a leak down test on the cooling system but I'd say a warped head or head gasket for sure.
