450 Head Gasket?
Finally finished work on my 03 - 04 450 kodiak and fired her up on the driveway this week, I noticed a small amount of frothy coolant leaking from the lower radiator hose connection where it enters the rad on the left hand side of the bike so I grabbed the hose to see how hard it was and it was really hard - there doesnt appear to be any oil in the coolant or vice versa and it isn't blowing white smoke but I guess it could be due to pressurized combustion gases getting into the water system?
Will check the thermostat and see if its opening and also see if the fan comes on but I suspect it might be the head gasket so what I want to know is can the head gasket, piston rings and timing chain be changed with the motor in the frame or am I going to have to pull it all out onto the bench.
