Gents,

I have run the old fourtrak up to until she's hot, held here around 2800rpm and monitiored bubbles (some large, most small and foamey) forming in the expansion tank.

To me that say's the head gasket is leaking!!!! Does anyone have the CD manual for replacing these? I could do with buying one, or having a kind individual E-mial me the relevent sections.

Would the coolant leaking into the cylinder cause a very slight stumble when driving?

Cheers

H
