Hi, guys. I have a 1997 yz 250. a couple of weeks back i started smelling coolant after rides. I took my head off and found that my inner o-ring was like a inch to big. I thought this was the problem. Might have blown out. So i went to the local dealer and got a new o-ring, this one fitted nicely. I took it for a ride, and when i stoped it it still smelt strongly of burnt coolant. And if you smell the endcap the smell is stonger. this is why i thought it was burning coolant. Do i need to check if this seal has already broken and why does it blow out. I only held it on full pined for about 10 secs. why does my bike smell? :bang:
