Interesting Observation

Recommended Posts

Tore the bike back down again after the first ride and hearing a funny noise toward the end of the ride. Found out I didn't install the exhaust side cam chain guide right. :bonk:

Along the way I found this:

There is not one spec of carbon on the exhaust valves. I'm certainly not worried, just found it interesting. Anybody have an explanation? :bonk:

Normally it's the other way around! Exhaust valves are normally coated with carbon and the intake is clean.

Thats what I thought. Kind of weird.

That's normal for a very low hour tear down. The IN valves are cold in comparison so the carbon sticks... EX not so much so it hasn't had time to stick.
