Smokey motor

[jack_rides_stp]

Went to a mates house and did the timing on his 110cc quad that strangly went out of time, and now sounds like there is somethong in the motor and it is blowing smoke out the breather thing out the back of the motor

And also running hot

What is this smoke

what colour is the smoke??

it may be running too lean, making it hot, and you could possably be getting detonation (sounds like a rock in a popcan).
