Thanks Josh, its a 97 King Quad.
The red occurs both sitting still under light to mid throttle, and riding(20-30mph max speed). I shut my garage doors allowing lighting to become dim enough to watch the glow develop, thats when it sits still.
-Red can only be seen at night, not hot enough to glow in the daylight.
-Allowing the motor to idle cools the exhaust and the red dissipates.
-Everything is factory.
-Lots of power starts easy
I will check the plug and google plug chop as listed in a previous thread. Would you advise richening the mixture via a/f screw?
Thanks,
Mike
