I just bought a used 03' polaris frontier classic fourstroke.So I am not familiar with it but I started it today to play with it and the engine had been idling for only 3-4 minutes when I opened the hood and noticed that the exhaust manifold and head pipe was glowing red.This does not seem normal to me. It would seem to indicate a lean burn condition.This engine has fuel injection and I do not know what would cause this to happen. Can anyone give me any assistance?

you knida bough a lemon sled. frontiers were discontinued half way through last winter cause the motors were to unstable. you might want to take it to a dealer and have them test all of the sensors. mass air flow, tps, and 02.
