Question about 2003 Yamaha YZ 250 F
If this is noticeable in the daylight, your fuel mixture is probably running very lean (not enough fuel) and you should not run the bike until you find out why (carburetor issue possibly). If you only notice this at night, a dull orange glow is not unusual, if it is bright red or goes very far down the pipe your mixture is probably lean.
If you continue to run the bike in a lean condition you will likely damage the engine severely, blowing the headgasket or burning the valves.
