stressme posted a topic in CRF450XJust picked up New 05 450/x the third time I rode it I noticed the head pipe glowing bright red for the first 6 inches after riding about 2 min. so I removed spark arester to see if there was a blockage of coarse its alot louder but the pipe was glowing again in under 2 min. what does anybody think about this? when I say bright red I mean melt down bright red!!!!
