After changing my oil the other evenong in my garage I started my bike and noticed the pipe started to get a nice red hot glow. All was well with the oil change so I asked my brother who rides an 02 YZ 426 if his pipe did this. His answer was no. I still am running the stock jetting with everything uncorked and after reading several posts I think I may be running a little lean and that is why the high heat. If anyone can confirm my suspicions that would be great. Or if the pipe turning that hot is normal, let me know. Thanks!
