Red hot header pipe

Well I went out this evening and started it up again and everything is normal. I could smell it running rich while cold, just like normal and the idle rpm dropped within 30 seconds and no red hot header pipe. This motor is liquid cooled with a fan and I have let it idle for 10-20 minutes at a time with no issues. Whatever was causing the problem has passed.

As far as the article goes, I don't agree with many of those guys who say it's perfectly normal and I have never had a bike do that when it is tuned properly. I am going to go pick up some ethanol free gas tomorrow and run it through it. Thanks guys
