Hey guy's and gal's. I just picked up a 04 R1 today and rode it a little tonight when I got it home, and while I was riding I noticed that when I hit 4k rpms that my Check Engine Light (Yellow light below the Tach) came on and stayed on for a few minutes then went off. Then when I got down on it again (4k rpms) it came on again.

Any ideas?
