Your friend should be using 80:1 full synthetic. Have him get a carbon fiber exhaust guard and then have him run the pi$$ out of it. The exhaust will get very hot (boot burning hot). Had this happen to my 03 SY many times when learning to ride (still can"t ride very well). I never opened the throttle even to clean the bike out. Hope this helps Cheers, DFW
