Ok, I just installed a brand spankin new Yoshi pipe on my 2001 R6 and I was cruisin with my biker buddy Jesse(rides a 250) at night and he jokingly went to my right side and switched on the engine kill switch, after yelling some profanity to him, jokingly of course, I went to switch it back on and I hear a small POP, rarely heard, and he goes, WOAH man, you had flames comin out of your pipe!!! Try that again, so I did, this time around, lookin at my pipe and sure enough, when I put the kill switch back on the ON position it shot out a flame! It looked pretty cool at night. I was wondering if you guys knew what caused this, and if its bad to do and hurts the bike? I really want to be able to shoot out a flame on command but am afraid it will do some damage to my bike.
