Also, Maybe off topic. Went on a spirited ride tonight with one of my buddies (lots of corners) Hes riding a 04 R1.( he has a hard time keeping up) All was well, kind of. Took a corner pretty close to the berm, felt the rear tire slide out

almost lost it with a car coming in the other lane. Held off the brake/throttle and rode it out. Made my hairs stand up. At the next stop, my buddies said my rear tire slide about 8 inches. Took it easy all the way home.
Digressing more; Since purchasing this bike, this was the most spirited ride I've been on, getting close to red line a few times riding out gears. My friend noticed some grey smoke behind me. Just once. is this oil burning/carbon build up burning up? The bike sounds great, no ticking, oil level is good. Should I be worried?
Only mod is a Trident carbon exhaust with the TORs map.
