Not really its more of just like sounds like a failed gear shift, grinding gears, but i wasnt shifting I normally shift at like 3-4k because I use it to commute often, or I take her for quick bursts to 10k rpms once in awhile in the back roads. But I was in first, left a red light, and opened her and stopped when i heard/felt it. It was fine over and under 6-7 but something in that range was not smooth. I kept doing it trying to pinpoint the source to no avail. I havent really opened her up but once or twice over 5-6k rpms since the oil change because I just commute/daily ride through town.
