I've had a set for about six months now, I only got them for track days but decided to give them a bit of run to check the effect on the performance. I ran the bike with the baffles in for about 2 weeks and covered approx. 500 miles. They didn't seem to change the characteristics of the engine. Agree with henners it must run rich but I don't think it does any harm if you use them just for track days with low db limits. |
