Auris
Tuned and Synch'ed
Recently I replaced my old mufflers for a set of used stock v65 SP (my bike is not SP) mufflers, which look almost the same only 2 cm shorter. I went for a ride they felt great. But after the engine warmed up it started hesitating when accelerating. It would idle ok, but as soon as I pull the throttle there is a sudden dip, once it passes a certain range the rev catch up. Since then I did almost 300 km with the new mufflers on and now even starting is difficult. I tried adjusting the mixture screw, previously it was just half a turn out, now around 1.5 turns out and seems to have helped a bit, but not good enough. The mufflers are quite loud so perhaps there is an an air leak.
The spark plugs are black and I spotted black stuff coming out of the mufflers. The previous mufflers were black so I may have not noticed that before. Am I running too rich or too lean? Or is it a coincidence and something else is wrong? I've always suspected the breathing circuit was not a 100%.
