How right you are Keithy. I really do think that the Single can that I put on my Ten robbed the engine of power. It was toooo unbaffled and certainly was not tuned to the engine. Noisy does not produce power. The fuwl consumption went up as well. I went bakc to the standard silencer wnich Mr Yamaha in his infinate wisdom would most certainly have had his minions designing an exhaust to get the best from the standard set-up.
It's only us, when we start messing about that scrw things up. The popping is the AIS working, where a valve opens and allows clean air into the exhaust system effectively making it run very lean, hence the popping. It's for the emmission control. It's not that bad rally, compared to the single silencer that I took off.

Cheers Steve
