I've had my original cans on since I wiped out my right hand Sil Motor can with lowsiding tomfoolery.
This weekend, I just fitted a set of ex-Rushjob, ex-Marko set of Ducati Performance cans (also made by Sil Motor as it happens - just round instead of oval like the last lot). I also got my battery charged again and started the old girl up (first prod of the button after standing for two months as well)
All I can say about the noise? Luuuuuuuuvvvvveeeerrrllllleeee!
