I read alot about jetting kits. I ride every day to work all year round in the great british weather. (just need good winter gear). Im fitting a aftermarket exhaust and am having the bike dyno runned to set up fuelling. Whats all the ho-ha about jetting, I know a little about this and know its a performance thing, but what is the right course of action. I dont want the dyno people ripping me off with kits i dont need. Can you specialists out there help me with this problem.
Cheers
