The shop I go to said that I didnt need to buy a jet kit for my 2001 ZX9R when I put a pipe on it. They said they could put bigger main jets on it from parts they had and that it wasnt neccesary to get new jets. I was wondering what you guys think. Should I still get a kit or just let the shop replace the main jets and adjust the carbs. I would like to see the power curve smoothed out a bit.
