Need help with a tuning kit, how do you tune your scooter, which kit should I choose, and all general tuning and modifcations questions are for in here.
I’ve got about 3k miles on kit and it now needs to be down jetted. It was running slightly rich, but then it started to feel too rich and I cured by dropping a jet size. I’m wondering, what’s going on? I’ve never had to down jet like this before.
