I cut the cdi and the scooter ran great. Then i rejetted the carb and the scooter showed no change it even seemed like it wasnt as quick as it was before the jet came with the scooter when i bought it I was wondering if there was something extra i needed to do to get more performance, or if i should just put the old jet in it. I know the jet that came with it was a bigger jet because they wanted to charge me to put it in so i just did it my self
