Hello guys. The spring is coming so I decided to upgrade my scooter. Its full stock now. It goes around 70-75kph. I am thinking about getting sport exhaust(leo vince TT), lighter rollers (around 5-6g) clutch springs malossi yellow and torque spring malossi green. The goal is to get +10kph and faster acceleration. Will these things do the job or I should get 70cc kit. I am open for any suggestions. PS. Excuse me if I have some mistakes. I am foreigner. Cheers.
