The clutch engages as quickly as the original but takes much longer to reach maximum performance. So change your clutch springs! The scooter first starts up now at higher rpms and has does not have to overcome such a large rpm range to reach max performance. Result: You have a better start at street lights and have more acceleration. A definite must!
