Howdy all! Long time reader, first time poster I have a quick question - Ive just bought a Bolwell Retro 50cc (also known as a Bolwell Jive), and top speed would only be about 60 or just above. I used to own a Bolwell Jolie, and I heard that that came derestricted from the dealer. Im wondering if the Retro is restricted, and if anyone knows how to derestrict it, and what sort of power increase I would get. I'm also wondering if anyone has had any experience with performance parts on these scooters. I'm thinking of sports exhaust and a big bore kit - What sort of increase in power would I get, and if there anything else I should be thinking of doing? Thanks in advance for your help.
