Hi All, Completely new to the new scooter scene, used to build vespa and lambrettas back in the day, but now its my sons turn but he likes his Gilera dna 50 which we have de-restricted and now get a good speed out of after changing a few other bits but with a few problems to solve, The 'rev and go' thing is something i have not dealt with before, so beware... of a lot of questions coming your way, Thanks.
