quattrini m1x

For those of you who have this installed, how is the power/torque characteristic like? Can it be set up for slow speed driveability? I am not really after a high revving kit with little low end torque. Thanks.

Cambridge Lambretta in England do a lot with the Quattrini kits, check out their websites maybe ? I think www.vespa.co.uk is one of theirs.
