on www.50cc.nl they have different size rear pullys listed for the ciao... in theory, wouldnt a larger rear pully also help my low end problem?
the power is still an issue... i rode it down to the market this morning, and its a slight downhill there.. doing about 24-25... coming back up, i had to pedal it to get it going up the slight hill, but once it "caught", i was doing 24-ish again... probably the belt? fabio seemed to think that a loose belt (mine is certainly loose) would increase speed, since the engine would rev higher before catching the belt... but if this is the case, wouldnt that also affect my low end?
and it still looses power when i stop after riding for a little while and try to take off again... ? belt??
also, do you know what size pully is stock on the rear for the ciao supreme? if i decide to get a larger rear pully, i will need to know what size this one is (also with getting a new belt, the belt sizes are relative to what size pully i have)..
go to http://www.50cc.nl/frameset_eng.htm and click "performance parts" in the upper right, then "vespa", then "ciao", then "drive belt pully".. see what you thinnk...
