Have just acquired a rare aprilia 50 trials of 1981 vintage..... (similar to a fantic 50). It's got the obligatory minarelli motor but the carburations a bit, erm, fluffy! -runs all nice at tick over, ok on full throttle but not so good on the rest. Carb doesn't have a pilot jet, just a main and an emulsion tube. Anybody got a carb of japanese origin (approx 15mm) they would care to pass on for a good price......?

ps. or 125 honda 4 stroke motor.......
