right i have jst ordered a 72 jet.. and i was going to get some sports rollers and springs. i have a piaggio nrg mc3 ac 2002 does anyone know a guide or a know what size rollers and what str springs to put in. thanks. and sorry if other people have posted this b4
what spec is the bike? what carb/injection system is on it? what pipe (there are 3 diff stock pipes) filters, belt.. anything that you have done to it?
erm around 4.9 ish to start... anything from 4.7 up to 5.8 tho depending on the pipe. i know the reverse would run 4.7 with a 74 jet.
remember he runing a 12mm carb so i would say 5,5s with that set up or did you get roller with the pipe?
