what sized jet do i need, runnin a malossi mhr 70 kit on a gilera dna with a leo vincie tt exhaust and a 125cc runner 20.5mm delorto carb? any help? can run with standard air filter or with K+N style filter
the 86 jet in the carb will probably be about right.. they are 6mm jets same as the 25mm carb tho and as you know its trial and error. the pilot jet is usually a little big as its a 125 carb, ive run them unchanged on 70's befor now tho (lazy owners) with no real problems..
with an airbox drop it back say 10%.. thas around 76-78 ish. mabey a little lower but its trial and error as always. start on the stock jet and work down..
