I´ve fitted some mikunis that I got off a Paso being wrecked in the US (M750 originally), but I cann´t get the buggers to run right.
The bike shop said that was to lean when I took it in for a WOF , so I stripped them down and check trough all the post in this forum. From what I could tell they had the original jetting etc , so got some 140 mikuni mains and reset the clip back to the 3rd groove on the needle - still ran rough maybe to rich this time as the plugs were black & wet.
Got a Dynojet stage 1 kit for M750 and have fiited the new needles adjusted the mixture screw to 3.5 turns as well tried both sets of jets.
The bike starts ok, but idles rough until warm , coughs back though the carbs & back fires (with flame) out the mufflers, apart from scaring some children I haven´t had much joy with the tunning.... any help would appreciated.
ps 12v mod to the coils done & check coils are off a carb´ed M750 , new belts fitted
Sorry for the red herring.
