Mikuni 30mm Carb

[06apexak]

Anyone know the main jet size for this? I have it on my 81 Enticer 250 for my kid. When I bought the carb new, it came with a 270. Runs terrible mid range and up, pilot jet is 35. Can you clarify what needs to be a 1.5? I see some threads saying the inlet valve and others the jet needle.

Thanks.

its the needle valve or the needle/seat, same thing. if you remove the float pin and then the needle, take a socket and remove the seat, youll see there is a number ion it, and thats what they are referring to a 1.5,2.5,etc, usually on sleds youll use a 1.5
