Mikuni vm18 tuning help

I have tried 3 different jets, 2 of which 4 stroke at full throttle the other which bogs at full throttle, and I’m stumped. I’ve messed with the air/fuel screw and can’t get it right, is there anything else it could be

You are providing no specific information regarding your build/setup, and you haven't stated what jets you have tried.

How can you expect someone to give advice on jetting when you haven't bothered to put in the effort to give us the details?

It’s all stock besides the carb. The 55 jet bogs and the 60/65 fourstroke

Re: Mikuni vm18 tuning help

Put the dang motor on the phone . It would be more help .

DETAILS . Be Specific . Is this a '60 Checy with a straight 6 or a '99 dorito with a hubble and afterburner or ???

Who cares. Stock anything that is going to be a bear to tune.

The stock 30 idle jet is gonna be too rich for stock. Its too rich for most cylinder kits
