Jetting Mikuni 20mm

I know this has been passed around a million times. I have asked Dratv and he wasn't able to help me out. So here it is

I have -

Ape50

Takegawa 80cc top end

20mm Mikuni
95 main
? Pilot
needle as low as it can go

Over Racing Exhaust

The plug is a little dark but the bike is back firing really bad on decel. Plus it just doens't run right.

Can anyone help so I don't go spending all my time running all over getting jets and not getting anywhere.

Thanks

Re: Jetting Mikuni 20mm

I'm guessing it's a VM20 with the quick change jet?

Try a 15 pilot, 110 main with the needle 2nd clip from bottom.

I have 3 of these carbs, and Fatcatt has a bunch also.

Alright I will have to find a 15 pilot and a 110 main. Thanks that will give me a good place to start.

DRATV used to carry both, but they have changed up their inventory recently.
