Puch Polini + Mikuni VM20 Jetting

Polini/Malossi Reeds/VM20. Things are quiet on the tuning sheet. What are people jetting at? I'm guessing a 25 idle and a 200 main?

Re: Puch Polini + Mikuni VM20 Jetting

200 is probably way rich but can't hurt to start big

Re: Puch Polini + Mikuni VM20 Jetting

i had a 200 with a tm24 malossi 4 petal and ported intake on a polini

Re: Puch Polini + Mikuni VM20 Jetting

160-180 main jet. I had my hands in helping build one years ago, I think it took a 165-170 main and plug looked great, fast as shit too.

Re: Puch Polini + Mikuni VM20 Jetting

I shall test this. Did you have to play with the idle jet much?

Re: Puch Polini + Mikuni VM20 Jetting

22.5 feels pretty lean on the idle right now. I'm gonna try a 25 tonight when my jets get in.

Re: Puch Polini + Mikuni VM20 Jetting

I left the idle jet alone and messed with the needle when I needed to and the main jet. Both really easy to tune.

Not sure they will remember what they were running 7 years ago . ;)

Re: Puch Polini + Mikuni VM20 Jetting

I usually don’t chime in with opinions, but why such a huge carb for a Polini? I assume you are talking Puch polini... some of the best polini set-ups I have ever seen were 15 bing set-up that ripped all day reliable as hell.

Ditto that, and the kit comes with the intake manifold !
