OK guys let's talk vm20 jetting (why haven't anyone added these to the spread sheet!?)
I know I'm not the only one running these, I have several of them on v1's/garelli/tomos's. I'm also running two vm18's, and unlike the 18's where I have my main jet dialed in I always feel like my 20's are just a hair off.
On my v1's I'm running 170-140 (polini/Meara/73cc Olympia)
175 on my tomos (77's 64cc race kit)
160 on my garelli (polini)
They are all dialed in on the idle/needle, but all feel just a bit off on the main, maybe I'm crazy and just looking to be re-affirmed here but....
What's your jetting?
