Hmmm , I’ve just fitted up my PM evo 24 to my now run in Polini 180 PX150.
PM supplied me with a 108 , 105 & 102 jets…
I kinda expected it to be better with the bigger jets , as I took out a 98 that was in from when it was a plain 150cc.
Very poor stuttery performance with the 108 , slightly better with the 105 - and the 102 just gave me an easy 70mph.
Is this expected - and safe - as I don’t want to run to lean and mely the bally thing.
