Hi is anyone running one of these polini box exhaust on a std 200 moter I've got one just fitted on the tx 200 with a 122 but I think i just soft seized round the ring road slightly going up a steep incline full throttle. . Can't see much about jetting on the web and instructiond which came with it are for a different exhaust!! Scooter centres website says just 2 or 3 sizes up from a sip road 2 so i reckon I may need to be in the 125 area.

You've probably answered your own question No experience of the polini box but Ive read it is greedy... Go 125.
Ive just gone from a SIP R2 to 3 and went up from 122 to 125 on a moderately tuned P2. But not used it in anger yet. Early run out and it seemed happy on the 125
