im not 100% so dont go by what i say, but i think a slight upjet might be needed but not as much as putting a sporty exhaust, i think it has same main jet size as either the gilera ice (56) or my piaggio typhoon (53) so find that out and maybe try increasing by 1 or 2 on jet size it may not be needed this is just what i think have you actually got it de-restricted or are you going to get it de-restricted ? yet again terro or anyone else who knows what they tslking about tell me if im wrong and ill shut up
