cant do exhaust without cutting,try dropping to 40ml that should help thats what i put in mine also give it a good rev to clear it out make sure air filters clean
struggling to get bike to rev over id say about 2/3 of the rev range it feels like its holding back and spluttering slightly tried new plug cleaned carb altered clip position from 3rd still no better thinking maybe electrical cheers
just got a 2012 model its got jitsie pre filter aswell as standard air filter set up, but it seems a very noisy intake and i find it little annoying are they noisy with standard air box lid, has anyone got picture of normal air box top as i was thinking of maybe masking off some of jitsie filter to reduce noise but without reducing air flow thanks
