You'll be wanting a DOMA race can and a middle silencer eliminator,a re-jet and take the funny snorkal thing out of the top of the airbox.They eat sparkplugs and be sure to buy a couple of spare air filters,keep them oiled up and change as often as you can be bothered.MMMmm LC4,oh and if let your mates on it,advise them that changing from 1st to 2nd at about 10mph might lock the back wheel and throw them off!Love it,want it,need it!
