i have been looking at some parts for my bike, i have seen some things i like but i have been told i should be using a 21mm carb, but i dont know what is best to use. i see two types http://www.pedparts.co.uk/product/1082/motoforce-racing-pwk-carb and http://www.pedparts.co.uk/product/1120/stage6-dellorto-21mm-race-carb-black-edition what is the main difference and what would you use if you was buying an Aircil Racing 70 kit? i haven't got anything yet but when the snow starts i will start using my car for work then i will start work on the bike
what bike you got and what have you done to it so far if you haven't done anything why would you need a 21mm carb
right now its total stock, i do have some parts in the shed but not touching the bike until i can say i have all the parts i need, then i will get some friends round and try to build it . bike is a 2002 Red(ruff) MBK Stunt I have some parts but not all, just what i have been told to get for now BMG big Valve manifol Polini Hi-Speed Evolution Variator Kit Athena Platinum drive belt PM Tuning Clutch + Bell AND looking at the aircel t6 piston kit i have a second question is the forum sponsored by any shops because when i was posting the part links i found that some was changed so they cant be used?
17.5, 19, or 21mm will do fine. I would go for a 19mm if you can find one as you will get better fuel consumption than on a 21mm without really loosing anything.
