[johnnyb895]

I have a 49cc mad dog scooter and i am looking to throw a BBK in it and its alot cheaper for me to order one offline and get it installed and i was wondering if anyone has any suggestions in which BBK i should get. i know that there are different sizes which i am also clueless on.

plz help

80cc bbk (actual 72cc) seem to be the safest choice for engine longevity without going all out on stroker cranks , big bore cyl heads etc.to run the 50+mm bbk's imo. Simply adding a 47mm (72cc) bbk & use of proper carb. Jetting/upjetting will give the best power boost for the buck . Which one to buy? Thats where you gotta do some research/ homework. To see what suits you & your budget best. They average around the $50 range. Dont get cought up in those cdi,exaust open filter combo packages they seem to be more headache then help.

Valley Scooters has been a popular source of BBKs at low prices lately. Checl the dealers section of the forum for more info. PFS , eBay, and others carry them as well.
