I cant find no centrifugal clutch supplier that is able to sell me a 3/4 bore centrifugal clutch that has a common 18 tooth sprocket from off of a coaster brake rear rim used by beachcruisers or the older BMX bike single piece crank bikes using the 1/2 x 1/8 standard chain that is not used on those multi-speed mountain bikes, I have an oddball 28 tooth rear sprocket on my mini-bike that uses a standard beachcruiser 1/2 X 1/8 chain, BUT-i bought the minibike as a rolling chassis without no motor having that weird 28 tooth rear sprocket on it and now i need either get somebody to *custom wield a 18 tooth bicycle coaster brake sprocket onto a 3/4 bore centrifugal clutch*, or whether or not if any of the clutch chain size #410/#415/or the #420 is the exact same size as a common bicycle coaster brake 1/2 X 1/8 size ? Im on a low income, so it would be cost effective to modify a $40 centrifugal 3/4 bore clutch that i already have using a #40 chain sprocket, to have a common coaster brake 18 tooth sprocket wielded onto (and overlapping the center of the size #40 sprocket) so i can use the common 1/2 X 1/8 chain used by the single crank bicycles-or if one of those three #410/#415/#420 clutch chains is the exact same size to a 1/2 X 1/8 bike chain, because i dont want to spend more on replacing the whole rear axle, rim and tire, along with the rear sprocket with rear brake too !, Especially dont want the aftermarket disk brakes, no point making a NOSTALGIA two wheeled ride if dont have drum or band brakes.
