Hey guys, so recently i a recieved a 82cc 54mm Prodigy Bore w/ head, and a Kuka pipe from a friend. My question is will i need to get a new crank to be able to run it? I dont have a lot of cash so im slowly buying things atm. CT mani, Oko carb, and 7:1 gears would be coming first. Any help is greatly appreciated guys, Thanks.

Yeah ive been lurking on craigslist for a af16 for a while now. What size crank should i go with? thinking about mini stroking it. New to the moped scene so probably gonna stick with the dd50 for now and scoop up an AF block later on.

why go mini stroker crank? just hassle to make new gaskets, play around port timing windows. tdc and bdc. crank piston stroked .

it had to to be done right at the first time!

waste times mini stroker crank.

If you like go fast, why spend money on dio big stroker 125cc.

get a jog! imo :2thumbs:

Its a 54mm bore w/ 50.5mm head (what the box says). Idk how im gonna get the old manifold off yet, some type of rivet or something on it. Ill try get pics for you guys.
