Hey Guys, so here I am jumpin into this full tilt... Here is my wicked plan, I just bought what I think is one of the last Fleetwoods to be had you know the inexpensive NuVinci Caddy. Well after having done a little research I can see the benefits of the CVT and had to have one but this whole bike cost what the hub and two wheels cost alone (not including tires) the disk break and aluminum frame, Bonus!! Now I plan to purchase the NEW 2011 4-CYCLE 49CC centrifugal (automatic) clutch BICYCLE ENGINE (huasheng 4 stroke) along with the 4 stroke shift kit (jackshaft). Because I cant afford the other bike right now I plan to build out the caddy first. I'm just a little concerned about the hub. Can it take the 4 stroke and what shall I do about the accelerator and shift indexer bottleneck? The throttle belongs on the right but the NuVinci indexer is there. I don't like it but not sure if I can change it. Has anyone got some advice? That is until I get the Chopper and tear the whole thing down I think it'll be fun to build the Caddy.
