Sportsman Flyer Build

Discussion in '4-Stroke Engines' started by Tom from Rubicon, Jun 6, 2016.

  1. This started here, (The trigger is pulled, 79cc Predator and purchased 5/21/16 Sportsman Flyer loop frame).
    But that was before I made the commitment to build one right.
    So far:
    Sportsman Flyer Drop Loop frame (Black).
    79cc predator engine. Governor removed.
    Sportsman Flyer fuel tank, got tank graphics also.
    Sportsman Flyer tool box.
    Mikuni 19mm carb.
    Sportsman Flyer intake manifold and my custom exhaust manifold to accept 1" I.D. SS flex tubing.
    Sportsman Flyer approved Felt springer fork.
    26" front wheel with Sturmey Archer drum brake. " Not Sportsman Flyer supplied "
    Flyers use a Worksman front drum brake wheel.
    26" Worksman 4136Rear wheel Shimano 110 helps keep drive train geometry.
    Tried to use a Q-matic transmission. Not drop loop friendly. So now the Sportsman Flyer approved Bully clutch is on the engine. $245 it better be good.
    Sportsman Flyer Reduction Drive is on back order. It is the set of components that will let this build start to flesh out.
    Wald steel fenders.
    Wald 867 handle bars.
    Schwalbe Fat Franks crème color.
    Sportsman Flyer 44t sprocket and adapter ( mounted to Worksman wheel 2/7/17 )
    To do the build I have built a bike stand that mounts to the chain stays @ 36" high. just like the one I worked with at a Schwinn Shop in the late 60's and early 70's
    ( The bike stand is performing flawlessly .)
    (Changed my mind when I started to estimate hours to reverse engineer the engine mount system that Pat Dolan already perfected?)
    I purchased Sportsman Flyers engine mount system, and wondered why I would ruin a Flyer build ?
    Pilgrims, don't mess with a proven design. I won't.
    Things may get deleted to make a more cohesive thread.
    Any and all responses, or links to resources that carry this project forward in a spirit that advances our hobby/passion are welcome.

  2. Just did a update on my last post. Most of the challenges so far are self inflicted.
  3. Ditto the above, still waiting for back ordered Reduction System from Sportsman Flyer. In the mean time I started another thread (bad me) dealing with how to successfully attach a fender to a Sunlite springer fork.
