Ok, sorry about not getting up very many pics, but i have bean really busy, working most days 8am to 8pm when i can, sometimes kipping lunch. any way i got he thing welded and assembled just in time! but no chance to start it up (although i did ride down some hills with the chain removed).
i have a feeling the super low gearing (about 9.6:1) will make push starting very challenging, i will either have to:
1.do nothing because it is very easy to push start
2. have to change the gear ratio.
3. install either kick, electric, or recoil start.
out of those options, i would LOVE a kick start! fit the vintage style perfectly!
and just to clear up any confusion, when i say i feel th engine will be hard to start, i mean it will put up a lot of resistance while starting, not that the engine wont run.
homemade:
sprocket hub
frame and forks
seat
fuel tank (non leaking) with a gas cap made from a 1 1/4" pipe cap.
exhaust adapter.
probably some other stuff i forgot too.
any way, pics!
p.s. i learned the hard way that #41 and #415 chain have different pin diameters. i bought a #41 half link for the mini, and a #40 half link for the kart, after finding out that the #41 half link pin didn't fit in the #415 chain (even though it says it should
here.... no that i think about it again the #41 would also have been too wide to fit the #415 chain). anyhow, i used the roller and bushing from the #415 chain, the side plates from the #40 half link, and the pin with cotter pin from the #41 half link, all taken apart, and hammered and pressed into a homemade #415 half link! sorry if all that is a bit confusing
