Not been able to do much. (See pics) Test ridding new 50 T early this week, Awesome! Low, mid range is slow to get going but tops out around 4K RPM. Just hums along at 34 MPH (guessing, speedo keeps freaking out and GPS batt dies real fast in the cold) At that RPM and with the rubber muffler, I keep thinking the thousands of hrs and dollars spent and I successfully built a scooter by the sound, snork. I might try the 52T rear but think I am close to actually being done with this build. Is a cheap build but exactly and I mean exactly the motorized bicycle I saw in my head when I first saw an add for motorized bicycle kits just a few yrs back and is my personal favorite, bar none. Pales by comparison to the works of art I have seen here. Cheap kmart bicycle and a $100 engine but man, she is purty! Eye of the beholder and proud Poppa sort of thing I guess.
Factory space might have fallen threw. (the deal, not the actual space)
