I just got a reasonable deal on a 7spd Schwinn cruiser and ordered a four stroke kit from Gasbike. The under two hundred dollars for a four stroke kit was too much to resist. I've got 50 miles on the two cycle build now, trouble free so far after the initial wheel lock up. I'm hoping the new engine will show up in a few days and I can get this bike running to play with while I tear down the original build for painting and dressing up a bit.
