Hi:
My first build was a walmart purchased schwinn landmark 7 speed, the last one they had.
And a two stroke kit purchased from bikebarry.com,the black stallion 66/80cc kit.
Had to fabricate a few parts for the mount and chain tensioner.
Which is getting better but am having a hard time getting the sprocket centered on the hub.
So far around 250 miles on the bike runs pretty good but still needs some fine tuning.
