I am new to the forum but i have a schwinn chopper with a engine kit from gasbikes.net and i just put my new chain on yesterday and went for a couple mile ride and when i went to go on it today, when i released the clutch lever to start it, nothing happened. The clutch wouldnt catch or something therfore it wouldnt start the bike. Also when i just simply push the bike the back tire doesnt lock like it used to when the clutch worked. Any ideas? Thank you.
