I have a slight problem! I thought that the sprockets on the engine side took # 41 chain, not so too wide. I have a very steer hill leaving my house and when it had to pull hard it threw the chain. Tighter didn't help. I swapped it out for a very used single speed chain and it skips under heavy load. Neither of the two bike shops in town have that size chain. Tomorrow I will head to Walmart or Kmart and see if I can find a new chain. The bike pulls strong uphill. If I can solve this chain problem I will have a winner!
