These mopeds are great mopeds. I own one and soon I'll be getting another one. Handy bikes is an excellent source for parts. Prices are reasonable and they're NOS.
Which engine is on that moped? These came with the option of two different engines. The Solo, and the Sachs. The Sachs has a long exhaust pipe. The Solo has a weird looking alumnium exhaust that doesn't extend past the pedals. Either way, its a good moped. But if it has a Solo motor, these are awesome engines.
If it does have the solo motor, I can help you out with sources and stuff related to repairs. I'm pretty familiar with these engines.
