Re: Hi All
From what you've said, I'd follow Nash Kat's advice and just go with a new kit. Another option would be to buy just an engine (less the other kit stuff). An engine alone costs about half that of a full kit and a CDI unit runs about $25 or so. This, and catching a sale (like you say) might get you what you need for ~ $100 less shipping.
As for shipping, you'll want to shop around when ordering motorized bicycle stuff (especially smaller items). Some retailers charge higher ship rates in order to make up for their "bargain" prices. These shipping costs can, of course, $10 and $20 you to death.
