How cheap?!? Because unless you want a Thunder Tiger mill or similar, you are looking at over 200.00 for the next step up. The OFNA/Picco 26 MAX is not bad one.
Go on ebay and look at the sirio s27tx. For 159 bucks you'll have a 27, with a mount and header. Your pullstart/ez start will work too. The header is bb sized so you'll have to adapt to your pipe or get a new one. Also you might have to mess with the throttle linkage a bit but it's well worth it for the money. IMO it's the best deal anywhere.
