Rear sprocket and EPA questions
I have spent the last few days reading and searching the forums and have a couple questions...
It seems all the kits have rear sprockets that bolt/clamp onto the spokes. Does this cause trouble? Is there a more elegant solution? (Maybe something like a flip/flop hub?)
On the two cycles, is a catalytic muffler the only change that makes them EPA certified? Is the seller's promise the only way to know if the engine is certified?
I would prefer a four cycle (cleaner and no mixing) but the ones I have seen all look like weedeaters. Any suggestions?
