RE: AME engine mod's for racing
I hear you about guys not wanting to change what really is a pretty good thing right now. But a guy could race with just one CYCLON for years, instead of having bins full of NORVEL parts and no less than 2 strong running AMEs ready at all times. If the Norvel and VA diehards were honest, I'll bet most of them have enough junk P/L sets lying around to buy a CYCLON with.
As long as the AME is still available, there's not much point in rocking the boat in your club. If Norvel was to quit making small engines, I wouldn't expect the supply of engines in new condition that are for sale on auction sites to be as deep as COX engines has been.
