well...technically Honda's stock piston is a Wiseco piston....but does anyone know if you can get that from honda right now or if it is one of the banned parts? I know someone couldn't even get a throttle tube because it was the same p/n as a Honda 50, had to go aftermarket. I have a call in to one of my distributors at the shop but haven't heard back yet.

GUYS....
motor has to be Stock 49cc (using stock Parts) its ok to modify the stock parts
anyone using a stroker crank kit or aftermarket Pistons, cylinders or Heads (like last year) should stay home. its not going to meet the rules this year.
there is plenty of ways to tweek your stock parts and still be legal to race the class...
why not just leave the PoorBoy and Limited Classes motors 100% stock... as thats what You guys asked for STOCK CLASSES
