Check out www.koaseries.com for updated rules. The download version will be updated shortly.
1. L206 Sr Champ will follow briggs rules.
A. Unaltered stock spark plug
B. Open clutch rule
C. Open air filter. Filter must be attached directly to the carb.
2. Heavy clone
A. Koa will follow pomfret pipe rule. My wording could be wrong but I believe its going to be max 14.5" from floor to bottom of silencer, Min 10" long. This rule is for the safety of the racers and not have a pipe head straight up and down.
