It official WKA will run Yamaha's again this year. Same rule package. Hope to see some interest here on this thread and maybe even a bit of smack talk. Anyone ready to get it started. LOL

John,

Rule package? We go by OSP rules I believe! Tech. Good question.
Approved stock appearing as I know it is the following:

Up to 55 mm piston
No strokers
No reeds
Gas or Methanol only
Walbro wb3-a carburator
Stock rod
390# minimum
