In reference to the 116s, yes, wahls used them, Jacques used them, pj used them, and I still use them. They will go an entire season. The 13.5"x116 weighs one or two pounds more then the 106.
i like it except the camoplast 13.5' track is not anymore expensive then the 15". i'm not sure letting us use bigger carbs is a good idea either, seems like speeds would increase.
What about limiting front end offset? It would help with loss of control in turning right and make them less aggressive turning left. Just throwing it out there as I agree that something needs to be done.
