Thank you Angie, I appreciate it.
Will there be any changes to the ICC pro shifter set up from last year? I know the class has has been combined with moto motors, but other than that, what are the motor limits and weights for the ICC package? CSC and club differences?Thanks again in advance.
Is the year of the cylinder still up for discussion? I thought the supply of ’99 cylinders ran out in June or so. Did someone find a bunch or start making them again? If not, we should seriously consider opening this up to ’99-’02.
Kurt, I spoke with Dave Larson today, and he said that availability is not going to be an issue. He said he has been watching the situation closely, and has determined that sticking with 99 is the best, and there won’t be a problem with supply. You can reach Dave at 866-489-3283 if you want to know more.
Curt, I am double checking, but don’t think there is anything to be changed in the 125 shifter class. It is the same rules that were for the Pro and/or Novice 125 class in 06. Was there something in particular that you were concerned about?
Thanks!!
angie
:loony:Cylinders are in stock. I ordered one from Service Honda last week and it arrived this week. Kit engines are readily available. I talked with Extream Motorsports yesterday and they have quit a few in stock.
