Thanks for responding Dan. I understand clearly the spec meaning now. I was thinking hp restrictions or restrictors of some sort. I just see a bright future with tag and I wish to see the sport grow. I honestly would like to see and hear different engine makes; like in IMSA. As for stock Honda or shifters, I would like to see a stock Kawasaki, KTM, Suzuki and Yamaha in the mix like moto x. It just seems like more money and sponsors for the sport. Just a thought!
