Running the new Italian Motors X125 TaG motor in the Pacific NW (SIMA race track and IKF Region 6 Gold Cup). The latent engineer in me fell in love with the motor even though it is not yet accepted on a national level.
Regarding the TaG fragmentation, I don’t think we can analogize to snowmobiles (or motocross) because those sports have far better spectator and TV appeal. Because of their scale and relatively low top speed, karts do not make for good TV or spectator attendance. Therefore, the only only money in karting is from selling product and from entry fees, which is a pretty small kitty. We’re seeing a relatively natural evolution in which competitors are attempting to maximize their slice of the pie in a sport in which there is no common, shareable revenue like TV dollars.
