Isn’t this is an “outlaw” type of deal. I really really don’t care one bit what TaG USA does. Seems like it’s just a deal to sell motors anyhow.
You’re going to kill the Rotax if you go with “what comes in the box”. Unfortunately given that two of the track owners support motors other than Rotax, they may not have a lot of motivation to help out the Rotax anyhow. My point is that the Rotax program is all about slightly de-tuning the motor as a trade off for longer life and less maintaince. Those Sonic’s motors can go like hell at 15,000 +RPM, but they won’t last long, and the electronic ignition on my Rotax doesn’t let me get about 11,000. The easiest and cheapest mods on the Rotax are the K22 needle and a less restrictive air filter. Let’s forget about a “CIK airbox”, do we really need to worry about the noise factor? We won’t be louder than the shifters. Lets just go with open air filter and use an easier to use shifter type airfilter.
It probably doesn’t really matter anyways, the 15,000, 1 hour Sonic’s will probably be the dominant motor next season. Or at least until they come up on traffic!
