This point of view comes from me, Jim Keesling kart racer.
The whole problem with the “seal” is Rotax drivers WANTING (Needing) to race two series.
One series requires a seal, one does not.
I have torn my stock motor down 3 times now, and have put it back together. That’s one of the costs of RACING.
We are in a rock and a hard spot. We have a lot of Rotax motors here in Colorado, and I know you all want to race the two very different series.
At some point in time, the driver needs to decide which is more important.
See you all in Steamboat,
Jim
