Reply To: Jansen destroys Rotax in record time?

Brad is correct about dirt and Rotax motors. I learned the hard way a couple of years ago by ruining a motor by getting off track and sucking a bunch of dirt through the filter. If I get seriously off track now, I immediately shut the motor off and don’t even drive it back to the pits. I keep a spare clean filter foam so I can swap it quickly and be ready to go again.
