I’ve been to the track three times over the past week and I have to say the EVO updated Rotax is awesome. Still running the old 2004 motor updated to EVO and the performance difference is night and day. I know they say the EVO kit doesn’t present a performance increase, but my 04 engine is a BEAST now. Real usable power from 7,000 rpm on. I’ve been dropping gears sizes and the motor just keeps pulling off the hairpin and the top speed gets faster.
I’m really blown away by just how good my 04 motor is now. Its significantly stronger than its ever been and requires a very different approach to driving the course. It used to be I eased into the throttle to prevent the engine from bogging. Now I ease into the throttle to prevent the rear wheels from spinning.
