Im at the start of doing some mods to my RXP. All the information here is great and helpful but my head is beginning to spin. My thoughts are start with the Riva Level One without the wedge and later come back with the Rotax Stage One setup. Then go with the rear exhaust setup.
Question: What would be the results to a stock RXP ski with only the RR Stock ECU. Pros & Cons? Thanks for your help and when I get started Jerry will get my busniess.
