First post so be easy on me. Last July I bought a used Margay brava 1.7. It came with a non-Evo Rotax with “20” hours on it. I got to go out for 3x30 min sessions at the local track with it, and besides some miss firing on the last outing has been “ok”. I have tried to do alot the work myself so far. Rebuilt the caliper, and master cylinder, rebuilt the fuel pump, changed out both rear cassette bearings. Rebuilt/reworked the carb.
My plan was to have the Rotax freshened up from our local karting place here in WA, or just buy a whole new Rotax SR EVO setup. But the more I read, the more it seems people are going to the X30, or the ROK (first read about it today actually). I understand being 35 years old I am not going to go out in my first season and Verstappen it up, but having the equipment to be competitive if the skill set should rise wouldn’t be a bad thing either.
Would it be better to just have my motor rebuilt, and add the EVO upgrades, or switch engines now? Thanks for listening, and for any advise.
