Reliability is great and a true 100 hrs between service if it is driven according to the manual and even then, the service is not much. Mine is over with Richard being serviced right now. The aixro only has two issues, one if it is over revved and it’s a costly mistake. All the new ones come with a PVL ignition with a rev limiter, so over revving it is taken out of the equation. The second issue is if you run it at WOT for more than 10-12 seconds, but that’s never been an issue for me either. It is an engine for kart tracks, not road courses.
