The engine is on a Polaris Razor 1000 XP. Polaris uses Twin Star engines. This one is a 110 HP fuel injected.
The Silent Hektik and the John Deere regulator are two I have heard of people using. I know nothing about them and I'm not sure how they will hold up. These guys are experimenting and it may or may not turn out so well in the long run.

Over a 10 year period I have invested in 5 of those 'pieces of junk'. I eventually bought an Australian designed and manufactured regulator which unfortunately is no longer made. In fitting it I relocated the unit from the hot engine bay (aircraft manufacturers choice) to a cool spot inside the cockpit, adjacent to the ventilator. Since this change I have had no sign of a problem. If your regulator is in a warm spot, give some consideration to moving it and while I am at it, is anyone interested in 5 little used Ducati regulators. I notice that they are no longer fitted to their motorcycles!
Regulator failures aren't usually the regulator's fault. Sure there is a bad one now and then. Rotax isn't the only one that uses these and evidently all the others aren't failing. Poor location with exposure to too much heat, too little voltage draw or too much voltage draw causes excessive internal heat. Bad wiring setups cause issues too.
If you are having constant issues I wouldn't think it's the regulators fault especially if it is in the same model plane.
Try ruling out heat first. Use some heat temp indicator strips on the side of the regulator. Mine has never been over 140F. Location is everything. Vans had issues on the RV12 with their location and heat. Now they have approved in in cockpit location. Add up all your voltage using equipment and see if you are too close or over peak output. I work on many 912's every year and none of them have regulator issues, but the system was well planned out.
