Understanding the Mid-Range circuit VERY IMPORTANT ARTICLE!

 

One of the easiest way to burn up a piston is by not understanding how the Mid-Range circuit of a two-stroke works. Please take the time to read this article and understand what it is saying and how to apply it the operation of your engine. In a nutshell: Don't pull the power back to 4000-5000 rpm and unload the engine by starting a slow descent like you would with a traditional engine. Your EGT's will quickly exceed the redline of 1200 degrees.

There are two mistakes a pilot often makes after an  engine quits. First it quit for a good reason. Don't try and restart it. You'll likely destroy the evidence that made it quit. Second don't automatically blame the engine for your troubles. The majority of Rotax engine stoppages are due to a fuel starvation issue.

 

This article is another great troubleshooting source.
