Hello,
Recently I have noticed that when my son Adam is getting almost near the end of the main straight away his rotax motor seems to be making a sound similar to a limiter or govener (motor has reached its highest rev and is missing or hesitating to rev higher). Is this sound normal for a junior max (without a power valve)? Or is there a problem here? I am wondering if it could be the copper sealant used to seal the exhaust flange on the motor to the pipe (the point where the springs hold the muffler onto the motor) needs to be re-applied?
Much Thanks
Dean Krumes

Re: Unknown Rotax Engine Sound
What RPM is he hitting there? Is it a popping sound?

Re: Unknown Rotax Engine Sound
Thank you for the replies and sorry for my late response (I had to check his Mychron, see image below). He is running 11/80 gears. He does not presently have an EVO upgrade installed (I have one for him, just have not installed it yet). I will check his jet size and post soon.
Any help would be much appreciated.
