Hi all hoping someone can help I have a 2021 se 300 factory it is now on 70hrs! It has just started to develop a fault with what seems to be an intermittent power band sometimes it kicks in then sometimes it don’t not sure if it is getting stuck closed or there is a electrical fault?
Would appreciate any advice.
Cheers

If the 2021 power valve is anything like my 2016, you will propably have to clean the potentiometer inside the pw servo motor. My 2016 se has had the same problem and it was because the potentiometer was dirty. Today was the second time I had to clean it, before cleaning the power valve didn't open when riding.

It's an easy job, remove tank and the power valve servo motor, open it up and you will see the potentiometer. Spray some electrical cleaner of the shaft and turn it around, make sure the cleaner gets inside of it.

If you play electric guitar you know that pots get easily "scratchy" and won't work properly untill you clean them. Hope this helps. Power valve problems are really annoying.

Did you figure out your problem? My power valve isn’t opening.
