So I have a 2014 M8000. This is the second one I have owned and both sleds have done this issue I’m wondering about. some times it won’t rev up past 6-7000 rpm. Sometimes it’s even lower. It might do this about once every 50 miles maybe. Machine has good fuel In it. Has some heat in the fuel also to help with moisture. I’m wondering if I’m the only one that has been coming across this and not sure what else to look at. Thanks for any help.
