Recently moved myself and my 2014 Sportsman 400 from Kansas to 9,000 feet in Colorado. She’s running pretty bad. I don’t mind some loss of power but I’m getting no response beyond about 50% throttle. I tried a few easy changes to no avail.

Called the local Polaris dealer and they said I need to install a new main jet and three new clutch weights. I plan on installing the $6 main jet but do I really need to install the clutch weights? I’ve seen others say it isn’t necessary but wanted to get your opinions. Thanks in advance.
