I have a 2004 Polaris sportsman 400 and when driving it sounds like its on the rev limiter but it only at 4300RPMS, when you kinda pedal the throttle per say it will kinda get to almost 5200rpm but low on power and usually will drop back down to about 4300rpm. When the ATV is in neutral it will rev up to 6300RPM no check engine light on or anything in the speedometer. When i first looked at it I did a compression test found it was low rebuilt the top end had new valves and camshaft, cleaned the carburetor, put new spark plugs and fuel filter, new air filter, reran it after it was rebuilt same thing, I've ohmed the ignition coil plug wires and pulse coil everything ohmed out fine according to there specs, drained all the old gas, it shows the correct gear it is in when shifting tried disconnecting that see if it made a difference nothing, checked throttle safty shut down it works properly. It also has fairly new drive belt i had extra one swapped it over still same thing. This ones got mew stumped on what else to check
Note: the problem just all happened right away was running good and then just started doing this
