I have a kodiak 400 that won’t rev up in neutral or in gear!! When I bought it it sat for a year with gas in it so everything was gunked up, I cleaned carb thoroughly and put a carb kit in and the bike will now idle decently but when I hit the throttle it’s almost like a rev limiter, will rev to what I would say is 1/4 then hesitate for a second then get a tad bit higher but won’t rev out. When you try and drive it it just won’t go over 10 mph. When I first got it and tried starting it up we got it started and it was revving up like it was supposed to but ran badly because of a dirty carb and then it just stopped after a while? I noticed the oil level was low too and I know it has a leak somewhere down bottom but would too low of an oil level cause it to do that?
