I recently bought a Kodiak 400 4x4. It was a fixer upper. It had no carburetor on it. I could only find one used OEM carb. It was $120 and in HORRIBLE shape. So I bought a Chinese carb. It took some tweeking, but now it fires right up and idles beautifully. I take off and it takes forever to get to the top end of third gear. In fourth gear, it never gets to the top end. I tried a #120 high speed jet, and when I choke it, it bogs down more. I tried a #115 and get the same result. I went ahead and ordered a set of stock size jets. Anybody have any experience with these bikes? Any ideas as to what's wrong?

 

Will it rev up in netural? if not take air filter off an lift slide up slowly with finger see if it helps then hollar back here

 

Yes, in neutral it will rev up without messing with the airbox. I did try a test run without the airbox lid or seat, it still ran the same.

 

I have been waiting on parts and they finally arrived. I was wrong previously. The bike doesn't rev wide open in neutral. I'm at a loss.
