Since the throttle adjustment screw is easily accessible, I took the opportunity to play around with it while I was out riding last. It didn't seem to fix the issue Will do, thanks!

My Dad rode it and suggested it was the float, haven't heard anything else from him but I don't quite know for sure yet. First off, yes, the problem is in the mid range of the throttle. Going uphill, throttle dumping it seems to be the only way to receive the power I need at those demanding moments while going uphill. However, towards your second point of it being the floater; I have a trailer that the quad towed just fine at all throttle ranges from 1st to 2nd gear on level ground but those gears never lose power on graded terrain so it's not definitive that its the floater yet. I have about a 300 yard straightaway, I should probably get to those upper gears with the trailer (load on flat ground) and see if that does it. I will get back to you on the results of this little test.

Never throwing an OEM part away again, bummed out I learned the hard way. Thanks, I will definitely look into the Mikuni carbs

Hey all! I recently acquired an 02 big bear 400 this past summer, carb on it was shot to sh** (pics attached) so my father recommended I just buy a new one off amazon. I purchased the first one that came up as compatible and once it came in, I bolted it in and it fired right up with no noticeable issues. Once I got to the trails with it I realized that on any un-level ground, there's little power output. I checked with 3 different local shops and they all refused to work on tuning up off brand carbs because of how terrible they are. One shop had a motorcycle in with an aftermarket carb and the mechanic said that that would be me if I brought my big bear in. Whoever owned the motorcycle and needed their aftermarket carb tuned up had racked up the bill to nearly $1500. Needless to say he made it clearly obvious that putting any amount of money into an aftermarket carb is not worth it. Now that I've learned all of this, I'm wishing I didn't toss the old carb for a $30 amazon one. In light of this minor f-up does anybody have any recommendations for high quality carbs for my vehicle? I've also attached pictures of the old carb and its condition for your curiosity, although its current condition is likely 6 feet under in a landfill somewhere. https://www.ebay.com/itm/283488113569?_skw=Big+Bear+400+Carburetor+Oem&epid=10042848409&itmmeta=01JCDWCTMJX5GBC407RF2PPVDD&hash=item42013553a1:g:INUAAOSwn8llquIL&itmprp=enc%3AAQAJAAABAHoV3kP08IDx%2BKZ9MfhVJKkIMhqd%2Fye0vA0YMR5DUzMoCLl0F9GPNRfuAJKaylVqqyVrZCBJVvXQaPrlosjt%2FZnIHyIRPuGiIbxC9o%2B02UqGA4YqXDyyH4bVebnTPz8P5Elg76CvLdu3KyZgwpgpSeYJK2IOWtlo9vtTld7RVjqPwSv1VF26v6kyXGesAB%2BA%2BCHsj3OnqNrHMyKCBuDMSSvUWvOfq%2BKsZKqyHR7yduef%2BHBlXvfiyRJPThHr7Ge9n%2BHBbuxRCb4oF7%2Fp8oZsvajHy9YDitFRfNJeeAssYbgXuhAc7AVvUZZ2YxKW9GzDdxltLMap8orKJtr%2BIk0SRGQ%3D|tkp%3ABFBMsqqzvONk I found this one on EBAY that advertises as a genuine OEM part for a fraction of the $650 that they're normally worth. Any help would be greatly appreciated, thanks!
