Hi, I recently bought an 04 trx450r and it had a really bad bog/hesitation on the low/mid range, it felt like a turbo lag. When I hit the gas is barely went anywhere and then took off and really pulled hard. So we drained the gas (which was pretty bad) and threw in a 130 main jet and it helped a lot but there’s still a slight low end bog but it picks up pretty quick. I’m not sure what to do now. Leak jet? Needle? Air fuel screw? The carb is brand new and put on by the previous owner as far as I know all jets are factory besides the 130 we put in. Stock exhaust, k&n filter with the lid on. Any help would be awesome!
