Please - you don't give it gas to accelerate - you give it air - as you open the throttle, it's the job of the carburetor to mix the correct amount of fuel with the air to support combustion. Ideally, 1 part of gas to 12.5 parts of air. At 14:1 it is lean and the engine produces excellent power, but runs hot. At 12:1, it is rich and while runs well, it wastes fuel.

Most bogging (if not an ignition or compression issue) is caused by too little fuel being mixed with the incoming air. What I do not know is if you have made any modifications to either the exhaust or intake. Just installing a different air filter is a modification and modifications to the intake affect carburetion immensely while changes to the exhaust have a lesser effect on the carburetor settings.

You may just need a thorough carburetor cleaning not just the jets - the passages within the carb must pass air as well as fuel.

2014 trx 400 ex rough idle and bogs down around 1650 rpm (under throttle) Solved

Solved! I went again and cleaned my carb . And I noticed the throttle slide piston was stuck as if the throttle was fully engaged I messed around with it and added carb cleaner and kept opening and closing it till I notice it wasn't getting stuck. In conclusion, the reason it was stuck was because I would leave fuel in my carb. Hope this helps any one else.
