Having a bogging problem. PLZ HELP!!

[Nathan420]

So my Yamaha blaster starts and rides fine but when I try to hit a burm it starts to bog out then starts to accelerate again when I come out of it. Same for if I’m trying to do a donut. I have no bogging problem going straight, only bogs is under pressure

Did this problem suddenly start?
Clean your fuel system. In tank filter, petcock, carburetor. Set float height. Record jet sizes and needle position when you have it apart.
Pull emulsion tube/main jet holder and clean side holes. Make sure main jet washer and slosh baffle are in place
Clean your air filter too
