hesitation when pressing throttle

I have a 2018 outlander xt and it has about 200 miles on it with 24 hours. When idle or going pretty slow (under 10 mph) when I press down decently hard on the throttle theres a slight hesitation like about a second until it feels like it gives it much gas. It still speeds up during that second but definitely slower than usual and then it feels like it get all the gas. I replaced the spark plugs and put in seafoam and I think the seafoam made a slight difference but it’s too hard to tell. The air filter doesn’t look dirty but I ordered a new one anyways just in case. I also took the drain plug out of the belt box and no water came out. All of this happened after I took it mudding and then power washed it. This is also my first bike so I don’t know too much about maintenance stuff. Is this something small I can fix, or should I take it to a mechanic
