wont run right at mid to full throttle
After checking the easy stuff, Check the cam exchaust lope. They are known to wear down. It sounds just like my neighbor's and that what was wrong with his. Yes, it can happen all at once. Do a search for sportmans rough running and cam and you'll find that yours is acting just like there's did and they found the cam warn down.

its a 400 4 stroke with about 210 hours on it. how does a guy go about checking the cam, i dont know too much about small engines (but i get buy). do i look through the top cover or the side cover on the right side?? before i start ripping apart the motor i'm going to check the plug wire for cracks and wear.

checked out the spark plug wire and that looks good, the vent lines are clear. i run it today until it got warm then a gave it full throttle for about 10 to 15 seconds, then i pulled the plug and it was a little black (it was a brand new one a couple days ago) i'm thinking that it maybe a bigger problem than i expected, i might have to get a new cam for it
