if I'm running around 50 or 60 miles per hour for a bit and go to crack the throttle it will just bog and not accelerate but if I let off the throttle and then punch it I can get over100 MPH

Sounds like your flooding the engine. Could be your jetting is wrong, and your carbs could be not adjusted properly for the idle. But they could also be dirty and need cleaning.

I know you said it was fogged, but that doesn't mean your carbs can not be dirty or have a clogged passage or your float sticking causing it to flood the engine and cause the bogging.

To me it sounds like a carb issue.

Try turning the air screws in 1/8 of a turn at a time to see if you can get the idle to come down. That will also help with a low end bog.

If you turn the air screws all the way in (1/8 turn at a time) with no change, that indicates the air or fuel passages to the pilot jets are clogged. That's very common and a good reason to clean the carbs yearly just prior to the start of the season. With the garbage gas we get these days, it's a wonder sleds run at all

Idle should be 1800-1900rpm. Good luck!
