I see you've edited your first post. ... Better to start on a new line with "EDIT: ..." or explain in a fresh post.
Anyway, so it's not a WOT (mains) problem. If you're backing off the throttle for your cruising speed, then it's more likely a jet needle issue (1/4 - 3/4 throttle). ... Try moving the needle to a richer setting - moving the clip down from 3rd from blunt to 4th from blunt.
It does sound like fuel starvation as others have said. ... You could check your float levels.
The factory doesn't jet for removal of the snorkel, so it might be wise to go up one or two sizes on your mains.
Rare.

Thats kinda what i thought when i would stop shut it off and then in a minute or less it would start right back up and be fine. Do you think that if i get a k an n filter lid for the air box of course that will come with the correct jetting that this will resolve my problems. Before i do this ill try your idea with moving the clip from the third to fourth. Thanks alot
