"My engine bogs down every so often. I could be moving at 30MPH and it just dies out, then comes back. It's like it's flooding itself but it idles fine and the plugs are good. Any ideas? Thanks"

is this motor carb or injected? if carbs then they need a good cleaning. i just went had this problem. they need to be taken apart and cleaned good not with the spray cans or the stuff that you put in the gas. hope this helps
