Bogging down issuse

So for two days now my bike has been giving me a bogging issuse. When I barely open the throttle is moves slowly with very little hesitation. Open the throttle about halfway and it Boggs down completely loseing RPMS. Open the throttle all the way and it wants to do a wheelie. Any ideas???

Sounds like you've got a sticky float to me. You are getting too much gas until you are getting the right amount of gas and air at open throttle.

Yeah I've used two cans of tecron carb cleaner and one can of sea foam and still no better. What should my next step be?

Also I was wondering if a vacuum leak would cause those symptoms?

An air leak would cause a lean mixture, you'd get popping and backfires usually.
"Bogging" can be caused by a too rich mixture. If you can get it to idle...spray some WD40 on the carb boots...if the rpms change, you got a leak.

I'd check both of the diaphragms in the carbs for tears or holes...

You've taken off the bowls and sprayed that **** in there?

Cause at slow speed or just taken off you are on the pilot jet.

Drain the fuel bowls, then get some seafoam or Berryman's B12 and pour it into the carb vent hose. That hose leads directly down into the bowls. Let the cleaner sit (B12 - 1-2 hours. Seafoam - overnight) Then drain the cleaner from the bowls, maybe even flush some fresh cleaner in as you let the bowls drain out. I know that helped get a LOT of sediment out of my carbs when I first got it.

Sorry, was working at the beach and rode my faster than light sporty down and back. Any carb cleaner spray will do. I wish someone would fabricate and sell a cv carb splitter so these bikes could just run on the one carb like the sportster. I bet most of the problems we see here would be solved.
