Okay experts...my 2007 Wolvy will start and idle like a champ, but it will not accelerate, especially if you open it up. Sputtering, popping, hardly ever stalls(but has), WILL NOT PERFORM. I cleaned filter, still doing the same thing. Can't be the gas because my Honda isn't doing the same thing with the same gas (although it is a Honda LOL).
Is it a dirty carb? Checked the carb vent line...clean. Gas cap vent line clean also.
Still under warranty...trying to decide if I need to take it in or should I expect them to try and rape me if it's only a dirty carb? I also have a service plan with them...routine maintenance included, not sure if dirty carbs are covered.
Any ideas what I should look for to fix this myself?
Thanks!

 

its prob the belt bro, i had the same issue but it did accelerate but did not have the torque is use to have... Have you ran it thru deep water? I had water and dirt on my belt and caused it to slip and not go near as fast. I took mine to the dealership easy fix. Costed me 100$

 

If it was the belt, would it still sputter? Or would the engine still rev up, but no acceleration? Mine is not reving up...don't feel any slippage.

 

Like when u pull the throttle it doesn't rev?

 

It would rev in neutral, but not in gear, forward or reverse, didn't matter, would sputter if you hit the throttle pretty good. It seemed like a dirty carb or air issue. After cleaning carb today, I cleaned all of the vent lines around the carb as well. One of them was not blocked, but restricted. As soon as I got it cleaned out, it ran like a champ again.
I hope this helps someone in the future.

 

Great, im glad you got your issue resolved. Sorry i wasnt any help.
