So if itís using slot of gas and bogging, has a good carb, I might look @ a few things.
First is choke. My 2011 and 2012 500 Sporty has a choke pull on the left side of the main cluster head. Examine your carb to see if itís fully choking and unchoking manually.
Check your spark plug to see if itís burning clean.
Fuel. Contaminated fuel by way of ethanol damages lines and carbs and gathers up gunk in your carb bowl and fuel pump which can restrict gas overall flow. I might be inclined to think this is really and is mostly the issue. Corn in the gas is a killer. I use REC gas and Seafoam the last few years and am getting better performance.
Lastly, a bad battery under load causes this bike to stutter like hellllllllllll. Iíve had this happen.
So youíve got an array of things to check. You didnít say backfiring or did you ? Mine was backfiring, strictly gas related that Seafoam fixed.
