today I noticed that when my bike is on natural and I try to accelerate it wont do it right on low rpm's between 11/2k to like 4k in that range is sounds like it wants to die its shocking. That's when you open the throttle quick seems like very slow response. But then after 4k it works fine quick response to the throttle when you try accelerating. Please let me know what can it be, i recently drilled wholes inside my exhaust for now till i get aftermarket i dont know if thats the case or not.

Thats how the bike is. Its a dog at low RPM's. Mine does the same exact thing. If the want it faster off the line, then a PCIII will smooth it out and remove the bogging down.

Has the bike been in storage? Fuel stabilizer in the tank? It shouldn't have any hesitations with or without a PCIII. Rev's should be smooth and stumble free.

Plugs could also be a culprit here. It also sounds like you might be running lean for some reason too: Faulty PCIII, PCIII map, fuel pres. reg., dirty injectors, air leak, etc ...

Before it wasnt like this, i never noticed it. the other guy caboarder said its normal his is the same way its wiered. now im all confused. It seems ok when i ride just on the natural when the bake is not moving. Can someone check on their bike see if it does it or not??? try accelorating open the throttle qucik all the way and see if its chokes at the beginning between 1500rpm and 4000rpm.

i only have 2500 miles on it i dont think air filter or spark plugs can go bad so quick.

He's referring to the powerband of the bike. Not the performance. It's NOT normal to stumble. If you want help answer some basic questions so we can start to get a better picture and eliminate some things.

I think i know what you are talkin about now and its normal. Your sayin you are just barely putting along at 1500 RPM's and then hit the throttle wide open? Its normal for the bike to be sluggish here because it has no power down this low in the power band and you are just puttin a ton of load on it opening the throttle wide open dumping a ton of gas and air into those cylinders.

Got the diagnostics back from the shop, your not going to believe this.

GAS CAP!

he check the pump and it checked it out good.

he check the air filter and it checked it out good.

during this process he checked all fuel related items, but then he though.

"Let me take off the gas cap and change it with a new one"

bingo! bike does not chock.

he mentioned to me that the gas cap was not releasing pressure when you opened the tank cap, the non-pressure release caused the fuel pump to have issue at high load (reeving 5k RPM +) after you where on it.
