There is a simple test you can conduct for the irratic running you are experiencing, its called the "choke" or "power inricher"

While the engine is running irratically, pull the choke 1 knotch.
If that helps, or fixes it, it is suffering from a lean fuel condition in the low to midrange throttle position, same as many of these bikes suffer from.
As said above, the white spacer mod usually fixes this problem very well.
I know it fixed mine.

When did you buy your bike and with what mileage? I have wondered if the petcock may be an issue already. Thanks for your input.

So just another question regarding setting stock petcock to Prime. Other than not having a reserve, I won't flood the carburetor or do any kind of damage to the bike running it completely on prime for a couple of days or longer? I religiously watch my mileage so it never gets to reserve other than the twice it's happened. First time literally two blocks from the stealership I stalled out and had to switch to reserve...nice shock...not impressed and no apology or concern from the place I bought it. Second time I was purposely trying to see how far I could get on gas before needing reserve. Both times it took a bit of cranking to get the bike fired up again. Thanks for the advice and help.

Well they sound similar anyway...when I first got the bike (owned it maybe 2 weeks) it ran great...as the weather started to cool around here I began riding to work and in the mornings I would notice it starting to stumble and lurch a little.
The first couple times I rolled up to a light and rolled off the throttle it would just die...I'd fire it back up and it would get me to work but I found myself feathering the throttle whenever I came to a light.
When I would leave work the temperature was warmer and the bike ran great.
did this for about a week...got fed up, ordered the raptor (my very first mod) and it has never happened again... it was a cheap easy fix and wasn't going to hurt anything so why not?

Ran fairly well till it got cold out side. Then I discovered the fuel screw was only turned out 1 & 1/2 turns. Turning it out to 2 & 1/2 turns really helped. Of course I re jetted later and added a raptor.
