Does any one know if I should go to a bigger main jet or change my needle settings to richen it up a bit?

For a stock bike in cold weather I'd bump the main up one to a 165 main jet with an adjustable needle. The stock pilot is actually ok (and I know some people who run the stock pilot jet on their modded bikes successfully) just get an adjustable aftermarket fuelscrew so you can tune it.

Ya know, just to raise some controversy, it seems that many on here, including me, were able to dial in their jetting without the $75 JD kit. I seem to read just as many posts from those that weren't able to make it work as those that did.
I did the JD kit because I didn't want to hassle with tuning (carb access). You literally drop it in per the instructions and its ready to roll.
Knowing what I know now about what works and don't work in these bikes, I'd just buy the jets I need individually and save $50.
