i have a couple questions about jetting

[yamaha driver]

first of my mods are only fmf pipes with no airbox just open uni airfilter.

 

so right now my plugs are about a tan color after just riding around. but it seems somewhat hard to start now since it got a little colder out side. it takes full choke and about 8 kicks at about 20-50 degrees. my jets now are 25 pilots and 250 main's and my needle is on the very lowest setting. i believe the needles are 5n7. and air screws are out 2 screws. Should i jet up? and if so where is a good place to buy needles and jets since one of my needles are bent at the tip

[yamaha driver]

anyone know where i can pick some jets and needles up?

Jetsrus.com I've used in the past

Do you mean the tips of your plugs are tan, or a tan ring with the threads chopped off?

 

And if you've been riding in the summer months in MN, then you'll definitely want to jet up for Winter.

 

If you don't have it already, go and download the Banshee Digital Toolkit,

and use the jetting calc. to help you get your jetting close.

When I run mine in the winter I always make sure to jet up it helps a lot in the long run especially with how MN winters get
