I pulled the plug on my raptor today and it is black as ****. I knew that the bike was running rich, but have just been living with it. It seems to hesitate when you floor it, but runs fine after it clears. It has also been very cold natured during the winter. Here is the low down:

No airbox lid
K&N filter
E-Series slip-on with 12 discs
DJ Stage 2 Jet kit
146/148 Main jets
Needles on groove #4 from the top
Mixture screw 3 turns out
I live in south GA

Should I adjust the needles? or what?

Thanks Alot

 

add 4 discs to your muffler and drop the needles to 3rd clip position [img]i/expressions/face-icon-small-smile.gif[/img]

 

That sounds like a plan. I will give it a try. Thanks.

 

I can already tell that it made a difference without riding it! I haven't added the discs yet though b/c I can't find my longer bolts.

Thanks
