Wondering if anyone knows what size jet to put in my raptor for close to sea level???? i am live in seattle and ride the dunes pretty often but also ride it above sea level. I have a k&n filter and will be install the full system, what size jet are you running and what kind of riding do u do??
thanks

 

I would try about 155/160 with air box lid or 160/165 for no air box as a starting point.

I'm running the GYT-R slip-on on with K&N. My jetting is at 155/160 with the lid and no snorkel...runs great and I'm a little over sea level...
