Jetting-'06 YZ450F

Many thanks to those of you that posted the 48/170 combination. Before starting my new bike I installed these and adjusted the low speed speed mixture to 2 turns and it was spot on.

How much better does it get :thumbsup:

One kick starting since the rejetting!

TT is a great place...send "Burned" a Christmas card!

I am grateful for learning about the rejetting here. :thumbsup:

i'm running a 165 mj a 48 pilot, stock leak jet and are the rest,

i have a ready air filter, and an aftermarket exhaust system.

My fuel screw is set at 2 turns out, in 70 degree weather.

i'm just wondering if i should move the clip up on the needle?

on the start line my bike was popping a bit, so would that help at all? or should i play with the fuel screw some more?

what about a bigger main jet like a 170 go smaller with the 160?

thanks

In 90 degree temps yesterday the 48/170 combo worked flawlessly all day with no popping :thumbsup:
