jetting question

[CPLMULLINS]

im have a problem with my pipe cherring out on me while im riding could it be caused from not having the bike jetted right?
bike 08 yfz, current jet size 165.

What is "cherring"? Getting red? Is this at night?

[CPLMULLINS]

ya and its just more visable at night.

[Jeremy]

Its normal to be able to see that at night. If its super noticeable during the day you might have an issue.

im not tring to sound like an a**hole but i know that but the whole pipe from the head to the exhaust canister is getting red.

sounds like your to lean if it is getting that red and that far back. What mods do you have and what jets are you running?

[CPLMULLINS]

the only preformance mod i have on the bike is an aftermarket exhaust and right now it has a 165 jet in it.

With out knowing more, I am going to take an educated guess. Bump the main to a 168, change the needle to a NVCQ YZ dirt bike needle and set it to the 3rd clip. Maybe change the pilot from the 42 to a 45 and set the air/fuel mix to 1 3/4 turns out if your getting some decel popping.
