how do you know if you need to re jet the carb...will it not run,run hot....just wondering

 

If your machine bogs when you give it gas or you have black chit on the end of your pipe, that meens your too rich and you need to jet down.

If it pops when you give it gas "kinda like a backfire" "same sound" then you are too lean and need to jet up. good luck!!

 

An easy way is to check your plug. Black is rich, white is lean, brown is just right.

 

Basically if you do any performance mods or change the altitude.
