I'm guessing the copper tube on the side is where the idle screw has been hidden behind a wax/gel. I'm still tuning mine in, upgrading lights and a couple other quick things, and want to idle a fair amount of gas through it before riding; this is where the idle screw comes in.
It's set just a little too low for me to walk away and let nature run it's course.

death wobble
 

Hey . :hi::hi:

I got the death wobble fixed. The tie rod ends were blown out after less than 30 hours. Cheap Chinese parts. I replaced both inner and outer ends, and all four tires with Sun f tires. I am very impressed with the Sun f tires, they are holding up great.
I am hitting 51 mph with throttle left, I am going to "play" with the powerjet, and the air/fuel mix. I was told that I could not hit 55, so I made a wager that I could. He lost the first bet when he doubted I could hit 50, silly rabbit..
Will post again. :D

Anybody here upgraded the carb and used the factory box ?
