KX500 shifter kart build

<< < (22/22)

Polar-Bus:
Some more testing and tuning. Actually fattened up the main jetting a bit to a 170 main, the prior #168 seemed a bit lean running higher rpm's, and the plug was a little too light brownish for my liking. It might have something to do with the addition of the free flowing K&N filter. I also fabricated an additional engine bracket at the front that bolts to the frame, seemed to lessen the vibes somewhat.
