"How To" Adjust the valves on your 125cc Kikker Hardknock with Hi-Bird motor.
For the intake valve I used a .003 feeler gauge for the exhaust I used .004. You can set the valves at different clearance than I did to suit your taste and conditions, the video is just a reference on how to do it. Keep an eye out for more Tech Center Videos from California Hardknock!
I do take requests, so feel free to drop me a line and let me know what videos you would like to see.

And dont forget, you can pick up your very own Kikker Hardknock at http://www.californiahardknock.com

Enjoy!

  • The same for 200???? and seems real easy!

  • @freestyleskier132

    Yep, pretty much the same for the 200, only difference is you will need to remove the tank (2 Bolts) and the top motor mount (3 Bolts) for better access to the intake valve

    Valves for the 200 should be set at .005 Intake, .006 Exhaust, feel free to try a couple different clearances, but these should get you started

  • is it the same for a 200cc ? seems like it would
