At the end of the rocker shaft, over the valve there is a slot head screw inside a jam nut. Just loosen the jam nut, turn the screw down gently against the proper size feeler guage placed between the valve stem and the screw and tighten the jam nut without letting the screw move back out of adjustment. There should be rocker arm access cap on either side of the valve cover that you can take off to get at the valve adjusters.

      I Crashed My Quad
      Well the Way I Ride, some of you knew it was Inevitable.
      Below are Three Videos.
      First one is Slow Motion of How it Happens.
      Second one is Normal Speed, and what happens after the Accident.
      Third one Follows more of what happens after .

      I Was Riding By Myself. I was going through a Mud HOLE Either there was a log or a rock, or A Dip but just as I was almost through it, Machine, Rolled over on my right side, as soon as I contacted the ground, I Heard A SNAP! I got up, flipped the Quad back over. I had the wind knocked out of me.

      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      First post here need some help/advice. I bought a 2001 king quad 300, vin number JSAAK43A212111871. I have been trying to do some basic maintenance as it runs but doesn't idle all that well . I want to take out and clean/repair the  carb but when looking for parts it ask for model X Y K1 K2. How do I know which model I have? I have tried some vin decoders but they haven't told me. If anyone could recommend a carb rebuild kit for my quad Id appreciate it. Also any tips on tracking down an owners manual?
