What is adjustment for Yamaha gas golf cart valve?

Answer 1

Remove the valve cover, you will then see 2 rocker arms with a nut and a square shank. (older models have a 8mm nut newer ones a 10mm). you adjust one valve at a time, by turning the clutch until the valve you are NOT adjusting is at max lift. You loosen the nut on the valve you are adjusting. you now take your .010mm feeler gauge and insert it in between the rocker arm and the valve tip. spin the square head until there is a little drag when sliding the feeler gauge. next you put your wrench on the locking nut and hold the square head from turning (you can use pliers on the square head if you are careful) and tighten the locking nut. THIS STEP IS IMPORTANT!!!! AlWaYs check your work here, be sure the feeeler gauge is not too tight or too loose after your adjustment!! repeat this whole procedure on the other rocker arm. install valve cover and your done!!
