what is the valve gap for a 1999 Yamaha woverine
For the intake valve, the gap is 0.08 ± 0.02 mm. For the exhaust valve, the gap is 0.11 ± 0.02 mm.
OHV valve gap is 0.006" There is a YouTube video on the adjustment procedure and I will put the link below.
If it's an 8 valve engine and not the 16 valve: Bosch Spark plugs have a gap of 0.8mm NGK spark plugs need a gap of 0.9mm 16 Valve engines have a 0.9mm gap on each type of spark plug
The valve gap has to be checked when the rocker arm is on the "bottom" of the cam eccentric. This means that the cam has to be rotated as you check each valve, to get a correct reading. There can be variation in the valve gap due to uneven wear, but in a well maintained vehicle, this should be a very small variance.
The exhaust valve gets hotter than the intake valve.
