When fitting  the plug,  always clean  the

Wipe off  any  dirt from  the threads  and
screw  in  the spark  plug  to  the correct

Check the fuel lines  for leaks, crack, or  mal-
function. If a problem is  found, your Yamaha
dealer or other qualified mechanic should re-
pair it immediately.

are fitting a spark plug, a good estimate of the
correct torque is 1/4 to 1/2 a turn past finger-
tight. Have the spark plug adjusted to the cor-
rect torque as soon as possible with a torque-
wrench.
