Inlet .0024 (two and a half thou.)
Exhaust .006" (six thou.)
(6) Set the valves:
Set the valves on the cylinder on the COMPRESSION stroke. Put the
wring
wrench on the locknut on top of the valve, and turn it anti-clockwise.
It will
be tight. Turn it about one quarter turn, and keep the wrench on it.
Then, using
the crescent wrench turn the square headed screw either in or out
depending
whether you need more or less clearance. We are talking about fractions
of a
turn here. Then lightly lock the locknut, holding the square headed
screw with
the crescent wrench so it doesn't move, and check the clearance. Repeat
until
it's exactly right. When it's exactly right, tighten the locknut.
Recheck.
(7) Rotate the engine one revolution exactly:
Shine the flashlight into either sparkplug hole and rotate the engine
slowly
so that the piston goes down once and comes back up. Stop when it's at
Top Dead
Centre.
(8) Now do the other cylinder:
Check the gap and set if necessary the other cylinder's valves
Repeat steps (5) and (6) for the other cylinder.
(9) Button it up:
Replace the valve adjustment covers, making sure to keep the gaskets
or
o-rings in place, the bike will have one or the other.
That's all there is to it!
