Yes, Its a 10mm hex socket head, and if it hasn't been
undone in a bit, it may be so filthy you can't see it.
Its a ways down there, so what some of us have done is
cut off the "long" end of a 10mm allen wrench and square
it off on your grinder on both ends. Then you can chuck
one end into a socket, and the other into the bolt.

Got it.

Left side is finished. Wife wants breakfast, so moment
of truth in about
an hour and a half.

The manual says 6 head bolts, but I only find 5. 2 under
the rockers, 2
below the rockers, 1 under the spark plug. I checked
under that aluminum
cap at 12 o'clock, but there is no bolt under there.
Should there be?

Thanks,

-AJ

AJ, no need to torque the valve adjuster nut. Just
hold the tappet
screw
with a needle nose plier and tighten the valve adjuster
nut with an open
end
wrench. You only need to torque the head nuts. Catch
my drift? Bob

Have the right side done I think. Boy 0.15mm seems tight
to me. I don't
have a tappet wrench so I held them with a small pair of
vice grips
while I tightened the nut. Beyond me how you can use a
torque wrench and

keep the tappet screw from turning at the same time.

Off to do the left side.

Thanks to everyone so far,

Wow, that made a difference. THANKS! I measured
0.28mm intake and
0.30mm
 
 
 


exhaust. So that sounds like too loose rather than
too tight, on this
 
 
 side at least.

Just follow those tappet adjustment instructions
to tighten up?
 
 
 
Thanks,

AJ, Once you get the valves set prior to tightening,
make sure you hold
 the adjuster pin in the same exact position when you
tighten down the
 nut. They tend to move when you tighten, and it will
throw off your
 valve clearances. Recheck it to make sure, if it
changes loosten the nut
 

and try again. As I recall, re-tourque the heads
(BEFORE valves
 adjusted) to about 25-30 ft.lbs. Including the hex nut
below the cap on
 top (12 O'clock). You need to remove the rocker arms
to get to that one.
