I had a few emails with questions on how to do this, so here is what I sent them.
Back all the adjustment nuts off on all rockers, then run them down with
your fingers until they touch (you will only be able to run down the rockers
with no tension on them... the ones with tension will have to wait their turn
on the next round when you rotate the engine 360 degrees. Zero the gage out
and adjust for ever how many mm or whatever measurement you want to use.
1. Put cyl #1 on TDC by using the TDC mark behind the crank case breather
on the front of the engine. You will have to remove the breather... I
believe it unscrews. You will see "TDC" stamped at 12 o'clock inside the
case and a mark on the fuel pump timing gear. Put that mark on the 12
o'clock TDC position.
2. Remove the valve cover, and mark the following INTAKE valves with a
paint marker, 1,2,4.
3. Now mark EXHAUST valves 1,3,5. with the paint marker. You should have 6
rockers marked now.
4. Adjust the INTAKE valves somewhere between . 15mm and . 38mm. , I shoot for
the middle of the road . 25mm.
5. Adjust the EXHAUST valves now between . 38mm and . 76mm. , again I shoot
for middle of the road about . 57mm.
6. Give all the rockers a good wiggle before removing the gage to make sure
all the play is out of them.
NOW ROLL THE ENGINE OVER 360 DEGREES AND ADJUST THE 6 ROCKERS NOT PAINTED
WITH A DOT.
Put it all back together, your done.
