Another question for all you helpful GPZ owners out there, (You
helped me through the carbs last time). I'am checking my valve
clearance, between the helpful chart, instuctions found on the GPZ
list and my service manual its going pretty good. I am a little
puzzeled though at one point. I am sure I found TDC for the two
position to check all valves. the problems lies with the #4 cylinder
exhaust valves and #2 intake valves, the positon of the cam lobes do
not look like there in the right positon and there is no clearance at
theses points. Every other point makes sense. Other than #2 intake
valves, all the rest are in tolerance. all the Exhaust valves are a
"little" tight (.05-.07mm) with the exception of #4 which is zero.
So I decided to check another way, and that is by putting the point
of the cam lobe 180 degrees away from the basket. I checked all this
way. All the measurements were the same except for the #2 intake (0
clearance before) now falls within tolerances like the rest, and the
# 4 exhaust vales are a "little" tight like the rest also. What
should I go by. Once I decide I will pull the needed shims.
This bike has 35k and I do not know the history of the so I'am
going through the bike.
