fully closed position with the rod pushed all the way in (http://p1.bikepics.com/pics/2010%5C03%5C06%5Cbikepics-1920120-800.jpg)

fully open position with the rod all the way out (http://p1.bikepics.com/pics/2010%5C03%5C06%5Cbikepics-1920121-800.jpg)

 yeah they look ok
i assume the timing marks are line up exactly?   the flywheel side kips valve will look wrong on the closed position
this is due to 87 valves being identical but fitted to different sides

the recomended grease for the kips is molybdenum dilsulfide grease

I THINK YOUR PV TIMING IS OUT,JUST HAD A GANDER AT MY 86 AND WHEN THE ROD IS ALL THE WAY IN,YOU CANNOT SEE THE HOLE IN THE VALVE ON THE FLYWHEEL SIDE.WHEN THE ROD IS OUT YOU SHOULD BE ABLE TO SEE THROUGH THE VALVES INTO THE BARREL.HTH.

i wouldnt know how thats possible i have the notches on the valves lined up directly with the notches on the rod

if they are open when the rod is out I wouldnt worry too much, maybe the pics were at a different angle than i thought.

last time i put in valves i used copper grease spray [ not as thick as tub]  should be very easy to get
i put a small bit of standard grease on kips rod output seal
i cant see a problem using it     but any opinions welcome

 The guys that wrote the Kawasaki factory service manual do.

 They call for a molybdenum disulfide grease. Much better suited for the high temperatures in that area of the engine.

 i think the moly grease your looking  is used in cv joints of cars
 this i the copper grease spray i used [did not have a manual at the time] its got added graphite for even better lubrication    ,
we used to use copper grease  in excavator hydraulic  breakers,  now  they use moly grease  as a cheaper option
 anybody see any problems in using this,

you probably better using the recommended grease
if u do a google search on the moly grease it will give u loads of info on the grease and where to get,
i live i the UK so u probadly  have different brands to there in the US

i though the copper grease spray was a good option for me cos my 88 valves were pretty worn and thought they could be expose to a little more heat ,

not trying to be an a$$ or anything but why does it even matter any grease is gonna melt and run off eventually and the lube in the fuel should take over then

kawi calls for moly there b/c of its high heat resistance, +1500?F. My tube came from Honda  :roll: ask for it at the red dealer, u can recognize moly by its very distinct odor.
My personal opinion would be to do it right the first time with factory specified lubricants, but as mentioned, after running awhile the exhaust spooge of burnt 2stroke oil lubes some. They told you to just use BR grease, b/c thats what they had available to sell you. 4oz tube of moly might cost as much as two, 1lb tubs of the blue stuff.  I guess bottom line.....the wrong grease is better than none at all :mrgreen:

on that note, I just remembered lightly coating pv parts with H1R, the last time I did a parking lot top end and only had track box with very limited chemicals :-D

the copper grease i used is not going to melt until +2000"f ,
dont think the lube in fuel is going to lube powervales, gears ,bushes [ except for slightly around exhaust sub ports]
 i would not use any grease less than molygrease quality [ie any gease with a melting point below 1500f]
 melting boiling grease is probabaly going to do more harm than good

melting point? :lol:
what do u call it when grease overheats and turn to liquid?
Title: Re: 87 kx 500

 :lol:I knew what you meant! Just razzing. Technically, melting point is when things turn from solid to liquid. Not sure if you can apply that to an amorfious substance like grease, toothpaste, or ketchup( catsup). Thermal breakdown, or viscus change maybe? Again, I knew what you meant, just having fun :roll:
