I usually do drop a hint to the other squirrels who feel like General Discussion is for every topic.  You seem to have enough posts to have been around here long enough to know what’s going on … no?        

MH needs to get his head out of his ass and rename a few forums around here.  General Discussion is for general BIKE discussion and should be named so.

Can you imagine what a cluster fuck this board would be if there was only one forum for every topic under the sun?        

Do whatever ya want to do, but if everyone is too damn lazy or stupid to chose the right forum then this place will just be one huge cluster fuck board.

Yeah, juice.  But, just to be sure, put on solid surface and push down on center - where push rod seats - with the push rod and you should be able to depress the center some.  

Also, try to put back together with same lifter/lifters on same cam lobe they came from.  Same with pushrods.

After reassembly, fire it up, let it warm up.  Back off one rocker at a time until you can hear it click - tighten until clicking stops - go 1/4 turn (90 degrees) more and thats it for that valve.  Now do the other 15.

it'd be real easy to adjust them engine off right now since i have it all apart... except the motor would be cold...

i dont have a spare set of valve covers either

and when im setting them...
loosen the allen bolt in the center,
then adjust the outer nut until zero lash,
then turn the outer nut down another 1/4 tighter
then tighten down the allen bolt on top of that?

why do you think almost all of the valves would be that loose if they were hydraulics? since hydraulics should be under zero lash... just that far out of adjustment or set that way intentionally?

Cam could be going flat - look at bottom of lifters - should be flat, not cupped.

Some people think you can wind one a little tighter if you set up with no preload. (just remove click)  Won't wind any tighter and can, over time, start to click.

Seller could let them click and say it had a solid lifter cam (not likely, but possible)

Yes, you have the adjustment sequence down pat.

I haven't read all this thread, but I’m assuming you have a service manual that describes how to adjust they hydraulic lifters?

Once the zero lash point is achieved, the rocker arm is then turned another X turns to basically put the adjustment into the center of the lifter's inner piston movement range.

Looks like the X value you're using is 1/4 turn in from zero lash ... but are you sure that's correct.  I helped a friend adjust hydraulic lifter once, and it seemed a lot more than 1/4 in from zero lash was required.

Start it with #1 cyl. on compression stroke adjust it like this and they all get 1/4 turn and you don't need the engine running.

Start with the intake side------
With #s 1,8,4,3,6,5,7,2 INTAKE/EXHAUST fully open adjust #6,5,7,2,1,8,4,3 INTAKE/EXHAUST  Do it in that order.  Say if number 1 is open adjust 6 if 8 is open adjust 5 and so on.  

If your doing the intake just do intake and exhaust do exhaust.

Spin the pushrod with your fingers untill you just fill a little resistance from the rocker arm  pushing on the push rod. NOT TILL YOU CANT TURN IT ANYMORE.

fmart is correct, but i just feel better hearing the tapping. if you dont tighten the allen screws while adjusting, make sure you hold the nut while tightening them. as i said before if i remember correctly the nut is 5/8" use a spark plug soccet and a wrench on it and you can get a good grip on it while you tighten the allen screw.

ok, i just did that on one intake valve... felt tight at first, but i guess like you said above it has some squish room.... it felt stiff at first but after it set a few seconds i could turn the poshrod again without much effort... so that's the way i should do the rest?

I think doing it with the engine off is a good starting point but not knowing the condition of the lobes or lifters I'd suggest throwing a little oil around(covers off) and resetting them engine running.

the cams are pushing the lifters up almost .375 each

i got another question... a few of the lifters squish really easily and others are VERY stiff... is thatj ust because some have no oil in them right now and others are full?

Go ahead and adjust them like i told you to and you will be set.  Thats way I told you to tightent them until you fill slight restance.  This allows you to set the same preload on each lifter.  If that doesn't help after you start it up I have another way but they way I told you is the simpliest.

You did take and pull #1 plug to make sure it was on the compression stroke right? after you put the timing mark on zero.  Because you can have it on the exhaust stroke also.
