valve adjust is working :)

[timebombprod]

finally clicked and saw what i was supposed to be putting the ziptie in, shouldve focused more when reading instructions because its way eaiser than i thought. gonna put 2 vids showing where to locate the valve and also getting the shim off, im probably doing things i shouldnt but i guess its fine for the first time be more careful the second.

also i measured a shim that said 2.65 and my caliper said 2.50 or 2.51, and on another shim it said 2.52 do you think its because of a cheap digital caliper or something of my mistake. ill just double check them
update: ex4 2.52, ex3 2.50-.51, in1 2.53.

You might be applying too much pressure to caliper....but I too have found discrepancies with shim markings . Just keep the clearances on high side. Keep track of what shim you took out and what you put in for each spot. Steve?s spreadsheet might be calling!

 

[timebombprod]

update is in 1 :2.54, ex 4 :2.53 but had 2.52 the first time, ex 3: 2.50

i put the shim in place on the caliper first where it wont fall down sitting between the clamps and the turned on, took out shim, and closed gap. is that a good method?

1) Turn on calipers.
2) Press jaws together -- not forcefully, just press the measuring surfaces together.
3) Press the 'Zero' button, and make sure you've selected millimeters.
4) Use the roller thingy to open the jaws a bit wider than the thickness of the shim.
5) Put shim between jaws, roughly centered.
6) Use roller to close jaws onto the shim.
7) Read the thickness on the LCD.

okay in 1 is 2.53 ex 4 is 2.51 and ex 3 is 2.50 or .51 so can i narrow them down to 2.55, 2.50, and 2.50.


my clearance on ex 4 is .04 and the shim is 2.50 so should that be a 2.45 now, ex 3 was under .02 clearance and its a 2.50 so 2.45? and then in 1 is .04 and shim is a 2.55 so should it be a 2.50.

is .09 too loose? itd be ex 4 and in 1.

A couple of things I noticed in your first video. :-k

1. You spent a LOT of time looking through the spark plug hole, trying to watch the valve come down. Just turn the crank and watch the cam lobe push it down. After you get the zip-tie in, turn the crank one full turn, then pull the shim.

2. Don't use a razor knife to pry the shims up. It is far too easy to break the tip off, then you have loose metal flying somewhere. If you're lucky, it will fly into your eye. If you're not so lucky, it will fall into the engine and cause some damage.

3. Why the **** is the gas tank still on the bike?

Not sure I want to watch the second video.

second vid is taking shim out after i take tank off and it was on cuz i put away the valve project and did other things

do you think im measuring my shims correctly tho?

 

[Grimly]

Tip: to fish the shim off the bucket I was using a small screwdriver for years.
Then I discovered these...

You see the two at the front? They're excellent for getting shims out, and replacing them.
The stains might be old blood for all I know- that's a random library pic.

is there any object i can measure that is common in a household that could show me my caliper is accurate, like a quarter or something

You have me thinking. A standard sheet of notebook paper is .0035 of a inch. A nickel outside diameter is .836

 

[robertbarr]

Measure a few of your larger feeler gauges.

dang dude thats a really good idea thanks man i wish i thought of that

update: the caliper's inaccurate unless i am doing it wrong, for my shims ive got all the same reading consistently but the feeler gauges were on one time and off the rest.

 

[Rich82GS750TZ]

if you?re still doing it like this:

i put the shim in place on the caliper first where it wont fall down sitting between the clamps and the turned on, took out shim, and closed gap. is that a good method?

Instead if like this:

1) Turn on calipers.
2) Press jaws together -- not forcefully, just press the measuring surfaces together.
3) Press the 'Zero' button, and make sure you've selected millimeters.
4) Use the roller thingy to open the jaws a bit wider than the thickness of the shim.

6) Use roller to close jaws onto the shim.
7) Read the thickness on the LCD.

...then I think you?re doing it wrong. Turn on the caliper, ?zero? it, then do your measuring.

How about your feeler gauges?

Shims can wear down over time too which would measure less than they are marked.

Not sure you would be able to use calipers to measure that. :-k

Shims are hardened. More than the cams, so I would not expect much (if any) wear, and it would likely take a micrometer, not calipers, to measure any changes.

Also, unless you have previous accurate measurements on THAT shim for comparison, how can you be sure that the shim didn't start its life on the low side of production tolerances and wasn't really worn?

[tom203]

I just got some new 2.55 mm shims....they varied by about .0005 inch using my micrometer . I?ve found older shims that read about .001 inch below their markings. The cam lobes should wear more than shims, but they still show wear

I suppose there's a big difference between those quarter size GS shims and the smaller than dime size FZ1 shims. All my FZ1 shims measured at least .02 mm less than marked with my calipers.

 

[timebombprod]

measured my 2.45s that came in the mail today, confirms that my caliper is crap and is .15 lower than what it should read. gonna have abuddy check with another one to make sure but i think my new sizes i need are 2.60, 2.60 and 2.65.

Whereabouts did you purchase your shims from, I am looking for some smaller shims, very poor choice in the uk
