tool for measuring bore: what's it called?

Edited Date/Time 10/14/2014 5:21pm
I'm buying tools for my kx250 rebuild and need to check whether my cylinder bore is within spec. What's the proper name for that tool?

You need a micrometer to use that tool. You set the micrometer to the bore diameter in your service manual, then use the appropriate extension in the kit. Insert the dial bore gauge into the micrometer and turn the dial to zero. Whatever the dial reads after zero is the wear on the cylinder.

You need a REAL micrometer, not a set of digital calipers.

Like this, get a couple micrometers for 125 and 250's

Sorry ,that is not the way to set a bore gauge!
not even close!
I like how you clamped your mic in thr vise!

You need gauge blocks( certified) , special gauge block
clamp set-up, surface plate.

Oh stop it! Where in a KX250 service manual does it state to use "special certified gauge block"?

It's for a clapped-out 2000 kx250, not a lamborghini. My manual actually shows a technique very similar to what kidkawie has shown

Thats a perfectly acceptable way to set a bore gage for this type of use.

Setting a bore gauge with a known standard
versus a micrometer( when was the micrometer checked with
a gauge block) really determines the quality of work.
You could easily be off dimensionally as much as .002-.003 thousands

average vs excellent work.

In 30 plus years in a true machine shop, I have never
seen a machinist do that
In my shop you would be fired!

Rob, looks like you learned something then. Because that's how you setup a dial bore gauge. If you use your micrometers as c-clamps, thats another story.

Welcome to engine building.

"Perfect" is the enemy of "good enough" lol. I'm thinking in the case of me checking the sleeve of my 2000 kx250, that the micrometer method is fine. Nothing wrong with being thorough, though.

good enough for who? I like to get lots and lots of use from an engine rebuild. Totally up to the rebuilder though, maybe a super short life span from mismeasuring is good enough, and spending money on the proper tools seems silly

Well, using the technique that is similar to the one used in the manual, as opposed to spending hundreds of dollars on "specially calibrated" tools . I dare say if that kawasaki would specify exotic tools if they were needed. They don't. Again, the manual technique is very similar to the one kidkawie showed. Bore Guage and caliper. No specially calibrated plates, if the manual is to be believed. Kawasaki could be wrong I guess.

Update: the kawasaki manual does NOT show how to measure it lol. It was my Suzuki rm250 manual that shows that procedure. So, although it seems to be a valid technique, kawasaki only specifies the measurements- not how to get them. I think I may end up buying a new cylinder in the end. I just don't trust a sleeved cylinder.

You are all wrong, and you just do not get it.
None of you work in a real shop, yet you are
experts.
Now that is funny!
I have been building engines,machining, and
repair machine work since 1973.

LOL, you are fucking priceless man. How many awards have you given yourself? Maybe try explaining how to do it rather than just shitting on people?

Rob, if the micrometer is accurate what is the problem? What is YOUR method of measuring a 2 stroke cylinder?

If you Google "setting a dial bore gauge" all the results are what I described. Are they all wrong?

No, the fact is that you advocate specialized tools (at premium costs) to perform a job, when not even the factory manual calls for such. Ive never seen one post from you that wasnt either bragging or berating someone for "doing it wrong" You need to build yourself a special chamber for smelling your own farts, Rob.

Too bad for you! Giving people the wrong advice, stating that, is
not berating ,or bragging! Doing the job right once versus spending money twice or more
is foolish, let a qualified shop bore the cylinder.
If you do not want to spend money on tooling, Do not do the job
Factory manuals
are just general instructions.

If you believe Kawasaki sets there bore gauges that way at the factory
you are wrong!
They would laugh in your face!

Stating any of this is not bragging!
just the truth!
If you are offended you really need to call
a wammbulance!
And post your name!
and picture!
What are you hiding!

Go spew that shit over at practical machinist., they would have a ball with you.

Some "machinist" you are not having faith in a friggin micrometer. lol

Still waiting for your idea on how to measure the cylinder not using a micrometer, dial bore gauge and I highly doubt you would use a t bore gauge.

You are stupid!
And you just do not get it!
It just shows that you have never checked
a mic, or gaged one
Stupid in the dictionary has your picture!

No he is not. LOL, sad but true and an all too familiar story here.

yes, even Tbagged must admit its true, but do not be sad, you can all take your
