If you need help with the R&R you should be able to do a search to get a thread that covers all the steps and hopefully photos. Or you should be able to find someone local with KLR knowledge. Or you can get someone to walk you through the steps.

For another option, Here is the program I have been using. It seems to be very good. Click on IJ software, download klr shimcalc to your computer, and you will always have it handy.

Shims are numbered...example...230, 235, 240, 245, 250, 255, 260, 265, 270, 275

The difference of every step is .002"

The larger the number the thicker the shim

You should be looking for a smaller number to create more clearance...example...an Exhaust valve measures .004" which is minimum clearance. The maximum clearance is .008". So you are looking for an additional .004" clearance. The shim is a 265 so you can use a thinner 255 (two steps) shim for the adjustment.

Default finally opened IJ's sheet

Thanks to all. I was finally able to open the one from Iron Jungle. (I'm kinda what I term "E-illiterate")

I will start my shim Job soon. I have 7-9 assorted shims, I have accumulated over the years. Hopefully I will have the adjustments covered.
I HATE going to my local dealer !! last time I vowed NEVER to return (40 miles/one way). I have been going to RonAyers since, but you really have to plan ahead.
This job you don't know what you will need till the rides apart.

Ride Safe !!

I understand the above, However when I use the spreadsheet i'm not quite understanding.

I have one Exhaust valve measured at .003 and has a 240 in there now, I want .010 or as close as possible. When I input the data it recomends a 233 but as I understand it shims only are in increments of 5 which = .002.

Based on the above I need a 225 to make a .009 clearence but the sheet shows that to give me .018.

What am I missing

Thanks in advance

You are correct....you should install a 225 shim to achieve .009 clearance on your exhaust valve.

Default Re: Valve Adjustment Shim Calculations - Free Spreadsheet!

supercat good to see that waterlooklr answered your question. I have never used the calcualtor but as you can see it apparently has the possibility of being incorrect.

Is your KLR an '08 or newer (Gen2) and was this the leftside exhaust valve? The reason i ask is seems to be a problem with the Gen2 engine. I have never seen a Gen1 KLR with that thin of a valve shim but I have seen and heard of many Gen2's with this adjustment.

Since this does not leave you much of a future in valave adjustments this would be something to talk to Kawasaki or the dealer about.

1997 and new to me 42k on the clock, first Valve Adj. It is the left Exhaust valve, tighter than a banjo string. It rides nice and has alot of power, thought tight valves might be part of the occasional backfires. It looks like maybe.

The left EXH was .003 with a 2.40 (more like .0025) right EXH was .007 with a 2.35 (Good There) Both intakes were .005 with 2.55 but I'm gonna go down one shim to bring them closer.

i would change the LE to a 2.25 for a .009", change the RE to a 2.30 for a .009 and change both intakes to a 2.50 for a .007 on each...more better...and shims are available from 2.00 to 3.00mm in .05mm steps...

Arrow Re: Valve Adjustment Shim Calculations - Free Spreadsheet!

I've owned six KL650s since 1991. I checked the valve clearances on my '99 at 18,600 miles/purchase
and had to shim to these sizes to obtain the correct clearance:

LE .010 225 shim RE .010 230 shim
LI .007 235 shim RI .007 240 shim

I had to order the 225 shim!! since I had never shimmed that low before. I've ridden the bike 8000 miles since then and will check them again in another 4000 miles.....I doubt they have/will move much.

My calculations agree, and I have ordered new shims from ********* motors as another member had posted. 2 days shipping is better than wasting time trying find and swap around the dealers in town.


Thank you all, as usual your all life savers

You could have ordered new shims from EagleMike. He always carries a full assortment. Plus he stocks many items that no one elde carries. Today he comfirmed he has a stocks the choke bracket that bolts to the handlebrs. Who else carries this?

I think its great someone did this and people are using it and appreciating it. However,...


I just dont get why (mostly americans) have such a fear of math. In fact, we are not dealing with high level math here. Its just simple arithmetic. If your valve lash is tight, then you loosen by installing a thinner shim. Thats it, nothing more. If you can add and subtract numbers (with or without a calculator) then you shouldnt need a spreadsheet. I would be willing to bet that many people will use such a spreadsheet incorrectly and they would be better off just grabbing a pencil and doing the "math" on paper. Maybe we should hire a company overseas to do this arithmetic for us?

Sorry for the rant, this is not meant to insult anyone in particular. Just wondering what the big deal is about spreadsheets for valve adjustment.

The spread sheet worked well for me.

I do have a question though. I was under the impression that adjusting ( tightening) to within spec, it would assist in the cold starting of the bike. My 06 started well in the cold as it was. After adjusting the valves within spec, it now is a cold hearted beast.

Totally agree.

I Do/Use/Teach that the numbers on the shims are just that "numbers" and are in "increments of five" (270, 265, 260, 255, 250...). Each increment is ".002 of an inch".

Example:
Exhaust valve range: .006" to .010".

EX L is measured at .006" with a 270 shim.
EX R is measured at .007" with a 265 shim.

EX L can be corrected .004" or two shims therefore you would use a 260 shim.
EX R can be corrected .002" or one shim therefore you would use a 260 shim.

EX L corrected should measure .010".
EX R corrected should measure .009".

Not all shims are what they say they are. You should manually rotate the engine at least two full cycles after each adjustment and measure for correctness.

Some people teach metric. I find that most people understand "inch" over "metric". Simple is as simple does.
