Help finding 29mm valve shims

I dont know why this is so hard, is there anywhere where i can buy a whole 29mm valve shim kit?!? Where do all the shops get them, why are they so hard to find?!

Ive got a klr600 ive veen working on, one exhaust valve is at .008mm and all the rest i cant even fit .004mm in there.. Might explain why i have no conpression, all four shims are 240 size, so im thinking i need like some 230s and 225s, maybe a 220..i managed to find one shim kit, for $126, but its smallest size was a 230, i would much rather pay a little more and get a whole kit then havr to sit and individually order them one by one and take weeks to get them set.. I also have an old yamaha im building that takes the same shims, its sizes are close to around 300, so a whole kit would prove very useful for setting everything

all the kits out there have too many large shims and very few small ones. and, they are too much money for what you get. go to somebody like Arrowhead in Moab or Rockey Mountain ATV and order what you need, and what you will need in the furure. the valves get tighter with more miles

What would be the cheapest place to get em? Im in salt lake so moab is a little far.. $7 seems a little much.. If i could get em for like $4-5 i figure i could get aeay with two 230's 4-225's and 2-220's

I agree with Beezerboy.  I used to build lots of KZ 900 and 1000.  I will check my stock and get back to you.  I have lots of 2.85 to 3.00.  Before I spend money and time on KL do a leak down test.  With test if you hear loud air noise in crankcase, light noise is normal, the compression issue may be deeper than valves.

  Any how I will get back to you on my shim stock.  

Oh yeah if you find that a 2.00 does not give clearance the valves are probably worn beyond service limits.


 Good day


Check your local Harley dealership. Harleys use the same 29mm shims and are usually cheaper from Harley.

Good to know, ya im gonna be picking up a little pancake compressor here in a few days, if im getting to much air past my rings then ill start looking into the 650 upgrade

What?! Good to know! I have a harley dealership just down the street! Theres one yamaha dealership out here that carries them but they charge $13 a shim, and the bmw dealership, well i think one requriement to work there is to be a pompous ass, if your not working on a bmw they wont talk to you period, and you say you have a BMW, even then they dont wanna help they say just bring it in..

the early  BMW "K" bikes used them too... and less money than from Kawi.... go figger


another intersting source is Ford. I got this info for the Tarus SHO engine.  29mm Ford shim thickness increments are .025mm .

Motorcraft E9DZ-6515- x......... the first "x" is the letter "N ".....   so E9DZ-6515-N is 2.300,  there is no "O" or "Q" in the code.  next letter is P... it  is a 2.325, R is 2.350, S is 2.375, T is 2.400.... out to Z which is 2.550. then it switches to AA which is 2.575, and continues as BA(2.60), CA(2.625), etc


this is old price data.... $3.04 $3.15
...SHO NUT Performance $3.55

Thanks Beezerboy

  That is some excellent info.  I would like to get titanium shim under set up for my KLR I just can not justify the cost.  Do you have any information about that setup?

I am not a car guy but if I remember that Tarus engine came from Japan (Yamaha?)?

      Hello guys,New to the forum.
      Quick question,I have a 1994 klx650c i recently purchased and am in the process of upgrading it.
      Have a trial tech vapor speedo ready to fit,however just wondering about the stock instrument gauges etc.
      Is it literally a case of unplugging the old dash and fitting the Vapor? Is the Dash used to complete the stock wiring circuit? e.g-if i unplug it and leave it unplugged is it going to effect the running of the bike? What about the dash lights,how would i go about wiring these up?
      electrics really isn't my strong point,got the basics covered but way too complicated for me.
      any help greatly appreciated,any more info you need please feel free to ask.

      Hello, This is my first post and I'm new to TT.  I recently acquired a 2008 KLR650 (which by the way I absolutely love) and I'm working on adjusting my valves, I already measured its clearances and found this helpful online calculator: however I'm unsure of what the shim factory setting size is and it is essential to get the right shims. Does anybody know what the factory settings are?
      Thank you!

      Recently we did a project bike with Dirt Bike Magazine's KLR650 and we were pretty excited about the results.  Check out the article on this fun project here:

      Hey guys,  
      A super duper THANKS for all the help, laughs, and fun I've had here, and the bike I put together based on advice and lots and lots of reading material you've provided on what is the best vehicle forum I've ever encountered (been on many over the years). . 
      Just when my bike was absolutely the bike I wanted it to be, my riding buddy (who is my father in law) bounced of his DRZ well up 4610 here in Oregon and broke his leg, and good. Tib/fib  job requiring rods, screws, plates, and a kitchen sink to put back together. If it wasn't for the MX boots I got him, and "forced" him to wear....there would have been all sorts of nastiness sticking out of the skin. No doubt about it, as both lower bones broke at sharp angles making spears inside his leg. As it was, everything was contained. He is going to be down for quite some time. I bought my drz to ride with him initially as he had a KLR650 and had an interest in backroad and moderate trail riding. On our first trip out (Brown's camp easy/mod trails) after about 10 times picking up his KLR with over-inflated 50/50 tires (mine stayed on 2 wheels all day long) he said "I need a bike like yours". Within a week he had his DRZ too! Then over the fall and winter we did all the mods and fixes to get them ready for this spring/summer.  It was kind of a miracle I even convinced my wife to let me get a dual sport bike. I'm 50 now, and have a degenerative vision disease called RP. Basically, I'm missing quite a bit of my vision field, but have decent vision straight ahead (unlike macular degeneration). I'm not in denial that good/full  vision is important for safe motorcycle riding on the street...and the reason I'm a 90/10 dirt/street guy. My argument was that we won't get hurt just poking around the woods, old man style, with occasional pavement work to connect trails (thus the need for dual sport over dirt bike).  Well, my father in law shot that theory down, but good!  He has dealt with so much pain over the last month, and met several dual sport riders in for riding injuries (some that make his look like a kid's day camp) that he decided he is out of the game. Unfortunately for me, that means I'm out of the game too. My wife is so worried I'm going to get injured badly, that it's not worth the fight. I don't want her and my daughter stressed and worried every time I go riding. My father in law was doing great on the roads and trails we've been riding. And just loved riding the DRZ. But he's 70 and looking at Jeep Wranglers with lift/tires for his forest adventures going forward. Not a bad call imo.  So...I've sold 2 DRZ's and a KLR in about 1 week (here in Portland OR, I could have sold 4 more DRZ's in the same time if I had them!).  His 1100 Honda shadow cruiser is on C.L. now as he is cleaning out the stable completely. Sad, sad day. It's only been a month since our last ride and I'm already missing the dirt big time. Even sold my daughters doodle bug. Oh well, life goes on. 
      Take care guys, ride safe (inside your skill level), gear up...and have some fun for me!!
