KLX 650 Valve Check

I'm getting ready to check/adjust my valves on my 94 KLX 650. I just bought the bike. I haven't ever done this sort of valve adjustment. It looks hard reading the manual. Has anyone here done theirs and is it easier than it reads? Thanks. Steny

you can also do a google for Jay's famous KLR valve adjustment video. http://www.duchinproductions.com/videos.html (I'm assuming the KLX is very similar) I bought the DVD and it made the procedure as simple as pie! I was leery at first but was SO glad that I didn't pay my dealer $230 for what took me 2 - 3 hours. and it was fun to learn the inside of my bike too! It is empowering to "do-it-yourself".


Here's a KLX-specific page


I don't know if the KLX is shim-under or shim-over bucket. The KLR is over which means the camshafts can stay in. If the KLX is under, the camshafts will have to come out. The man to PM is Subterranean. My dad bought a killer KLX from him and the guy knows these motors well. Doing your shims is fairly easy once you've done it. Don't get discouraged! You'll save quite a bit of money doing it yourself rather than having a dealer do it.

I just looked at the fiche. It's shim-over, which is good. You do NOT have to take the cams out as shown on the page. A small screwdriver and magnet will get them out without removing the camshafts. Do your feeler gauge thing, do your math to figure what you need, and then roll the motor so the cam lobe is off the bucket. You can pop them out with little trouble. Have at it. :naughty:

Thanks Guys! Steny :naughty::naughty::D

I just checked mine for the first time last night, very easy\

The hardest part of the whole job was getting the valve cover off, and getting the two clamps broken free, the one ties together with the oil line, near the cam sprockets.

Then a small screwdriver, and tweesers, or a magnet, and the shims are out.

I had 0.00 clearance between the cam lobe and the spacer shim, and my bike was very hard to start wit hthe starter, but would fire when pop started imed.

I will report if this fixes the problem when my new valve shims arrive friday at the parts tore.

Sounds good. My KLX has a 13:1 piston (95 LR Stroker kitted bike), but is hard to lite up. I'm hopping the valves are the problem. Already have troubled shooted the coil, stator, CDI and spark plug lead. And cleaned the carb once. Just bought a second KLX 650 (94) and might switch thecarb from it to my 95 to see if that makes a difference. Going to Baja this weekend. :naughty: Will work on it again next week. Steny

I'm an ass. You DO have to remove the cam caps, but just barely lift up the cam high enough to pop the shim out and slip the new one in. Sorry for the earlier bad info. :naughty:

      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: http://www.carguy.org/klr650/shims.html 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!!

      I have about 25 years riding experience, have a budget of 10,000$ Canadian and need a bike that is street legal in Ontario Canada, but can handle some real off road and highway riding. I'm between 210-220lbs, 5'7" and want a new or nearly new bike with a comfortable stand over and I want something that already comes with some features and bling.
