Who ever in Kawi designed the KLR head ..

Needs Bitch slapped !

i was checking timing on my 2001 KLR and adjusting valves and exhaust was way out of spec ..also noticed alot of bluing on cam lobes ..

once i pulled caps it was scored and outside cap was loose !

looks like it got hot when it got stolen ..

but too my amazement klr does not use any type of bearing in the caps for the cams at all ! in fact if its worn i am supposed to replace whole head !!

what fricken monkey makes you throw away whole head to replace a bearing ?? oh thats right there is no fricken bearing !!!

when the cam caps are worn there is no bearings to make it within spec ..the head and and caps are machined as one unit the part numbers are even the same ..

what a stupid throw away design .. just retarted .. i Have 2 heads now with same issue ... scored caps head side looks fine but cams and caps are hosed ..

KLR650 engines, generally speaking, enjoy profound service life. With adequate lubrication, lots of miles can be expected from the camshaft/cylinder head interface.

Machining camshaft journals in cylinder heads is not unique to Kawasaki KLR650 engines, I'm told. If replaceable camshaft bearings are an important, must-have feature, these properties can be found on other motorcycles of similar displacement, but at a much higher initial cost, I'd imagine, in comparison with the KLR's price point.

Bottom line, the camshaft bearing design decision, in service, has proven itself rather robust. Further, the manufacturing process appears efficient and cost-effective; wouldn't expect a change on future KLR650 models.

That said, I don't hold the KLR650 design perfect, by any means. Yet, I can live with a uniquely-fitted camshaft and cylinder head. YMMV!

-------------------

Oh, yes; a question from my own curiosity: What, exactly, is "bitch-slapping?" If a special technique of slapping (e.g., forehand, or backhand, etc.), could you please describe/define the process? Post a link or imbed a video? Or, if bitch-slapping is simply ordinary slapping, but slapping of bitches, please clarify.

Thanks!

Bitch-slapping is a gesture of disrespect toward the recipient of said slap: i.e. the "slappee" is not worthy of a real punch and is most likely not going to do anything in return because they are "weak."

Thanks for the input!

Extending the etymology further, is the practice called, "bitch-slapping," because "bitches" slap each other in that manner, since they are not strong enough to deliver a "real punch?"

That is, is "bitch-slapping" the way "bitches" slap?

I guess another possibility; a "bitch-slap" could be the type of slap appropriate for a "bitch."

Or, other? Which might be the correct origin of the term?

------------------------------

Never mind! I found at least FIVE definitions already from Google; more or less, one might say, "ALL THE ABOVE!"

http://www.urbandictionary.com/defin...erm=bitch-slap

I did notice, the Urban Dictionary says it's usually BACK-HANDED!

i have 2 cyl heads here that say otherwise, both with same failures on 2 different bikes . If the bike was designed to be rebuilt other than thrown away one could have spent 30 bucks on new bearings instead of $750 on a whole ned head just to get cam bearing caps !

having a cunsumeable part like bearing surfaces, i would expect them to be serviceable such a waste throw away a whole head just because of cheap kawi machining practices..

then it could really be ridden forever ..

its not just them trucks and cars are all going this way with non servicable ujoints and sealed bearings ..all because packing a bearing is too hard these days ..

How many miles are on the engines with the failures? Did you buy them both used? You did note that one had been stolen and possibly abused?

Sorry about your luck and I hear 'ya, but as you noted everything's getting to where it's non-serviceable and considered disposable. In the case of vehicles, good for the first owner who doesn't have the car long enough to need to mess with anything, bad for owners further down the road when these components fail and they have to replace an entire assembly instead of just a bearing.

We went through this a few years back when we had to pay over a grand to replace the front wheel bearing/hub assemblies on a Chevy Malibu. They came as one unit so instead of paying to have a $10 Timken bearing replaced, we had the replace the entire units.

Hope you're able to find a used head for a decent price and get back on the road, man.

both almost identicle miles 33k one is a 91 the other is a 2001 . Mine is the 2001 the spare parts bike is a 91 .

until it was stolen itwas taken good care of never a lick of trouble ..Infact i had far more issues with my 2012 with only 6 on the clock .

Folks in the "old country," had a saying: "A lot depends upon WHOSE ox gets gored."

If this misfortune had happened to ME, I might suggest punishment more cruel and unusual than "bitch-slapping" for the responsible designers and engineers!

But, it hasn't; giving me the detatchment of the uninvolved bystander/spectator. I modestly admit, I might not endure the tragedy gracefully, myself.

If I understand you correctly, wayne_l, you cannot account, 100 %, for the quality of maintenance during the service life of the two cylinder heads in question. No way to verify, OIL STARVATION was NOT the proximate cause in the cases of both camshaft/bearing/cylinder head failures. Maintenance often isn't a high priority with motorcycle thieves, it seems.

Thus, while sympathetic to your predicament and its attendant cost and inconvenience, don't know if I would visit corporal punishment (i.e., "bitch-slapping") indiscriminately upon the Kawasaki engineers, given their statistical maintenance record over more than 25 model years of KLR650 production.

Yet again; MY ox wasn't gored!

I have to agree with the OP...I had a Mazda 323 go the same way....my fault, I was young and I learned from this experience....BUT...it was the cam bearing, if you can call it that which gave way.....throw the head away and start fresh! Well a new head was worth more than I thought of the car so junk yard here I come....got one in very good condition....thanks to a stupid driver...lol. If they hadn't of driven off the road and smacked a tree I wouldn't have gotten such a good deal...lol. But for less than half of a new head I lucked out. Hope you do the same.....but this is a huge issue in our engines due to people NOT checking their oil levels. I would hazzard a guess that siad thieves knew how to do the never ending wheelie and thus no oil was picked up to get to the head.

I have just priced out a cam chain and a ballancer chain.....$110 and $241 and I want them both!!!! Just because IF either one does go for a turd the results are new engine. I have way too much tied up inside my engine not to put out!!! So, I'll buy the best arse lube I can find and go after Christmas and bend over!!! Damn I hate making stupid mistakes or acting without thinking of the consiquences!!! If I hadn't held the throttle open on the Dempster that time this past summer after trying to find an engine problem, this wouldn't be necessary!!! It has cost me $350 plus the gov't share.....augh!!!!...an expensive mistake I admit to....as I always do......
