List,
My 98 has 10Kmiles of which I put about 7. I did my last valve adjustment
at 5Kmiles, and my stock chain is on it s last legs. As I am planning on
some tours, I decided to do a 10K PM. I found a broken balancer chain
adjuster. I can't say how glad I am that I found this before some real harm
was done. There was some issues with the Unitrak and the rear shock.
This is a description of my 10Kmile PM.
The plan:
New chain and sprockets (to replace the stock set)
Lube the Unitrak (never been done)
Pull the magneto, both side covers, and valve cover for visual inspection
and valve check.
Found:
Unitrak main shaft (not the swingarm shaft) was corroded. A little
stubborn, but some coaxing freed it fairly quickly. The bearings in the
left side of three-holed suspension arm were all not quite pressed far
enough in to allow the seals to seat, and one seal was buggered from a poor
installation.
Valves were great. I couldn t measure any difference since the last check
except the left exhaust had closed up less than .001 .
Shock absorber spring was installed poorly causing the spring to rub on the
shock body.
Balancer chain adjuster was broken. The idler shaft lever , the plate the
adjuster screw tightens down on with the crescent shaped hole in it was
broken such that the thin part on the lower part was broken and completely
loose. The screw was barely holding the adjuster in place.
I also just noticed that even though I had mounted the license plate up
high; the top right under the plate light with the screws going into the
bracket through the lower plate wholes is MIA. Looks like the rear wheel
took the license plate, the bracket and the bottom cm or so of plastic of
the rear fender. I don t have any idea when this happened =].
Comments:
I live in a very dry climate, and now I understand the complaints of other
listers concerning the Unitrak corrosion issue. There is a small hole near
the bottom of each cavity in the frame that this shaft slides through.
There was plenty of water in these cavities. A lot of very waterproof
grease all over this shaft, and more frequent checks are in order. I am
glad I didn t let this go any further.
The broken balancer adjustment plate was very disturbing. I m betting the
previous owner over tightened the adjuster, breaking the plate, but who
knows. I am so very glad I found this in my garage, rather than having it
let go while cruising through Mexico, or anywhere for that matter. This
could have led to a catastrophic failure.
Oh well, FWIW, it just goes to show you that a little PM can be a very good
thing. I realize that this is just my klr, not necessarily representative
of anyone else s, but it might make one or two of you consider tearing in
just a little further during your next maintenance session.

broken balancer chain adjuster, other 10k maint
Hi - Maybe I should have said something sooner, but my 1998 KLR also had a
broken balancer chain adjuster. I didn't fix it myself, but about two months
ago i heard a clunking noise when I gave it gas, and so I took it to a friend
who said it sounded serious. He is a Harley mechanic but he fixed it after
waiting two weeks for the parts. -Jennifer

It's too bad you couldn't have hooked up with my friend Brad Young in Elko, he is a KLRist and knows all, I mean all, the roads around there for hundreds of miles, and would have helped you out, he can also ride like the wind and fix anything wrong with your bike in minutes.> east instead of west, then south on hwy 93

I read his story, back then wasn't it in two or three parts? Great adventure. Made for some great bathroom time while at the office. Do I have to change the bearings? Why not check 'em? It's not hard, just pull of the front wheel (or block up the bike, but pulling the front wheel is better) and see if they are smooth and tight.

broken balancer chain adjuster, other 10k maint

Steve: I can relate to that. As I have relayed, the balancer adjuster spring broke on my A13, causing the balancer timing AND the cam timing to jump. Luckily, no other damage was done, and a $3 spring and $50 worth of gaskets fixed it. It seems that this whole mechanism is a weak point with ALL KLRs, not just pre-96s. I'm confident I've figured out all the snafus and will take care to do the PM at regular intervals. In spite of this all, I still like the bike, and plan on keeping it. An observation about the list: My several posts and updates on my serious mechanical problem and any hints to help fix the problem were met with tepid response (maybe 3 or 4 responses). On the other hand, if I wanted to know if its OK to put in 2.6 qts/ltrs of oil instead of 2.5, or what brand of air to put in my tires, I would have started a 3 day discussion. I guess it's a list thing. Dave>List, > >My '98 has 10Kmiles of which I put about 7. I did my last valve adjustment >at 5Kmiles, and my stock chain is on it's last legs.
