doohickey story - long
Posted: Fri Aug 16, 2013 4:08 pm
by RobertWichert
OK, so I have never done the doohickey. Mea culpa, mea culpa, mea
maxima culpa.
But I am trying to atone for my sins.
So my bike started to vibrate more than I was used to and I started to
worry. I loosened up the doohickey holder bolt and I think it helped,
but not much. Then I started taking things apart.
I took out the cam chain tensioner and it was not at the limit of
extension so I felt good about that. I pulled it all the way in, and
then when I put the spring on, I heard it clickety clack out so I know
it is at least working.
I then decided to take off the side cover and take a look. I was a
little surprised to see so much oil in there, but what the hell. I
could barely see the doohickey but I loosened up the holder bolt and
tried to move the doohickey and it moved pretty easy, both ways. It
occurs to me that maybe the spring is broken, but I can't see it since I
haven't taken off the flywheel/rotor. I plan to do that but I may put
it back together before I do that since I don't have the wrench and bolt
yet.
So now for the questions...
Does the fact that the doohickey moves easy, both ways, indicate that
the spring is broken?
Should I move it by hand clockwise, like the spring would do?
Is it ridiculous to ride it like this?

Robert,
It sounds from your description that the doo tensioning spring is broken.
You could try to tension manually by moving clockwise (with some
pressure) and tightening the doo adjusting bolt. But how much is enough
and how much is too much???
To me it seems ridiculous to even consider starting the engine with a
known issue. Until you take it apart and discover exactly what is broken
and at least try to recover broken parts you have a potential time bomb.
Having it go off while parked would be bad. Having it go off while
riding it could be deadly. You might never find all the pieces but it
could cause issues if a broken spring end gets into a bearing or other
important part.
My suggestion is to order an EagleMike doo and torsion spring and only
use an EagleMike rotor puller. The rotor holder could be made or maybe
borrowed and the puller could be borrowed too, possibly.
You are almost 1/2 way to having the doo and spring replaced. Why
wouldn't you do it right now???
Best,

Yeah, OK, I thought so, Jeff.
I already ordered everything. I tried to get the "puller" (I think it's
really a pusher) from the dealer. They want $105 for it! Ripoff! They
had some "generics" in the store, but I just ordered it from Fred along
with the doo and a new spring. I'm not going with the torsion spring,
but I am considering having the spring shot peened. Here's why:

I'm pretty sad about not being able to ride the bike. It is my primary
transportation and I don't like having it offline.
Oh well.

Thanks Robert,
It does sound like your spring is broken. I wouldn t operate your engine until you have your counter balancer chain tensioned. If you are needing to run your bike before we get you the parts to fix this problem, you could try tensioning the lever with light to moderate finger pressure and tighten the bolt. This would be much better than running the engine while it was loose.
You should have your parts on Tuesday.

Thanks Fred,
I bought the "magneto holding tool" (wrench) from the local dealer. I'm
an idiot. Could you get the wrench out today if I order it from you?

I'm pretty sure I've been running it like this though. I noticed more
vibes than usual and I was wondering so I took it apart.
How strong is that spring, anyway? I kind of feel resistance, but it
may just be the chain.
Would a broken spring cause more vibes than usual?

Robert,
The spring puts a pretty good tension on the doohickey. When you get to
the chain there will be no more movement.
A broken spring by itself probably won't cause more vibration. What
usually happens is the spring is broken because that's what happens with
KLRs. Then instead of fixing this common issue early in the bike's life
the owner thinks it won't happen to them. The spring breaks and there is
absolutely no indication in most cases. In a few cases part of the
broken spring gets into an important part and destroys the lower end of
the engine. In rare cases it locks the engine and causes an accident.
Finally the owner decides they should do some maintenance and loosens the
adjuster lock bolt about a turn. Since there is no spring tension, any
tension that was on the chain is relieved. This is a slack chain and can
put the balancer shafts out of time just a tad. The owner tightens the
adjuster lock bolt to 69-71 inch pounds and thinks all is fine. What
they really did was loosen the chain and cause a problem. They may
notice more vibration but since they still feel lucky they attribute it
to the KLR being a large thumper or something else.
On the Gen I KLRs the springs are known to break more than the doohickeys
but there are problems with both. On the Gen II KLRs the springs often
are no longer providing tension by 1,500 miles and for sure you are lucky
if at 5,000 miles there is any tension at all with the stock spring. The
Gen II doohickeys are redesigned and much stronger than the previous
version but the hole is often a bit larger (0.005" or so) and doesn't fit
on the shaft quite as well as it should/could. The fix is the same in all
cases and cost is pretty reasonable compared to the cost of damage that
could be caused by not taking care of this issue.
Best,
Jeff Saline

Robert,
I had a broken spring at the 10K mile check up on my A14. (Hard to believe but on my '92 that I put over 30K miles on, I never checked that stuff.) But,on the A14 had only adjusted the tension at 1000 miles. Put a stronger spring in there and adjusted all before I put the mag back on to see how that stuff works. LOL! Now, I don't take a chance. I just pull the cover ever 10000 miles and adjust it with a screw driver shovin' the thing right to left since that's how the spring pulls it. With a light I can bearly see the spring is still there. I coat the gasket with just a smearing of silicone seal. This makes it easier to come apart without breaking the gasket, plus, helps seal. Then, I don't concern myself with it for another 10K miles and knock it out during an oil change.

Update...
The spring was, and is, definitely broken. The crankcase hook end is
MIA. The spring itself shows some signs of abuse (Dented a bit. Prolly
got caught by the chain or something.).
I will try to find the hook end.
I also need to look for one thrust washer which appears to have gotten
away from me. Fishing expedition starts tomorrow.
This is probably just for curiosity, but how do you index/time the
balancer(s)? Is there a mark or something? It appears that I can
remove the tensioning sprocket. As a matter of fact, the insides of the
tensioning sprocket fell out on their own. I haven't moved anything,
but I'd like to know that the timing of the balancer(s) is right, so if
there is a way to do that, and you know what it is, kindly help me out.
Any other hints or ideas are welcome.
Bottom line - Bad spring. No cookie.
