Hello there,

a few weeks back I became a proud owner of a KLR 250, since the bike had a questionable service history I gave her the typical treatment/checkup like changing all fluids, lubing up the bearings and adjusting the valves.

After I adjusted the valves she was really hard to kickstart the force needed to push the kick starter down was way too high, so I opened her back up again this time rechecking the valve clearance and taking a look at the KACR.

The Valves were ok the KACR on the other hand was very loose I was able to rattle on the weights and the rivets seemed more like guiding pins then connecting means.

Nonetheless I close her back up again and now she starts easy again(stuck KACR?) but I can now hear a rather loud ticking noise.
The ticking noise is seemingly coming from the KACR when I spin the motor without the valve cover on, I can see and hear the weighted KACR-“arm” jerk into position right as it touches the exhaust valve rocker causing a loud “click”.

Im quite concerned and have a few question I would like you guys to answer:

-Is this ticking noise normal?
-Is the KACR supposed to be this loose?
-Did my Valve adjustment cause this?
-I read some things about a “doohickey” causing loads of problem on the KLR650 models
does the KLR 250 have those too?

I’m sorry you had to read such a novel,
im no native speaker so im not that good in keeping it short.

Thanks in advance for every help!

I'll suggest, Normal.

Mechanical valve tappet clearances are 'best' when you can just hear them. I assume that you adjusted to 'just snug' on the thickest feeler gauge, but not beyond.

The KACR only operates at speeds Below about 800 RPM. So yes one will see a lot of movement of the KACR at kick-start speeds (200-400rpm). They are kind of crudely built.
With the engine running, turn the idle speed Down. One will usually hear a couple of 'klack, klack, klacks' just before the engine dies. That is the KACR re-activating.

One could set valve tappet clearances to minimum specs and do it twice as often, to keep the ticking of the valve train to a minimum.

There is not a "doo-hickey" in the KLR250 engine.
