Adjusting valves - what part is this?

I adjusted my valves and was reassembling/reinstalling the cam chain tensioner. In the egg carton slot where the parts were I had the body, three bolts, spring and washer, and a steel rod with copper tips that was 1 3/4 inches long. It's not shown in the videos I watched or my Clymer manual. It fits inside the spring, but I'm concerned because I don't see it mentioned anywhere.

Is there a rod like this connected with the valve caps, or somewhere else?

What year and model of bike are you working on & did you purchase the bike brand new or second hand?

Is it a solid rod? Or is it a hollow pipe? Do you have the hollow oil pipe installed between the LH intake & exhaust camshaft bearings?

The KLR650 has never used a tensioner spring "guide pin". But some other Kawasaki models have. Maybe a previous owner thought it needed a guide pin, because he had seen them on other models?

Is that pin 'short enough' to install into a totally collapsed tensioner, with NO spring, but with gasket & cap fully installed? If so, it shouldn't hurt anything.
If it is too long, I wouldn't re-install it. (Or one could shorten it.)

Thanks for reply. Bike is a '17 I bought new. Hollow pipe is installed. The pin is short enough to fit in completely collapsed assembly with no spring.

I just found a reference in the Clymer manual to the rod: "For 2012 models, engage the spring with the rod." I guess my 2017 has a 2012 engine.

No. Your engine is a 2012 & newer.

So that is 'another' tiny detail of 'improvement' that really wasn't necessary for a model that was about to be dis-continued!

Thanks for sharing, so the rest of us aren't surprised when we work on a newer one!

Ya know, the service manual for my first big motorcycle, a 69 Yamaha DT-1B, had horrible grammar and was written half in Japanese, but at least it showed the bike "as constructed" and the service processes were correct.

Ah, the good old days! I just keep marking up my hardcopy KLR manual with pen and ink corrections.......
