Doohickey and other questions

I just bought an 06 KLR.

Couple of questions....

1. What is this doohickey I keep reading about? How would I be able to tell if the doohickey mod has been done? Can it be checked visually? Keep it simple please, I am also new to the Kawasaki brand. My experience lies in Honda SOHC's 69-76 years. This is the newest bike I have ever owned.....

2. What are the classifications for Gen 1 and Gen 2?

Thanks in advance for your patience

I'm Not as much help as I wished I was!
I thought Eagle Manufacturing (Eagle Mike) surely had a picture of a doo-hickey which even I could Access! My error! Here is his description.
Balancer System

Hopefully Tom S. or Damocles will supply a proper picture, soon.
Essentially it is the "Engine Balancer Chain ADJUSTMENT Lock Lever".
Totally separate system of the Camshaft Timing Chain!! Which has an 'automatic' adjuster.

The crankshaft rotates counter-clockwise. 3 separate weights rotate clockwise to help smooth out what you and I feel at the handlebars, seat and pegs.

Gen1, 1987-2007. Gen2, 2008 and up.

Modify at "YOUR OWN RISK"!

Still riding my 1987 KL650-A1. 85,000+ miles & counting

The KLR is fun and easy to work on, truly.

To begin, find a knowledgeable KLRista in your area and become friends! You'll learn a lot like that.

Secondly, ask around for a KLR tech day in your area. You'll learn so much about your KLR...and meet some cool people, as well.

Check/adjust your valves, see what mods/farkles you might want to try, adjust your suspension, talk about oil & tires, just bask in the glory of being in the exclusive KLR owner/rider club.

There are two rules for being successful in life.

Rule 1: Never tell others everything you know.

Thanks Dan,

Unfortunately there are not a whole lot of KLR's in my area and definitely not enough to have a tech day. Its a small town on the north shore of New Brunswick. Luckily I am getting to know the guys behind the wrenches at the local moto shop. Good guys and they know KLRs pretty well.

While I have some images of doohickeys, this exploded parts diagram might be more meaningful:

2007 Kawasaki KLR650 KL650A Parts, 2007 Kawasaki KLR650 KL650A OEM Parts -

Look for Reference 13168; LEVER, IDLER SHAFT.

The stock part is shown; usually a two-piece welded affair (Generation 1). An aftermarket doohickey will likely have better fit and finish; don't know if you can tell if yours has been "done" without digging into the engine, removing a couple of cases or so.

Sound maintenance to upgrade a Generation 1 doohickey, IMHO; however . . . given the age of your machine, Bayesian probability suggests your part is likely to survive, as-built.

If you do go into the machine in behalf of the doohickey, installing Eagle Mike's "torsion" tension spring appears to be a good idea to me; offers adequate balancer chain tightening torque much longer and with greater reliability than from the stock spring.

Damocles, Thanks very much for the input.

I have no problems digging into it to learn things, but I will admit, I am a bit intimidated by it, having no prior experience with these bikes. In the past I have usually had someone who "knows" peeking over my shoulder when it came to engine work.

That said, I appreciate the web version of peeking that has already been offered by many members on this forum.
