It's simply a case of parallel development. It's a free country. I'm sure Elden and Mike put in just about the same amount of work as Jake and I (and all the other folks on the list who supplied parts and advice). They developed and produced a part, they have every right to sell it, at whatever price they choose. Devon A15 "wannabsmooth1 " wrote:

Hello fellow KLR owners, I have a 2006 KLR 650 that I have been riding since I bought it new, and I am ashamed to say that I am not very familiar with the internal anatomy of the bike and by no means am I a mechanic. All I have ever done on this bike is oil changes and I barely hit 4000 miles recently. However, I am extremely curious about doing this "Doohickey" upgrade since many people say that the stock components are prone to failure I would like to know some background. I have been reading a lot about doing the Doohickey upgrade to the "Eagle Mike" components, so before I purchase a set, I'd like to understand what it is exactly that I'm "fixing." I have been looking up the youtube videos on the repair, but I have failed to understand what the function of these parts are. I understand that they break over time, but it's been bugging me that I don't have a full knowledge of why and what I would be replacing.   In simple terms, what does the Balancer Idle Lever & Spring do? Also, what does to the balancer chain do? After all my research, I have basically only been able to understand that the Eagle Mfg. idle-shaft lever and spring replaces the weak stock unit.  Please give me a crash course on the questions and concerns I have asked. Simple engine terminology would be greatly appreciated as I said before that I am a total ignoramus when it comes to engine mechanics and functions (feel free to define components for me as I really love to learn about these things).  Thanks very much, Amin

It's not 100% smooth. But, it definitely helps. The "doohickey" is a small lever that tightens the counter-balancer shaft's drive chain slack whenever the adjustment bolt is slightly loosened. The spring on the lever pulls it and rotates an eccentric shaft holding an idler sprocket for the  chain - tightening up the chain and restoring the proper timing of the counter balancer parts. The adjustment bolt is tightened again to secure it in place. If the Doo breaks, the spring can come loose (along with the broken "doo" parts) and fall into the moving parts of the engine - possibly causing catastrophic damage. At the least, the broken parts fall down inside the case and the counter balancer assembly gets out of time with the rest of the reciprocating parts and the result is a bunch of vibration.     --- New Outlook Express and Windows Live Mail replacement - get it here: http://www.oeclassic.com/   -eddie Original Message:

As someone that has been around this list longer than the Doohickey has, I feel qualified to try to answer your questions.  First a little history about this part...  The first person to bring this part to the attention of the KLR public was Dave Jakeman who had issues with another KLR vendor who always embellished his parts with a lavish description.  So Dave used this simple description as a way to get back at this other vendor and also what Kawasaki calls it Balancer Idler Lever .  Confusing I know.   So the purpose of this part is to lock down the adjustment to your counter balancer chain inside your KLR engine.  Your engine would vibrate more without the counter balancer system and to drive these rotating counter weights Kawasaki chose to drive these weights by a chain.  Others have used gears to drive the counter weights and rightly so have made a pretty fool proof counter balancer system.  So the issue with using a drive chain is that this chain will eventually wear and the slack in the chain needs to be tightened.  Just like your main drive chain.  The way Kawasaki tightens this counter balancer chain is by turning a shaft that has an eccentric part to it that rotates a sprocket into the chain to take out the slack.  This shaft is rotated by a lever attached to a spring.  If the spring is broken then the adjustment can t happen.  If the Doohickey is broken the same thing happens.  This shaft is adjusted by loosening a bolt in the LH side of your engine which is in a slot in the Counter Balancer Adjuster Lever Doohickey .  The spring will take out the slack in the chain and then tightening the bolt in the slot of the Doohickey to keep that adjustment.  The Doohickey is plenty strong to do it s job unless someone is ham-fisted enough to break this part by tightening the adjuster bolt too much.  There is lots of speculation on which breaks first, the lever or the spring.  (kind of like the Chicken or the Egg)...  In either case the problem has been talked about way too much and is not as prevalent as you may think.  We used to do Tech Sessions in my shop where I would find about a 1/4 chance there might be any sort of problem.  From actual broken parts (rare) to the system not adjusting (more common).  The not adjusting problem is from tightening the adjust bolt so much that it rivets itself to the adjuster and doesn t let it release to do it s job.  Most time if you loosen the bolt and you don t hear the slack adjustment made by an audible snap , you either have one of three issues.  The adjuster is riveted to the bolt, the adjuster is broken, the spring is broken or there is no slack in your counter balancer chain to begin with.    With only 4000 miles on your KLR I doubt you are going to have any issues but the reason I have sold most of the Doohickey kits over the years is for Peace of Mind .  At some point it would be a good idea to check on yours but once you are inside to see what is going on you might as well replace these parts.  Like I said it s all about peace of mind.  If it doesn t bother you then leave it alone and if it does bother you then Do the Doo.

I had great luck buying a newer low mile stock oem shock and getting an aftermarket Eibach spring for my weight.  The shock cost me abut 90 total and the aftermarket spring cost me about $100.  5 yrs later still loving it.  I had to modify a cheap harbor freight mcpherson strut compressors to compress the springs to swap em.  I just grinded the claws or fingers of the strut compressors a little so they would fit in the smaller springs(than a car),

[nakedwaterskier]

Yes...the robust doohickey and esp. spring setup compensates(better) for the chain slack up to a certain point.  But, even the later torsion spring version cannot compensate properly for a very worn out chain.  But, these issues normally don't show up till at least 20k miles or until someone overtightens during adjustment.
