Doohickey parts and tools, all years. WE ARE ONLY OFFERING THE TORSION SPRING, Choose options below
Doohickey 101 - In the '86-'07 KLR65's chain-driven balancer subsystem, two related parts are prone to failure: 1) the balancer idler lever (Kawasaki part no. 13168-1436); and, 2) the idler shaft spring (Kawasaki part no. 92144-1860). The two parts serve to maintain tension on the balancer chain. The OEM idler shaft lever is a welded piece. Because it is improperly supported, the lever can be easily crimped, dented, or warped. Eventually, the damage can become so severe the lever "hangs" on the crimped part and fails to allow adjustment to the chain tension. In some cases the weld fails or the collar breaks so the lever is no longer attached to the idler shaft and pieces fall into the oil sump below. Tension on the system is now held entirely by the idler shaft spring. Under tremendous stress, the spring can fail either by breakage or being stretched beyond limits. In any of the above scenarios, when tension is lost the chain is capable of jumping a sprocket, jamming and locking the engine. It is also possible for the broken pieces to find their way into the oil pump (assuming the protective screen is missing) and cause engine failure at speed. What about the 2008+ KLR650? The balancer idler shaft lever is improved but not nearly what it could be. But even more important, the factory extension spring is too long to do any good. It only gets worse with miles.
This Mike Cowlishaw (Eagle Mfg & Engineering) solution is made from 17-4PH stainless steel, heat treated to 44c on the Rockwell scale. The alloy is characterized by great strength, it is also tough and not brittle (corrosion resistance is a side benefit). The material is more than twice as strong as the factory part. The one-piece billet design dramatically improves the strength over the OEM part. The design also increases the bearing surface (along the shaft) by about 100 percent in length. It also is reindexed to allow adjustment for the entire useful life of the chain.
Included in the Doohickey upgrade kit is: one balancer idler lever and NO SPRINGS as of 1/29/18. We prefer to use the Eagle Torsion spring kit which includes a 1/16" drill bit for creating an anchor for the stationary pin of the torsion spring. The torsion spring offers significant advantages over a conventional extension spring setup:

We don't rent tools anymore. We could not get the tools back in a reasonable amount of time. We lowered the price of our wrench to compensate for the rental.
We don't provide the deep hole spacer as an option.
Early KLR's maybe up to 95 had a welded Doohickey and that caused stress failures, the design of the spring is also flawed and has a shrt life cycle.
First Doohickey Clinic we did in 2004 25 of 25 failed spec.
08 & later have a new design Doohickey that does not fail, the spring has the same issues with a short life cycle.
Eagle Mike Doohickey
Has a diferent timing position of the Doohickey Lever which allows for at least 100k of adjustment.
Torsion Spring has an infinite life cycle.
You need to do it now with your 2011.
The gaskets have to be perfect when we get them back so they can be resold to a customer. If you can do that there is no issue.
The tools are used and that is the expecatation the customer has when he recieves them.
