Question Quick Question... Are all Gen 1 eagle mike doohickey's the same??

Quick question for you guys. I'm a new gen 1 2005 KLR650 owner and need to do the doo. I have new eagle mike doohickey parts that are for a 1988 KLR 650. Are those parts be compatible with the 2005? I'm guessing they are the same but wanted to make sure before I start.

Thank you in advance for any help.

The answer is slightly complicated due to a lack of complete information.

First, Eagle has never made balancer lever parts that were specific to any year or generation of KLR. It's a one-size-fits-all thing.

Second, what you have depends on how long you have had it. Eagle has been making the balancer lever since the early-ish 2000s, if I recall correctly. It is only in relatively recent history that he came out with the torsion spring. He quickly found out that the torsion spring would not stay perched on top of the lever. It tended to slip off, which was Not Good®. To prevent that from happening, he machined a groove in the top of the lever.

Now, then, what is it that you have? Do you have the lever and two extension springs, do you have the lever with two extension springs and a torsion spring but your lever doesn't have a groove in it, or do you have the latest, a lever with a groove in it and the torsion spring?

For a long-term and satisfactory job, you want to have the latest configuration. That said, whatever you have will fit your 2005.

Thank you for the detailed reply! That was extremely helpful. It does not have the regular springs, just the torsion spring. That being said, I don't notice any notch on the doohickey for the torsion spring.

This is the best picture I can find, and you can kinda sorta see the groove in the top of the lever:


In this video you can see the groove at the beginning of the video and then you can see the handsome videographer snap the spring into that groove at 1:09:

He is so studly and masterful.

A triangular file will also make pretty short work of cutting that groove. As I have lengthened & deepened that groove when out of Dremel discs.

Usually drill the 1/16" hole at 5:00 behind the doo-hickey, unless otherwise instructed on the Torsion Spring package.

Although I like the torsion spring concept, is there a reason a regular coil spring that was shorter than the two provided by eagle mike was not a option? I replaced mine and I am pretty sure I still have good tension on the spring I have in there. If I tore it down to look, seems like it might be easier to just install a coil spring .250" shorter than the short one I installed. I have a feeling if I tore mine down I might leave it alone. I think it went in about 3k miles ago.

As you know the coil spring attaches to an arm on the same shaft as the doohickey, even when the doo is tightened down, the arm and coil spring can vibrate and this can cause spring failure. With the torsion spring installed once the doo is tightened there is no movement of the spring.

yep; the regular spring is a bit easier in that you don't need to drill the case but the torsion spring is far superior which is why Mike no longer ships them with the old style spring. The movement issue KLrian mentioned is one good reason to go with the torsion spring, the other is that the torsion spring is a "one time deal" and you no longer need to open her up to check spring tension every so often.
