Rekluse clutch in a pre '96 clutch

The Rekluse RadiusX for the KLR650 comes with enough stuff to install it either in a '96 to '11˝ clutch or in an '11˝ to 2018 clutch.

They offer nothing, no clue, no ray of hope, no branch to cling to, for the 'pre '96 clutch.

This is what comes in the package:


Clockwise, from the top: nine TorqDrive fiber/friction discs, the EXP centrifugal dingus, one OEM pre '11˝ steel, eight Rekluse steels. In the center are basket clips that go into the slots to accommodate the TorqDrive fibers with a smaller tab and, presumably, to take care of any issues with indentations in the clutch basket. Not pictured are some tuning springs for the EXP to increase the lock-up RPM.

The Rekluse fibers and steels are really thin compared to OEM. With a '96 to '11˝ clutch, it will have 10 fibers and 9 steels (the EXP dingus counts as a fiber) so it's pretty dang robust.

The problem with fitting the Reckluse to the pre '96 clutch is that you can't replicate the OEM 7 fibers/6 steels stack height very well with the thin Rekluse discs. The stack will come out either too thick or too thin and by enough to give the clutch lever fits and make getting the right amount of clutch pre-load a problem.

What I had on hand to do a mix 'n match in an attempt to replicate the OEM stack height was a whole bunch of OEM steels and fibers from every clutch that has ever been on a KLR, from '84 to '18. Doesn't that sound impressive, like the Shed of Horrors is just chock full of good shit? Eh, there were only two different steels and one fiber, at least as far as dimensions go. Don't be impressed. I'm just a pack rat.

The OEM stack height on the 'pre '96 clutch is 1.294". I built a spreadsheet to work up recipes. I figured that if I could hit the stack height +/-.010" that would be good enough. What I wanted to avoid, though, was using OEM fibers. To use them I would have to trim a dozen tabs on each disc I used, a tedious chore at best and not easy to do accurately over and over. As well as not using OEM fibers, I wanted to maximize the number of fibers/steels in the clutch.

Here's where I am right now; I got the stack height and managed an 8 fiber/7 steel pack. This also shows a few of the more promising recipes but none with OEM fibers:


Sometime this week, instead of taking the '09 back to the stone age with '84 ignition and a hybrid Gen 1/KLR600 charging (or doing any sort of real work), I'll get this clutch in and see if it works.

It seems to work fine. Don't know as I like it much, but will give it a fair shake.

Well that cool beans, Tom.

So in 1996 Kawasaki added 1 friction drive plate & 1 steel driven plate in a deeper clutch basket as compared to the 1987-1995 models, correct?
That tall stack clutch (8 friction / 7 steel) was used from 1996 thru 2011.5.

At 2011.5+, Kawasaki converted back to the shorter stack clutch for unknow reasons, but not exactly the original (7 friction / 6 steel) shallow basket, correct?

So what was different between the 1987-1995 shallow basket / short stack clutch and the 2011.5+ shallow basket / short stack clutch that had discouraged Rekluse from fitting their Auto clutch on to the 1987-1995 engines?

I figure that they just ignore the pre-'96 bikes as obsolete, that's all. They simply didn't bother.

Of course, if they do beta testing of stuff, rather than just paper engineering, they'd have to find a couple of pre-'96 bikes that get ridden a fair amount to make sure the stack works right. That might put them off of bothering.

Following bread crumbs . . . a pre-'96 clutch resides in your Generation 2 KLR650, accommodating a kick starter.

If false: Silly me!

All true, but I think @dallas is interested in knowing how that clutch works, feels, and survives in a real Gen 2 application. There is no one better to answer that than GoMotor.

I guess I'm on the spot here.

I originally installed a Recluse clutch in 2011 KLR. When a balancer shaft bearing went out and blew up the 2011 engine, I moved the Recluse to a 2008 I bought used. In one or the other I had to add or remove some clutch plates. My original intent was to mount a left side hydraulic clutch master cylinder piped to the rear brake to replace the foot brake lever so I could operate the rear brake with my left hand (right foot doesn't work).

It turns out that I can operate brake lever the with my left index finger while pulling the clutch lever with with the other three fingers. I now have the Recluse clutch adjusted so that it is barely engaged when the lever is out at idle. I can just let go of the clutch lever and give it a little gas before releasing the left hand rear brake lever and It accelerates smoothly from a stop. It has worked fine as advertised in both my 2011 and 2008 KLRs.

Although it works very well I don't see why you would need one except for racing or some other special application.

Wasn't meaning to put you on the spot.

I figured that you'd be the best one to have firsthand experience with the Rekluse. It seems to have held up for many tens of thousands of miles of fairly rigorous off-road use.
