Default Clutch Update

I recently hurt my left wrist and was looking at a Rekluse auto clutch. I have to update my clutch assembly to the 98-06 version. I have a 97 RK I'd like to square away first.

What else is required to update other than the clutch assy?

I'm sure many people have thought about this conversion for their Evo. Unfortunately, Rekluse only makes the clutch plates for Twin Cams. Not enough demand for Evolution conversions. I would be interested to know what needs to be done. I believe the TC clutch assembly will mount to a Evo tranny mainshaft. You would have to worry about compensator/clutch assembly alignment. Don't think TC clutch will work with Evo starter...just not sure. Let us know if you figure it all out.

BTW, I did call Rekluse and they were friendly, but didn't help much. They said some folks have done the conversion, but they don't know the specifics.

The 98 Evo RK has the updated clutch. I have no idea how much better the new clutch is vs the older one. I figured someone would have done the update. Hoping it is just a drop in solution. I'll have to sit down with the Parts Manuals and cross reference all the interfacing parts.

I have another bike I can ride until I get it figured out so I have the time, just no long rides until I'm sorted out.

Have you looked at EFM Clutches? They claim to be able to make any clutch an auto clutch. http://efmautoclutch.com/

Spoke with EFM.....can use my hardware to convert. The older steel holds up better than the newer aluminum so it sounds ideal. I'll be reading up on the EFM.

I'll also be doing some due diligence research on the EFM line of auto-clutch products for my 1985 FXRS. I'm closing in on 70 yrs old with arthritis in my hands that can make it painful to pull the clutch handle. No too bad at the present...but I'm pretty sure it ain't gonna get better going forward.
Thanks for the link.

I have no experience, but it exists and maybe will work for you, a centrifugal clutch:

The 98 up style clutch swaps right in, I grabbed a low miles take off from Fallen Cycles out of Daytona beach. If you've got some miles on her it'd be worth swapping a new primary chain, I swapped everything over from the late model bike, except the adjuster. Didn't realize my compensator was shot, til I had one that worked.

I used a piece of pvc pipe coupling and some 3/8ths thick steel plate to compress the old spring to get the old clutch off as the clutch tool is a single use only and you don't need it for the late model clutch. The threads on the bolt you need are goofy, had to go to fastenal to get one.

The updated easy pull ramps out of the easy clutch kit drop right into the release cover as well, they are stock on the late model bikes.

The late model clutch makes a big difference. The Late model clutch and updated ramps, make a huge difference together. I found that finding neutral with the old ramps, and the new clutch was a pain... she drops right into neutral with the late model ramps, hot or cold.

The 2008 up clutch perch and brake master cylinder work with the 96 up switch pods. They changed the geometry of both, and you get an easier squeeze by 10% or so than compared to the earlier parts... Brembo design. I flushed the master cylinder and kept the system dot 5. No problems.

Cool thing is that even with the late model ramps it still throws the clutch far enough that you can shift with a pinky and ring finger under the clutch lever, which was always the pain in the *** part of the old one. The old clutch took four fingers, so slick grass and gravel lacked control if you needed to turn it full lock and get rolling.

There are also narrow diameter grips that they put on the 2006 Sportster 883r, that get a few more knuckles on both the brake lever and the clutch lever. I was getting tendonitis in both thumbs, and that pretty much got everything squared away. They are only an 1/4 smaller diameter. I think the street glide low's have them if you want to sit on a bike that has them... but the right side grip off the 2006 883r is a carburetor cable throttle tube, new stuff has the electronic throttle sensor so the part number doesn't cross for the right side. It took a few days for them to order them in.
