I did a search and it seems it's been awhile since the topic of the Hydraulic clutch has been talked about. Just curious after some time how people who are using the hydraulic clutch system on the K5 still like it, don't like it, problems with it, etc. Did 90 miles of single track last weekend and wore a blister and still have a pain at the end of my middle finger. Wanted to revisit this topic.

I have went through two complete systems and now going back to a cable. I'll start by saying a teammate with a cr500 has had his for years with no issues whatsoever. On mine, i melted the plastic line in about the first ten minutes. Then went to the braided line. Also had to make a bushing to take up some slack from the slave cylinder. The space between the cable holder and the clutch arm, must vary or something. I have had trouble with them leaking with every squeeze of the lever at the bottom slave cylinder, then recently used teflon tape on the threads, but it now pumps up pressure, to the point I can't squeeze it. I also had trouble with it completely disengaging the transmission. I could put in gear alright, but once rolling, I could pull the clutch in and keep going. A little nerve racking when getting ready to race it.
I have one for sale. :-D

HC42, thank you for the feedback. It's that kind of honest information that helps me and everyone make a good informed decision when laying down hard cash. I don't mind spending money on items that work and are reliable.

If Your cable is good and lubed right and you have a new lever with bushing or ballbearing pluss a new lever pivot bolt( that part is very important), You will be surprised how easy your lever will pull. If you use a lever with bushing don't forget a little dab of high pressure greese on the pivot bolt.

I really like his setup, & this is from the KTMs which are flawless. You can also lengthen your arm on the motor but it takes away some of the "feel".

Had a magura and went back to cable, for supermoto I lost "feel" of where my clutch was and on a supermoto on corner entrance that didn't feel right. I also broke the nipple that goes into the arm but magura stood behind it and sent me a brand new one that never got put back on.
Lookin to buy one? :evil:
-
i bought a magura and rode it in desert and really liked it. no problems.
-
There is one or two left on clearance at bikebandit.com for $259
Busted my middle finger all up and now it is a bitch to pull the clutch after an hour or so.
Even worse in this cold weather.
Id like to know the best one to get myself ....

I bought a magura and it sucked leaks every where
There is a mod here some where that makes the cluth arm longer much better (I use it)
-
never had a problem with mine, i've had it for a few years now and love it. i do always carry a cable for back up, but have never needed it...yet :-D i've found that the pull isn't that much easier than the cable, but it stays consistent. it doesn't stiffen on ya after a long ride.

Received the Magura Jack a couple days ago... bought it new. I am disappointed. The bushing on the slave unit is completely different than a stock cable bushing. In order for the bushing to be flush against the brackets, I would have had to grind a flat spot on the bottom of the bushing. Also, the slave actuator rod didn't line up with the clutch lever on the engine. Fortunately, I was able to return it for a refund. Anyone try an ASV perch and lever?
-
Anyone ever tried to mod one of these to a k5? I wonder it it's too weak because it's made for a pitbike.

I've had a Magura on my K5 for the last 4 years. NO problems

I use the ASV clutch perch and lever on my KX500AF. I use a CRF450R Honda brake master cylinder and ASV lever. The brake hose comes out of the back side of the Honda master cylinder and clears the Cycra hand guards. I bought the shorty version for clearance on the hand guards. They work great and I'm happy with them.

Here are some pics of the poor fit of the Magura setup for $239.00. You can see the 1/4 inch gap between the Magura bushing and the case brackets. Then look at the difference between the stock cable bushing and the Magura bushing. I could have made it work, but I would have had to grind down the Magura bushing. However, the actuator on the slave did not line up well with the clutch arm. I decided to send it back. IMO, it should bolt on easily for that much money.
-
Great pic! So what to people do to make that work. Looks like an adapter is needed to get it on the engine lever

No, there is an adapter-deal that they send with it. Same as my pic. I did have to make a bushing that I had to put a flat side on for clearance, so it was basically more like the end of the stock cable. I had no trouble really getting the slave cylinder mounted. It just leaked a little with every squeeze.
-
I ordered the Jack kit for a 2002 KX500. The kit includes some hardware to hook the actuator to the clutch arm. From what I've read most guys just modify as needed to make everything work. I found complaints about leaks here and on thumpertalk. Seems like a lot of guys end up going back to a cable setup. For 200+ Magura should include a bushing / slave setup thats bike specific.

Thanks Danger, thats a cool setup. I'm having some clearance issues too, with cycra probends. Does the pull feel any better with the ASV setup?
-
Have been using one for 5yrs. had to make spacer & bolt,just take your time with the install. kits never fit, we ride "500,s" not mainstreem 4 strokes,were a little differnt. no money in making parts for the few of use left.
-
It does feels better because of the bearing but the amount it takes to pull is about same. It pivots away from the handle bar in the event of a crash and the ability to adjust the lever to your hand/comfort zone that I like.
No big name companies are making after market parts for the K5. The day of 20 year runs without much change, on the manufacture of dirt bikes is over. They are a different bike every year. That makes it hard for the after marker industry to tool up. I don't think Magura ever made a KX500 specific hyd. clutch set up.

Guys,
Here's my issue, I bought the magura conversion for my 2001 kx500 installed it and bleed it 3 times, start the bike up and the clutch doesn't want to disengage. Okay no big deal since it's a used bike and I've rode it before this conversion with the oil coming out pretty sparkely I figured the clutches were probably worn. I tore the case apart replaced the clutch pack and covered it back up and topped her off and fired it up. Once I cranked it and pulled the clutch in the bike would do the normal jerk, good sign, let the clutch out slowly waiting for it to grab and it barely grabs at all. I called magura and let them know the issues and their response is it is probably not a large enough reservoir and that I need the 10.5, however looking at all their specs it recommends the one that I have installed. Kinda lost on the next step to get this beast back in the dirt other than switching back to the trusty cable and realize I just burnt my wallet of 250$$
-
I don't have an answer for you maybe one of the guys using a hydraulic clutch can chime in.
I hate dropping the coin for something that doesn't work.

According to the magura 2017 catalogue the KX500 from 1990 until 2003 uses
the HYMEC system 2100004 - the 0412310 attachment nipple and three spacer washers
0451530 are also required for fitment to this model.
I just would like to know the kit model you bought guys
thanks

Ive been using the magura jack on both my kx500 and to me, its way better than the cable it came with.
