I just brought home a new to me 2002 LC4 Adventure. The PO had broken the speedo pickup cable. I'm going to be getting a new one, but the way he had it mounted it was held on by only one screw and it was mounted way above the rotor bolts. I can't seem to find a photo of how the pickup is supposed to be mounted, anyone have a pic handy?

Thanks

Plastics!!

Does anyone have a good source for plastics for a 2002 640?

Duh, I see it now. Had read in a few threads that the speedo pickup was reading the bolt heads but there's actually a magnet set in the rotor.

Different stuff for different years, presumably. Rotor magnet in my 2003 EXC, bolt heads for 2005 LC4 Adventure.

Go back to the index on page one. There is link to Magura hydraulic clutch threads and that links to a couple of more threads where they discuss different oils. Plus I found some other threads using a Google site search.

I was just reading through them last night because I broke my clutch perch and have to do something. I love hydraulic clutches but just haven't talked myself into dropping $227 on one instead of $40 for a used perch plus a new cable.

So I was reading through everything I could find trying get off the fence about the Magura Jack/Hymec conversion.

Am I misunderstanding something? I don't see how using a different oil in a hydraulic clutch system will change the pull? my understanding is that the idea behind hydraulics is that the oil doesn't compress, regardless of type of oil used. if there is give in the pull, then there is gas/air in the line compressing, not the oil. To change the pull it seems you'd need to change to lighter clutch springs or change the geometry of the lever actuating the clutch in/on the case. i sure could be wrong, it wouldn't be the first time this morning!

I have already gone through those threads. But no one mentioned whether the lighter oil gave a lighter pull or not. Just that it got more smooth and/or more crisp, if I remember right.

Mine is smooth enough, but I would like a lighter pull. I think I would get that by switching to a smaller diameter master. But I guess, that would affect the distance, the lever should be pulled between the engage/disengage. That might not be an issue, since the distance as it is now, is not that long.
A Quick calculation says, that the 9,5 mm master give about 18% less output (can't express it much better. Help wanted) than the current 10,5 mm. That should equal to 18%
increased lever travel. But all this is just speculation.
I guess there is a reason KTM installed a 10,5 and not a 9,5 on the LC4, and i'm not very willing to just buy a 9,5 and see, since it's kind of expensive... Also I might be more willing, if i rode allot more technical...

It's kind of a mystery to me, why there's so much difference in clutch pull between different bikes. Even between same models (450's, 520's LC4's), not sure if they are same year though... Hope someone somewhere knows something...

Might be not all clutch springs are created equal. I've heard mixing oils can cause seals to swell causing drag but I think mine requires mineral oil, at least the 950 does.

A ragged edge on the clutch basket ears from the plates would also put friction on them as they move from the grove.

Did you consider an auto clutch?

A longer lever and move the perch in?

I saw a lever lengthened by cutting it near the ball, drilling and dowelling it back together with stiff wire leaving a gap to be filled with JB Weld.

I think I will just man up with mine - I could do with getting fitter (overall) anyhow!

I hear you, Not saying you, but so meany people I know blame the bike when they can barely hold on just riding a simple trail and need to stop for a break every couple miles.

I know on my 640 I drop from a 17 to a 14 when I get to dual sports then switch back when I leave. It takes away half of the required clutch abuse and makes life much more fun on the trail. If the place is less than 2 hours away, I leave with the 14 and make sure I leave early and stick to back roads

If I ever see a Rekluse or such come up for sale, I may buy one. I rode a 250 with one and it was pretty nice.

Or just go ride a bike with a cable clutch for a while then then LC4 one will feel heaps lighter

It may be worth having a feel of another LC4 clutch sometime just to make sure yours isn't unduly stiff though.

Cheers

Have you had a look at these? I love the feel of mine. I can't say that the pull is 50% lighter but on my new to me SXC the stock lever felt much heaver. So I pulled the Midwest Engineering lever off the SMC and it is much nicer.

Or install a Rekluse. My 625SXC came with one and it is amazing!

How long did you let it go before digging into it? Was the starter clutch failure caused by the bearing frag, or was that just a coincidence?
