Clutch Plates

[xstian81]

The clutch on my CRM keeps sticking on, if left for more than a couple of weeks. I want to replace the clutch plates, steels and springs in an effort to try and stop this.

I've seen this kit.

I had a quick look on FAQ's and it says all clutch assembly's are the same between models. This kit is for a MK2 and the same kit is listed for a mk1 as well. I have a MK3 and I just wanted to make sure this will fit before buying and stripping the bike.

Does anyone else have anymore ideas on the sticking clutch? It's always done this in the 5 years I have owned the bike. I read somewhere cheap plates can make the steels rust and stick together.

Should be fine but heavier springs mean harder to pull clutch lever.

That's a fair point, I hadn't really thought of that. Do you know of any better kits? I seen the spring sold separately, but not sure if they are heavy duty as well. I could just reuse the springs I have, the clutch doesn't slip, so I can't see it being a problem.

Has anyone tried this clutch kit, or heavy duty springs?

[knackeredMk1]

As far as I'm aware (having tested the springs). Mk2 are the lightest, Mk3 are slightly heavier and the Mk1 has the heaviest of those I have tested.

The clutch set should in theory work with your original springs unless they cause your current clutch to slip.

It only sticks when I first ride the bike. Once it has freed off, the clutch works fine, no slipping or notches. I think I'll buy the kit and see how much stiffer the springs are compared to my old set. I think I may have another set laying around somewhere as well. It maybe the case you won't notice when they are in.

What oil are you using in the gearbox?

Could be an older filling of oil contaminated plates as well as current? I don't imagine the oil that first gets into the plates is circulated much.

I'm putting Putoline GP10 in it at the moment. I've had the bike for over 6 years and it has always stuck on, and have used various light gear oils in it. Is this very common on CRM's. My brother has a MK1 and his sticks on occasionally as well.

Well I've ordered the kit and I'll report back. I might be a couple of months, by the time I've fitted it and had a chance to leave it, to see if it cures the problem.

Its a funny thing mechanical objest.

I have 4 CRMs, was 5, and although all the same in every way, all stripped, cleaned and reassembled, same oil in each, only 1 stuck if left more than a couple of days.

Its nothing to do with springs, a new set of plates and clutch basket sorts every problem.............

+1, I would have thought all the heavier duty springs would do is push the plates together, harder

I don't think anyone is suggesting that the sticking problem has anything to do with the springs, heavy or otherwise.....

[fallenmikethebike]

My error, I was reading between the lines and I assumed that the referral to the springs being heavier duty was a pointer to that being the cure, rather than the kit as a whole.
The basket being in serviceable order, should allow the clutch to work correctly with the kit. I would have some cheap oil and flush the gearbox with that prior to fitting the new kit though.

I rebuilt the engine a year ago, so gearbox is clean. The clutch basket, although not new was serviceable with a little bit of cleaning up. I've ordered the kit now. So I'll do a comparison between the heavy duty spring, the original springs and a spare set I have laying around, to see which gives the best lever feel.

Hopefully the new plates will stop the sticking. I have a Laverda that sticks as well, but that will free off with a bit of gentle rocking. This never works with the CRM and sometimes the only option to free it off, is to ride it.

a laverda, wow.
you should be use to having a bike in bit then if it was anything like my one.
I had a laverda 650 sport Kevlar and most of the time something wrong with it.
