EVR Slipper Clutch Question

[Jruwducati]

I’ve had my EVR Slipper Clutch Installed for about a week now. Everything was working perfectly  and it still may be. The slipper is working well but today when I was riding it I noticed a slight grinding noise when shifting down into first. The pressure plate has the cylindrical bearings, there was nothing about greasing those in the install instructions. Just curious if you guys have had this issue. Bike is a monster s2r 1000.

I heard reports of a range of slipper clutches giving a clicking like feeling through the lever and that includes oem and aftermarket types. Is it a brief clicking through the lever or a grinding?

As far as lubing those rollers best email EVR. Did the fitting instructions mention lube?

I know the balls on the OEM slippers are supposed to be greased...at least that's what the Vet told me.

I need to adjust the stack height on mine, and lube them.

Maybe a smidge of HTB grease?

Stack height is a chore but a necessary one. Last slipper I had was in an NC30 which was a sprague type and I don't know much about the wet slipper in my Evo. I think I need one in my Gixxer.

I forget what he told me to use. It might have been a Moly type. I'll ask him before I do it.

Mine isn't slipping on acceleration, yet, but the engagement point is getting really far out inn the throw. A half mm should do it. I have an assortment of steel discs. I'll swap out my last 1.5 for a 2 and run it a season. Then I'll need to get 'creative'.

In the instructions for the EVR there is nothing stating to grease any part of it. As far as the stack height, Stephano over at Motowheels said not to mess with it at all to install it exactly how it came (following the instructions of course). Everything was torqued down to specs. He also mentioned that the EVR slipper is very touchy and if anything was installed incorrectly it would not slip. The thing is, it dips, rips, and most importantly it slips.

[ducpainter]

At some point your clutch might slip on hard acceleration. At that point something will need to be done to restore the stack height due to wear of the discs.

That's what I was referring to. EVR knows what the height needs to be. You might want to measure your stack for future reference, or if you can afford it, just buy a new pack every time it wears a little.

Good. So whats with the grinding feeling described? What did Stephano say?

[Jruwducati]

Well I was going to describe it as spinning a broken bearing very fast. When I talked to Stephano again today he said that A) it’s completely normal, the “mechanics of the clutch working. Or B) the bearing behind the clutch basket is broken. Now when I took the basket off to install the slipper clutch, I noticed that the bearing wasn’t broken, but the shield protecting the balls in the bearing was popped off. So, good chance it’s busted up now. Long story short, how do I remove this bearing? Stephano said it has no use and he removes them on all his bikes. Anyone have experience with out running that bearing?

[Jruwducati]

Actually, it appears that bearing doesn’t have shields on it to begin with? Looked at a few pictures and all of them look like mine does.

When i take mine apart, i clean the small cylinder type bearings and lube them. There seems to be conflicting info In the instructions and on the web about stack height and order of installation etc.
Just a note for anyone looking to buy. I made the mistake of originally ordering with sintered plates. They work well, but knock the sh#t out of the basket because they’re steel. I bought a new basket and organic plates, which are ally.

The only problem with organic plates in a slipper is that if you really use it a lot, like at the track, the life just isn't there.

Sintered ally discs are available...don't know how they work in an EVR setup.

Sorry, i should have said; it’s a 48 tooth version.
