Slippy, squealy, grabby Clutch in !st gear -1098 Slipper

Can someone tell me if this sounds like the fix for the above mentioned problem.

Adding 1-2 convex Discs in the Clutch assembly.

What happens only happens when I rev the bike above 3500 rpms  or higher and let the clutch out at once from a stop.

It fixed my non slipper. I added one in the opposite direction from the one in there. More than that might affect the operation.

You should use a scotch brite cookie on the other metal plates to clean any glazing.

I had a similar problem after the slipper install.  The first time I rode the bike it nearly got away from me because of the non-progressive action and I wasn't expecting it.  I *think* some of it is caused by losing the spring/shock absorber in the hub (plus a lot of weight).  I added a couple of the convex plates and a clutch stabilizer from TPO and it is much better.  I've also noticed the friction plates wear at a quicker rate now.

edit: I can get you the part # for the beveled plate if you need it.

if you are using a bearing type, they are normally quiet, except for 1 part of it.

The pressure plate no longer has teeth to engage the hub. Instead it has its own metal disc this is what causes the squealing sound when you first engage the clutch.

that spring, along with the convex plate, i always thought was there to help the plates free up when you pull in the clutch since they can stick to each other sometimes.

So Nate, you added one to what was already in there ?

You didn't replace one with a convex plate ?

Was it a 1098 clutch or do you think it matters that much between models ?

Thanks for your advice.

Hi Bill,
When you say beveled plate you are referring to the Disco Comboto ?

Which model bike did you do this to ?

Hi, The package says disco bombato driven disc.  p/n 067516530.  I replaced a couple of the flat plates.  They are a little thinner than the flat plates so you have to check the stack height.   I put them on an '07 S4Rs with a MPL slipper clutch.
