I bought a set of dimple plates for my 2026 Montesa 260 4RT

I expected to see smooth plates with dimples in it but to my surprise every dimple is surrounded by a tiny edge which lays above the surface of the plate.

It seems to me as if it has been forgotten to grind them flush.

I can feel them real good so I doubt if this will work.

I am affraid it will destroy the clutch in no time.

Anyone with experience can give me advise in this?

Shouldn't I grind this flush and smooth?

I definitely would file them off If I was going to use them , but they sound like they are cheap rubbish from how you described them. Perhaps a better brand of product may be worth the extra expense.

Thanks for your reply

I bought them from a well known Montesa specialist, not my dealer, so I expected to receive some decent quality but I'm affraid you're right.

What is a good brand?

I don't have any experience in this matter.

I think I can get them in a useable shape but it will take some time
