I bought a set of EBC clutch plates for the H2 - had to shave some material off the "fingers" of some of the plates as they fouled on the inside of the cases, and when I did manage to get them to fit it used to slip. Ended up fitting "barnet" plates and no further problems.
On the KH500 I fitted a set of EBC springs - you culd hardley pull the lever in, ended up fitting some NOS ones.
The EBC pads I tried in the front of the Him were no better, and if anything worse than the Indian ones - they also used to squeal - Brembo much better.
Perhaps I just have a thing about EBC products.
