Hi triple people
Put new fibre plates in my h1e and changed the oil 15/40 mineral oil....now slips above 4000rpm.... didn't do this before and I haven't altered anything else very smooth action plates were from the Don so are good and correct
Any ideas.reason for changing them they had stuck together

did you soak then in oil before fitting them

Yes mate I did..

what oil are you using

15/40mineral Granville hyperlube apparently crappier the better

never heard of it, I use silkolene light gear oil in mine and no slip, assuming all is adjusted correctly ?

As far as I'm aware all adjusted ok must be oil would it have ruined my plates I've only done 5miles

Is it a motorcycle oil designed for wet clutches or for cars with dry clutches?

You need to give time for the plates to bed in, go do 50 miles of stop-start town riding,
then change the oil.
Did you rough up the steel plates with some Emery cloth to remove any glaze?
Did you put in new springs? It's very important that you put new springs in with new plates.
Springs loose their strength as they get old.

My guess is you have used ordinary car oil. It contains slippy low friction additives which is not good foe wet clutches.

Thanks guys for all your advice I rekon I've used the wrong oil my mate has given me some motul mineral gear oil ... I'll try this and see what happens....should I put another set of plates in again ?

No need for new plates just yet. Try washing the plates in white spirit , let them dry then resoak in the gear oil.

By the way the clutch lever on my H1e requires quite a pull . If yours is easy to pull then I reckon your clutch springs might need replacing too.

Thanks mate ....do I put 500 clutch springs in or 750 ones....do they fit ?

I don't know about 750 springs but 500 springs work fine. I don't think you can buy standard springs - at least you couldn't a few years ago . Mine came described as "heavy duty" , which partly explains the strong pull required for the clutch lever , but my clutch definitely doesn't slip .

Ok matey thanks

don't fit 750 springs 32 mm 500 34 mm

You could try fitting one or two H2 steel plates. They are slightly thicker than H1 steels, and could help by packing it out a little more against the springs.

I've ordered some heavy duty ebc h1 springs thanks for all your advice peeps

I used heavy duty and thought that my left hand had gone useless.

I seriously thought that I would never be able to open a pickled onion jar again.
