longevity off Dr Pulleys

Like most people I have fitted Dr Pulley sliders, but, I wondered how long before they should be changed? I don't mean all the technical buff about measuring, if normal pulleys have a life of roughly 20/30 thousand miles what ,roughly should we expect from the pulleys, any ideas?

I measured my original set of 28 gm Dr Pulley sliding weights with a digital caliper. They were in-use for 60, maybe 70 thousand, miles and had no measurable wear. FWIW I sprayed PB Blaster with Teflon on the weight ramp tracks.

Currently I've switched to 26 gm Sliders and Dr Pulley ramp plate Sliding Pieces.

Thankyou for early reply, I use the brake cleaner spray on the variator and metal parts but just use a cleaning cloth on slider parts. I wonder what the sliders are made of, probably a trade secret.

Old Limey, you could give the ramp tracks a coat of this to make them 'slippy' ....

what would the benefit of lubed ramps be? Wouldn't it lower the gearing for a given rpm, since the sliders would move further out under centrifugal force due to there being less resistance?

No it wouldn't alter the gearing, it would improve the smooth operation of the moving componants thus reducing wear & increasing their working life

FWIW I ran DRP sliders in my '03 Burgman 400 for over 45 k miles with no discernible wear, and see no reason why they would not last 100 k miles
