Setting up the clutch for lighter pull, "old hand" so have read a lot of strands. Any thoughts ? Am running RGM belt drive. I've ordered new drive plates and a couple of 3mm plates to go with the original 2mm ones plus a thin rgm pressure plate. I.E lots of combinations. Cheers, Roy.
 
Just received my Atlas clutch rod actuator ramp in the mail . I'll pull the cover and fit it tomorrow . Yes D.D. is the way to go .
 
RGM offers both 3mm and 4mm steel plates. I had a horribly stiff pull on my Interstate, I swapped an OEM 2mm for a 3MM and
the pull is perfect. A 4mm would have fit and probably resulted in a one-finger pull, but may have resulted in slippage.
 
I wonder how many of us adhere to Reg Pridmore's advice to pull your clutch lever in very little when you shift and shift quickly when doing so. It does take the heaviness of the pull a bit out of the equation?
 
My 'rule of thumb' method is to set the pressure plate flat with the compressor tool, and throw it all together. Once the circlip is fitted the pressure plate should just rotate with very little free play.
It works for me, anyway.
 
I've already fitted the atlas ramp. It wasn't lifting the clutch fully enough. The original plates show a fair bit wear and tear ! Time to renew and at the same time obtain a lever action that I can use without carrying ralgex spray for fingers ! Working to get stack to slightly more than stock. Roy.
 
Ive been running the rgm 3mm plate inplace of one original plate. Gives a much better lever pull...think is was almost half the force needed over stock when I measured with a luggage scale.

Anyhow, after a few thousand miles Im now getting slippage when opening the throttle rapidly, mostly when in 4th gear. Plan is ro swap out original sintered bronze plates with some Barnett plates (currently on back order from Walridge's fall sale).

Likely because I bought the last set . Sorry .
Not installed yet . Original sintered bronze that I'm using work quite well though , with the CNW hub center .
 
Bronze plates seem to hold particles from wear, and need washing off periodically.
Barnett plates are a popular replacement

A pox on you T.O.!

My original plates now have nearly 29k Miles on them, so perhaps they are just done. I could put back the stock steel plate and carry on with the extra lever load...but a lot of my riding is in stop & go traffic and the strain on the hand is considerable compared to the RGM plate setup.

Stop and go traffic in Vancouver is likely the same as T.O. I have a small car at my disposal every time we fly there in summer to fish .
Maybe the plates are indeed worn after that much mileage . I have 2 of the thinner type plates from R.G.M. , but they sit unused , along with your Barnett pack .
The clutch in traffic got unbearable recently , until I got home and pressure tool sprayed Teflon into the Featherlight cable . Back to normal .
 
Right. Afternoon juggling with all combinations and have ended up with standard clutch ? Put the spring in the empty drum . From the outside of spring to base of drum, 34.44mm . New Barnet plates(5) 16.02 +4 2mm plates+ thin pressure plate (rgm) 6.1 = 30.12. Then spring and pressure plate,4.4mm = 30.56mm. Hoping for a little wiggle room !! Pssttt, goes can 5 !

Ps original stack lightly held in vice , 29.19. New one should end up 30.010? Waiting for parts. Should give the extra 1mm that folk recommend ? Off to evening prayers, pssttt, 6th.

New clutch fitted with atlas ramp. 5 plate Barnet set up with rgmnorton.co.uk pressure plate. No room left for any other plate. Tight fit. Now have mutch lighter clutch (at great cost) but worth it. It needs to be pulled in to 1in from the bar but so mutch easier. Thanks to all, Pssttt !

Just recently purchased the Atlas ramp and have the 5 Plate as well , but not installed as of yet . Keep in touch on this . Some folks have said the clutch actuator Atlas ramp does not lift enough to fully free the clutch itself . Hopefully it was just an adjustment issue .
 
Best of luck. New stack measured in at 29.943 or close to. 30mm in essence. Wouldn't have squeezed in a 3mm plate instead of 1 0f the 4 , 2mm plates. Needed the rgm pressure plate to suit the 5 disc set up. 🤞, Roy.
