CNW Easy Pull Clutch Kit?

I also bought both the 3mm & 4mm plates from RGM, and have only tried the 3mm and found it instantly perfect! Simply couldn't ask for a better feeling clutch. The 4mm will remain in the box.

Have you tried a high torque throttle roll on like I described above?

I did test fit just a 3mm plate to see how lever pull was, it dropped from 24lbs to about 17lbs. The 4mm alone gave about 12lbs at lever (all measured with a luggage scale at the "ball" of the lever, pulling at near right angle).
I got too greedy with the 4mm plate ;-)
 
A friend of mine worked on his clutch and got it SO light. He was full of praise for it, super light, no slip, etc, the perfect clutch.

I had a go… it slipped like freakin’ Teflon when I gave it the beans !

Different horses for different courses (or riders) I guess !
 
Ok test ride completed following swap of "4mm" RGM plate with "3mm" (actual measures were 3.88mm and 2.88mm respectively). Stock plate being replaced was 2.0mm. So a net gain of only 0.88mm.
No clutch slip no matter how hard/fast throttle rolled on in 4th. Lever feel acceptable to me. Job's a good-un!

If true then there'd be no need for "easy pull" clutch kits and clutch pull can often be improved by 'tuning' (usually increasing) the stack height.



Unworn clutches can also benefit from the increased stack height as it is often 'low' even with new plates.

My Mk3's clutch pull was certainly lighter after fitting RGM's 3mm plain plate and that was shortly after fitting new (Surflex) friction plates.

with the 3mm plate, where is it fitting, replacement of a standard steel plate? or the front plate next to the spring? my Manuel gives the friction plate thickness as 3.759-3.607mm I have 3.2mm on all of mine. yet they sell these at 3.2mm or surflex 3.6 which are out of stock at the moment. RGM suggest a 3mm plate as you do.

so many conflicting suggestions. I am uk based

It makes no difference which steel plate you replace with the thicker one. I make it the last one inserted but if 3mm isn't enough, I'll try a 4mm and if 3mm is too much, I'll use a standard. So, if it goes in last it's easier to try another. There also is no formula - it all depends on the thickness of the other plates. The cNw fix is different. They provide and extra thinner than standard plate to make the stack thicker.

BTW, you can pretty much tell what's needed by putting all plates and the pressure plate in, pushing on the pressure plate, and looking at the distance from the outside of the pressure plate and inside of the circlip groove. If they there's a noticeable gap, you're not thick enough and if the pressure plate is partway into the circlip groove, you're too thick.

thanks, I will do that, no problems with my clutch it just got heavier then snapped cable by the lever. I don't get the fact they sell 3.2mm plates and the Manuel states they are undersize. onwards and upwards.

As marshg246 says you can replace any plain steel plate with the 3mm RGM* plate.

The 5-plate** clutch friction plates are (approx.) 3.2mm thick (plus 4x plain and 'thin' pressure plate).
The 4-plate clutch friction plates are (approx.) 3.6mm (3x plain and 'thick' pressure plate).
Edit:
*AN also sells the 3mm plain plate now.

thanks, I have placed all my plates in the basket and there is about 1.7mm to the end where the spring plate sits, so I assume I can put a 3mm steel and could replace one 3.2 with a 3.6 friction to get it flush, or should I just go with the 3mm steel, I have 3 with friction pads and 2 with a bronze plate stuck to each side of a steel plate that have oil ways in the bronze area.

as a matter of interest can you swap to a 4-plate clutch friction from the 5 plate. thanks again Neil

The 3mm plain plate could be enough. Yes, you can substitute a 3.6mm friction plate for 3.2mm, however, if the stack height is increased too far then you might end up with some clutch slip as the lighter clutch action is only achieved at the expense of a reduction in clamping force so it's possible to overdo the stack height.
