I fitted a set of Norbo's race plates last year, as I had the cover off to change the o ring seal that was leaking coolant, couldn't stop it dragging, so put the old ones back in, ill revisit the issue when mine are worn out. you as well a?
I didn't measure the plates at all points though so cant comment on the accuracy of manufacture but when I next have the plates out I will and probably have a set of EBC plates ready to drop in.

You can take the extra thickness off by using a sheet of glass and wet and dry. Go slow and measure regularly remember to do both sides. Then re soak the clutch plates and rebuild. If it was me though I would try to take 1mm off the spacer between the basket and the centre.

Not a problem tobyjugs, this forum is all about discussing matters, that’s how we educate ourselves, However, the point i am trying to make is simply that a manufacturer will design the clutch to work within certain spec, so if the stack height is more than the designed stack height , for example by adding extra plates then each plate will in theory not separate sufficiently due to the basket not being able to move far enough out when the lever is pulled in, unless if maybe a longer pushrod could be used to give that extra adjustment, conversely as the plates wear adjustment will be made by the cable adjuster as you rightly say. I make this point because those plates i bought that were not a consistent size created me this very problem, I assembled the clutch with them and still had drag, i could see the problem straight away, the plates were still not fully separating when the lever was fully pulled back to the bar,so bit the bullet and bought the ebc plates which were all a standard 3mm thick and straight away problem of clutch drag was solved . When i measured the cheap heavy duty frictions that i bought with the vernier gauge , the total measurement was about 22.5mm in places, and standard spec is only 21mm for 7 frictions , it was that extra 1.5mm that to me was causing the problem. Hope you can see my point of view. Cheers. Exactly and also the springs will only compress so far which will limit the clearance .....

just an update , installed old steel plates , used silkolene light gear oil , just been around the block , clutch drag has gone
