Absolutely do not oil those plates or anything to do with the clutch.
It is a DRY clutch and if you oil plates you are inviting them to slip.
This dry clutch just happens to live in the same neighborhood as the primary chain, which need a little lube.
And because it gets its lube from the oil in the primary, people wrongly assume the clutch is a "wet clutch".
I beg of you, do not oil or let oil get anywhere on your clutch hub or clutch plates.

ATF is fine, IF the primary is being filled with ATF, however, I, (and certain other Mk3 owners) would not recommend ATF to be used in the 850 Mk3 primary case as it does not seem to suit the hydraulic primary chain tensioner.

A "dry" clutch that will be wet with oil within a few minutes of the engine being started, so it hardly makes any difference.

You are overfilling the primary on a pre Mark3 if your clutch gets oily anytime soon after a fresh cleaning.
It is designed to function dry, and it is only unfortunate that a lubed chain happens to be close by.
Blessedly dry clutch and belt primary since 1998

My 750 plates always seem to have a bit of oil on them when I go in the primary, but it doesn't seem to bother anything, but I don't try to soak them either. It could be some of the grease flying off the bearing too, but it doesn't seem like grease.

But it doesn't really work dry, and I certainly don't overfill the chaincase and my Mk3's (bronze plate) clutch functions perfectly well under those conditions.
In order for the Mk3 hydraulic primary tensioner to work properly and refill quickly after start up a certain quantity of oil has to be constantly lifted by the lower run of the chain which then falls from the upper run as the chain passes over the hydraulic tensioner hopper, therefore it's unwise to run a Mk3 with less than the minimum quantity of oil.

I talked to Barrnett's tech people about new plates install and was told to wet good with ATF then wipe off excess and install to help initial bed in w/o chatter. Then run in oil or ATF or dry as you like. Type F might be a bit better on friction plates in primary while Dextron type might be a bit better in gearbox or forks.

This is starting to feel like one of our infamous "Engine oil" threads. I feel that I am over thinking this due to a coment from a conversation I can't even remember and should probobly forget any wat. I never worried about this as a kid, I just through it together so I could go ride. Lately I've spent to much time pondering things and not enough ridding!

Well you can always go with a modern road appliance for mindless riding but these ole Nortons often test a man's thinking hard enough to keep going properly. I fail too often at this to think I'm really up to it half the time. I've 3 different thickness pressure plates and hand full of used=extra steel and friction plates to mix and match till spring just barely slips in w/o any effort, but not more. Then I can measure stack to feel like a modern thinker. i can not detect any difference mix/matching types of plates in clutch fit and feel but mindless easy operation. Some pressure plates are Al.

Time to install the clutch and the parts that I have include 3 bronze clutch plates and one fibre plate. Okay, I'll go with that. But what order? I'm thinking the bronzes first closest to the gear box and the fibre plate closest to the last drive plate adjacent to the diaphragm spring.
Any thoughts on this?
