In a bid to improve gear selection especially neutral I think I will be replacing the clutch in my falco - which has an rsv engine in it. I have a couple of spare clutches and just wondered if I should prepare one prior to fitting and if so what should I do. I have read on here about roughing up the steels slightly with emery paper or wet and dry and soaking the friction plates in oil. I think that perhaps the new engine had been sat for some time with no oil in it and therefore the clutch may have gummed up and stuck together? I could just clean that one I guess but probably easier and quicker to swap over the plates.

If you have a spare set of plates you know are ok then use those. just remember the last friction to go in is offset by 25 degrees ( sits in shallow tab recess ).
Neutral problem could be other things, clutch slave/master or oil jet

The roughing of the steels etc was on AF1 and was kzmille?
The idea he had was to allow the use of fully synthetic in the silver framed falco's.
This is a good idea but not essential as semi synthetic oil is cheaper and you will get the same miles out of the motor as running the rotax on fully synthetic.
I would remove the plates and check them against your spare one to check for wear.

This has been a long established practice both on AF1 and on here .... and on the old archived Ridersite.
It wasn't a method to get old bikes to run with fully synth but when they had problems with semi synth.

From what I've seen written, many people have found this to be very effective (never needed it myself as I've a later bike that doesn't have the dodgy clutch that some of the old bikes had).
On the other side of the coin I know that Griff is strongly against suggestions of roughing up the steels.

i just put the right oil in....

(I really disagree with roughening up the steels as well - no disrespect to kzmille but.... )

He' talking shit

oh i have no doubt it works

but

why?

semi is cheaper than full synth

for just about all of us - with the exception possibly of beef - we cannot tell what oil we use....

err yes .... but this was something that people did when they were running semi-synth (and we all know you can only manage a semi) and suffered slipping clutches - possibly after they had tried 10-40 too.
