There are a few options without doing a strip down, starting with an oil change using a flushing oil and a few frequent oil change [ I would g this road first unless its been a very frequent issue]. Up to and including drilling into the housing to get a cleaner into the sprag clutch- 88 on the forum here has done this successfully.
But if you have other reasons to go in then maybe consider doing everything else in there.
I had mine apart in February due to failed rear main seal and gearbox leaking oil all over the place.
So I did the lot, as in rear main seal, flywheel seal, gearbox seals, clutch plate and bolts, gear position indicator switch and gasket, release bearing, clutch pushrod boot clip etc. alternator monkey nuts [didn't replace, done 2 years ago and still good], possibly new clutch cable if old one is dodgy [do it anyway and keep old one as a spare], clutch pivot bearings and circlips, driveshaft boot and new clip, exhaust gaskets studs and nuts. Just been in and done all mine and got best price from Motobins. Because I was faced with postage costs I went and ordered the lot in one order and everything was here when doing the job. I did a few other jobs too- brake switches and fitted hazard warning switch, Motobins is a simple plug in and go.
If you do go in to the sprag clutch you would probably be mad not to do the lot or at least do the rear main seal as it will go and when it does clutch plate goes with it. I had 78,000 miles on and the clutch [original] had at most 5,000 miles left in it.
Over a few weeks I dosed everything and I mean everything in WD40, not one nut or bolt troubled when taking it apart. The bike lives outdoors under cover.
For now its oil tight. I have also done final drive bearing and brakes since too.
