Looking through the archives there seem to be a couple of comments about worn selectors and gears. Could this really cause the same symptoms as a slipping clutch - and if so, how?
Any other explanations as to what's causing it?

Next time you change the oil pull the clutch cover and the pressure plate. Pull the plates and chech them to make sure they are within the service limit.
You can also try this:
Preload the clutch springs with washers of the same thickness. This will slightly increase the pressure on the plates and it should cure a minor slip. It will also slightly increase clutch pull.

I had a look at the clutch not that long ago and it appeared OK (no visible signs of wear). Are there any tips on the best way to beef things up - springs, washers, better friction plates etc etc?

To pack out the springs with washers requires quite a bit of work because the washers must be the same ID and OD as the clutch springs - end up using a 1/4" washer with the centre filed out really large. But in the end this does not help much.
If you let it run for too long it will overhead the clutch basket & everything AND you are filling your oil with loads of friction material too!
JUST BUY A NEW CLUTCH KIT!!!! Cost £90 in UK, not a lot of money for decent reliable performance.

You should be able to get the steel plate from the wreckers.
BUT I would just go & buy new fiber plates & maybe springs aswell. Springs are extreamly cheap & you only need five of them.
Reliability is everything.

I have fitted a complete new clutch with H/D springs and boths sets of plates (Yam stock) hoping to rectify the problem, but it remains.
I thought the clutch I removed looked OK. It looks like it was an uprated clutch as it has dimples on the steel plates, unlike the new standard yamaha clutch I have now fitted.
Someone mentioned it could be oil type, ie going to mineral oil might solve it.
I am using semi-synthetic oil (which has been recommended to me generally as it is an old bike), against synthetic oil, as recommended by Yamaha in the workshop manual.
Or should I try going back to synthetic oil? Or none of the above?
if anyone can help I would be grateful.
All the best,
