I am experiencing clutch slippage while accelerating hard in the lower gears. I seem to have enough freeplay on the cablea and it only seems to happen after the bike is warmed up. Yes, thtey are the original plates and springs.

Thats exactly what mine is doing. I guess I am going to put in a new clutch. I am running 15/50 synthetic MA rated. take offs and normall acceleration fine. Nail it you get some slipage.
I asked in miscellaneous if you Have to use the tools prescribed in the book noone has answered

What kind of oil is a good question since friction modifiers are not compatible with a wet clutch.

Sounds like all you need is the Barnett Clutch Springs. Mine has not slipped since I put them in, but I keep trying.... Really. I think that's all you need, and if you can change your own oil, you should be able to change the clutch springs yourself, too. It's not that hard, and there is plenty of information here from earlier posts (that's how I learned), so I won't try to re-think the procedure here. Has anybody really ever burned up a clutch? Through normal wear and tear?

I agree with Keith (Blackwind) that springs are likely all you need. The EBC springs from FastEddy are great... and cheap!

VERY important info there, Ian. 
Last year I switched from dino to synthetic and I made sure I used Mobil 1 V-Twin just for this reason. And, even though it usually costs a little more than regular Mobil 1 car oils, it's definitely worth the few extra bucks to make sure your clutch resists slipping.
I wonder if some folks who are experiencing clutch slippage much earlier in the mileage of their bikes than one would expect are maybe using Mobil 1 or some other brand of synthetic car oil instead?
(btw...I currently have a total of 33K miles on my BA, with maybe 4K of that with the synthetic running in it, and so far with nary a sign of any clutch slippage to be found)
Yep! Just like a good Single Malt Scotch, you might call me "an acquired taste" TOO.(among the many OTHER things you may care to call me, of course)
