The clutches are pretty durable. I would trying adding some Seafoam, or MMO to the crankcase, drive it for about 200 miles, drain, change the filter and refill. If it helped at all, repeat the process.
And the oil thing? I would try Shell Rotella T, or Chevron Delo 400, 15w40.
I hate myself here

, but I gotta back up what mikef is saying.
Before you do anything mechanical, stop, think, wait some more.
Pour in some Seafoam, a full 1/2 can at least into the engine oil. Ride it for a few hundred miles.
Personal experience. I bought a '94 with 60,000ish miles on it. 3 POs and maintenance? None from the evidence I could see. Almost nothing worked right on this bike.
But back to the clutch. It would slip in the higher RPM ranges at full throttle. I had to be power off in a shift, or varoom the engine would go, but not the bike.
I poured in a can of SeaFoam and ran it 200-300 miles. A couple of weeks of work/back. Changed the oil, and a lot of crud came out. So, I repeated that dosage, and ran it two more weeks, More crud came out, put in some Chevron Delo 400 15w40 (Phoenix heat ya know) and Oh My Garsh! No more clutch slipping.
That's my story and I'm sticking to it :action:
