I'm running Rotella-T 5W-50 in mine right now. It's pretty nice, I gotta say

Synthetic?

I corrected my original post- the Rotella-T I'm using is 5w-40, not 10w-40.

I haven't seen a Rotella 5w-50. As a matter of fact, the only 5w-50 I have seen is Castrol Syntek, which I use in my 4Runner, but that's getting hard to find....

Maybe it is the 5W-40...

I'ma go check...

Damn I'm stupid. I'm running 15W-40... dammit I'm dense sometimes. It is the Rotella-T, didn't see wether is was synthetic or not.

Basically - ignore everything I've said in this thread.

I run Mobil Delvac 15w40 (non synthetic); its a 'diesel'(heavy duty) oil that's cheaper than Rotella.  I have always run this, and I've always been happy with it.  Of course this doesn't really help anyone compare anything

My bike hates synthetic, I bought a synthetic blend with the hopes of burning a little less..my clutch slipped and I couldnt find neutral. After 20 miles I drained it out and went back to my cheap ass walmart oil...

Stock GS clutches are cork which are prone to slip with synthetic. Some aftermarket clutches are Kevlar and do not slip with synthetic. I ran a Barnett Kevlar clutch with synthetic without any problems.

I though the rotella was 15W40.
I run 10W40 accel - SE spec oil in mine. Good, but I dont think I noticed anything really.
Cool.

Would that make it feel alot stiffer? or would it feel the same in the lever?

Lever feel will not be any difference unless the clutch springs where changed. Even with heavier springs, the clutch lever was not that much heavier. But then my grip strength is different than yours.

I've probably got 35 miles or so on this stuff so far. No clutch slippage. A lot of other folks are using it in MCs, report no slippage. Additives matter a lot.

You say "a lot are using it in MC's"....but...what bikes are they specifically? Not all bikes come stock with a cork clutch. Many come standard with Kevlar clutches.

Did you just say that my clutch is made out of tree bark?  Because that's what I think you just said....

Whay would that come as a surprise? The GS's technology and design is from the 70's.

Because cork is easily shredded by ten finger power, much less 40 horse power. 

It is a cork based material. It may have a metal imbedded in it, like aluminum.

Use it right and you will see 50K+ out of the shitty cork too. BTW the GSXR 1100's in the late 80's used to ahve the diaphragm type actuating and cork instead of the push rods and springs. Terrible squared. POS. And they still held up just fine.
Cool.

On your original question: Much of the engine vibration comes from pistons rods and crankshaft and is transmitted through the plain bearings of rods and crankshaft. So you'd expect different lubricants (especially different viscosity) to affect the vibration behavior.
