A stock, well prepped but otherwise stock RS will certainly be around 75-80hp if you are looking at an earlier Pro-Arm model (70-75 for a pre '92... if you can find one in "stock" condition!), and if looked after, i.e. scheduled rebuilds, could actually be cheaper to run than the NSR as the top-end is cheaper!!
Setup really isn't much different to the NSR. Unless you are striving for that last 1hp, running it a tiny bit rich and leaving it there won't hurt; just like most do with an NSR or any other 250/2-stroke to be honest. Sometimes you may pick up 1-2hp, sometimes you may loose 1-2hp, but with 75-80 on tap, and it all just being for fun, it really doesn't matter!
Smiles per miles though... priceless!
