That's a great find, but don't expect too much out of it. The factory bikes were always a few HP up on the RSs, but there's no magic.... an NF5 is an NF5! 80hp only came with the later 72 degree motors.

An [un]educated guess would give an SPL kitted NF5 maybe a couple hp more than a good "normal" version, but nothing more. It's more about the trick bits. Better frame, stiffer swingarm, better clutch and ignition. Very very small differences, that all but a top level racer would ever notice.

Still great to have though.
