May be old..but all the same..

As mentioned previously I'm looking at buying a zxr750rr from 91.
These were a bit special and the Superbike versions did well in the hands of Scott Russell with the Muzzy supported bikes.
First things first with these bikes, leave the engines as they are but drop the excess weight, like the standard exhaust to a racing version and of course if the wallet permits some lighter wheels.I had Marvics on my last race machine and indeed Suzi 1100 WT Vance and Hines and the difference was massive in rep weight.
