I have a 92 FZR1000 that I have just bought 2nd hand, it has covered 55000 km´s and I have just replaced the front fork seals/oil, it has a new Pilot Power 2 and a good rear tyre. She handles like a pig, inspires no confidence when turning in and the front end is skittish over mid corner bumps. My memory of these things is that were much better than this and at least on par with the GSXR11´s of the same era??? Standard fork oil is 5W, I am running 15W - could this affect it so drastically. Cheers.
