Had to jump onto this thread. Below is my $400 94 ZXR400. I bought it from an ex-Navy girl. Motor was rebuilt before they dis-assembled and shipped from Japan in boxes on Uncle Sam's dime. Brand new Pilot Sport HPX on the back and very good tread Dunlop Sportmax on the front. So far I put a K&N air filter, oil change, turn signals and a Dunlop out back to match the front and migrated the HPX to my Ninja 650R. The front forks were lightly pitted so I am scrapping them for a 2004 636 front end with radial brakes. I keep finding loose and missing hardware as I go through it. Track day on the Oct 25th.... This may be a short lived beauty.
