Thought I'd try to pick the brains in this forum. I own a 75 Z1 900 basically all stock, finished restoring it last August. The suspension on this bike is horrible, alot of people perform suspension swaps from newer bikes (ZX, GSX-R), but I'd like to try to improve the stock components. I saw Race Tech make a Cartridge Emulator, I'd just like to see what other options (if any) I have. Maybe even swap internals from another fork? Main problems with the suspension are the forks are too soft and dive under braking. You get a nice jolt on small, high speed stuff like an old expansion gap in the road. The rear shocks are sealed and basically just keep the ass end of the bike up. There's no dampening what-so-ever for the shocks. I know for the shocks I will probobly have to replace those. High speed cornering, 45+mph, the bike weaves. I also had an experience once on a straight away doing approx 85mph, the bike weaved side to side like the ass end wanted to go faster than the front. Not a harsh weave, just a gentile swerve but large enough to let off the gas. The steering bearings and swingarm bearings are new/perfect condition with no play. Wheels are straight and tires are new. So I'm hoping that upgrading these parts will make the bike more rideable without sacrificing the original look of the bike.
