Bike is a 1997 D2 model. I need to know how much each side, and what grade please. Anyone got a clue, cos I don't. -- Lozzo GSX-R1000 K1 "You're a sci-fi gyppo" (tm) Kelly Forbes (aged 9), May 2005 >> Stay informed about: GPZ500 fork oil.

I found that before, but it refers to the A model up to 1993. Mine's a 1997 D2 model[1] [1] Actually an E2 Italian import with twin discs, but the inner fork and spec is the same. -- Lozzo GSX-R1000 K1 "You're a sci-fi gyppo" (tm) Kelly Forbes (aged 9), May 2005<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: GPZ500 fork oil.

Good job I've never changed my fork oil then. Too right. Each lkeg only holds 290ml. There has to be an air gap at the top. The usual scenario with Kawasaki is that they don't give a quantity, they say to fill the fork leg to a certain distance from the top when the spring is out and the forks are compressed. -- Lozzo GSX-R1000 K1 "You're a sci-fi gyppo" (tm) Kelly Forbes (aged 9), May 2005<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: GPZ500 fork oil.

The forks are only partly filled with oil, though, and the bit with the hole is down the bottom end where the oil is. The point being made was that if you filled the forks completely with oil, the forks wouldn't compress at all, because oil is incompressible. You need an amount of compressible air in there, and this air also acts as an additional spring. -- platypus his tongue was swollen with devil's love<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: GPZ500 fork oil.
