ZX600 Rear Shock Question

krbreton · June 14th, 2009, 03:49 PM

Hi All-

Based on the advice in the ninja 250 FAQ, as well as my current weight of 200 lbs, I decided to upgrade the rear shock on my 1997 Ninjette. I bought a 1989 Ninja ZX600 Shock off ebay. When I got it, I pressure tested it, and then drained/replaced the oil with 7.5W Fork Oil. However, when I drained the shock, I only got about 150mL of fluid out of the shock, including heating the shock body with a hair dryer. I then replaced an identical amount of fluid using a syringe.

I am wondering - Since the FAQ says that there should be about 285mL of oil in this shock, is there some sitting in the shock still, or should I assume it was underfilled and then top it off. How would I know when there is too much oil in the shock? Should I just fill it until it starts running out of the fill-hole? Should I try to drain the whole thing again, now that the fresh oil has been in there and see if I get more fluid?

Any suggestions would be helpful. I don't want to put the shock on the bike until I have it set up with the oil level correctly.

Thanks in advance,

Kyle

Did you try moving the shock in and out to try and force the old fluid out? Try that and then fill with the 285ml as reccomended.

Hey Guys-

Thanks for the responses. I'll stick it on the bike and work it through a few times, take it off and drain it, and then fill with the recommended 285mL.

Hopefully, I'll get a chance to have somebody check it out at the next Bay Area Ninjette ride.
