Fork upgrade alternatives to swapping?

For the RT site, go to Product Search and select your bike info. www.racetech.com/ProductSearch/2/Kawasaki/GPz750/1982

Thanks, Idk why i couldn't figure out how to do that. The price isn't bad at all considering.

I'm not having any issues at all with the rears but maybe I'll get the them to keep them on hand.

They are a little longer but work and aren't $100/ea from RaceTech.

Thanks for this info! Where are you buying these bladders, I've tried looking that number up on a Kawasaki parts site with no luck.

I found it on eBay right off.

Its a KYB number, not Kawasaki.

I've found them, thanks!

Did you guys do the lowering mod to your shocks? I forget the exact measurements but the ZRX shocks are like 1/2" to 3/4" longer. Mine we "useable" but with no weight on the bike I had contact between my muffler and axle. I did the lowering mod by cutting off the original preload nubs on the shock, ran that for a bit, then found the inner sleeve flopped around. I wound up welding the inner sleeve and outer preload adjustment ring together. That's when I did the major overhaul on them.

Also, I just spaced theleft shock out with washers to clear the chain guard.

I got them specifically for the extra length. I had extenders before.

My muffler doesn't go back that far and I don't currently have a chain guard.
