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.

It's getting colder and I'm trying to get s jump on plans to rebuild my dual shock GPz. I'm pretty sure I don't want to swap the forks or swing arm.

I have some ZRX shocks on it already. What would be the best way to freshen up and upgrade the front suspension without retrofitting something from a new model?

Swapped a warmed up 82 GPz1100 engine into it also. The thing is an absolute blast to ride. Handles like the 750 but has over 100 HP, weighs 420 pounds and is wicked fast. If you got any ?? let me know.

Sooo, a KZ1100 engine fits in the GPz750 frame? I've heard it won't work, but I never tried for myself yet. What mods are required?

Hi Scubaanders.

Have been reading your thread as I'm doing something similar and have had some of the same issues. My base is a 750 zephyr and I have a ZRX1200 swingarm in it now. We faced the same issue with the pivot bolt being seized so the zephyr arm had to be cut out. I'm now getting custom shocks made, but I'm not sure on the difference between the zephyr750 swingarm and the zrx1200 when it comes to the pivot to shock mount dimension. I can measure the new zrx one no problem but I have no way of measuring the old one as it's scrap!

Would really appreciate if you could do a measure of your zephyr 750 swingarm. Center of pivot to center of shock mount.

There would be a bottle of whisky in it for you if you ever came to Australia! Nothing less than 12y/o of course

ZRX shocks

Zrx shocks are 30mm longer than stock.

Nevermind, found ZRX 1100 shocks and they look like they will fit. Trying to buy them now

Thanks so much for the kind words. I want to get a picture in sunlight this weekend. Really brings the color out. Do you mean the cost out the door on the shocks? I think it was $634 shipped.

So here are a couple of shots. Couldn't wait so I quick threw on the forks and swinger. I think I like it.....

Up close....

And with the rolling stock......

Need to do some "cleaning up" of the powdercoat before the shocks can go on, etc....
