Apparently lots of ZRX guys are doing it. They reckon it sharpens things up a little, loses about a Pound in weight and creates a load of space under the gas tank.
Any comments? ]]> 221 Thu, 29 Feb 2024 22:14:11 +0000 https://www.zl-oa.com/community/threads/interchanges-between-kawasaki-models.25513/ https://www.zl-oa.com/community/threads/interchanges-between-kawasaki-models.25513/ invalid@example.com (Rod Nock) Rod Nock
Can someone tell me if the 600 tank fits on the 900 frame without major hassle? Also please include any other options for forks, wheels, etc. I guess the Concours engine bolts in?]]> 39 Mon, 25 Sep 2023 15:12:39 +0000 https://www.zl-oa.com/community/threads/4-in-1-exhaust.25424/ https://www.zl-oa.com/community/threads/4-in-1-exhaust.25424/ invalid@example.com (Mike Dagenais) Mike Dagenais 20 Mon, 21 Aug 2023 05:54:42 +0000 https://www.zl-oa.com/community/threads/has-anyone-successfully-completed-a-usd-fork-swap-on-a-zl900.25701/ https://www.zl-oa.com/community/threads/has-anyone-successfully-completed-a-usd-fork-swap-on-a-zl900.25701/ invalid@example.com (katz) katz I read a couple of posts regarding front suspension swaps but couldn't find any about a completed swap.
I was just wondering if anyone had done that, and if so what was the donor bike and what kind of issues/modifications had to be done? I'd appreciate any info on the subject.
I found that picture online (see attached), I'm not sure where those USD shocks came from but I like it.

ZL900 Tank and Airbox information]]> 65 Wed, 22 Mar 2023 05:34:48 +0000 https://www.zl-oa.com/community/threads/looking-for-advice-on-installing-longer-handlebars-on-a-zl900.25745/ https://www.zl-oa.com/community/threads/looking-for-advice-on-installing-longer-handlebars-on-a-zl900.25745/ invalid@example.com (katz) katz I'm trying to figure out how to install longer handlebars on a 1985 ZL900. From what I can see the following lines/cables need to be made longer:
- hydraulic clutch line (hose, 1)
- front brake line (hose, 1)
- throttle cables (2)
- choke cable (1)
I'm not listing electrical wires since those are not so difficult to extend but I'm not sure how to tackle those mechanical/hydraulic parts. If anyone has any ideas or maybe has installed longer handlebars on their motorcycle I'd appreciate...

I'm back after a whole year. Bike runs fine, it needed floater level adjustment and carb sync which I coulnd't do, so it went to a mechanic. So far so good.

1. To the problem at hand. You all know how hot the lightbulbs get. As a result, the plastic bucket dries and cracks. Mine cracked a lot so I am planning to use some superglue to hold the pieces and then reinforce with polyester spread OR silicone glue from the inside. I hope it holds - feel free to offer suggestions....

First post here.

Picked up my zl900 15 years ago, back when I was 17. Fought with the carbs and air box for a couple years without any success before giving it to a buddy who pulled the airbox and did few other things to it. It ran great for a long time. Now, I know I need a valve adjustment, which I was around when the doc did mine, but I do not remember all of that and will most likely be scouring this site for info when I'm ready for that. Currently my issue is, I have gotten the...
