First CX500

Welcome to the forum. Please add your location and your bike's model and model year to your profile so that you don't have to remember to tell us every time and we don't have to keep asking when you forget (see Forum Settings link in my signature).

I guess I don't have to welcome you to the world of antique vehicle ownership (they own us, not the other way around) or to tell you to look on all rubber parts with suspicion because it does not age gracefully. I'm sure you already know to check the date codes on the tires and toss them if they are over 5 years (old rubber simply cannot flow around the irregularities in the asphalt well enough to grip, especially if it is cool or wet) but a surprising number of people don't know that the original rubber brake line(s) should be replaced every 2 or 3 fluid changes (= 5 or 6 years) while modern stainless braided ones last practically forever and double the life of the fluid.
And don't forget things like the rad hoses and the boot between the engine and swingarm (they can crack on the bottom where you don't see it).

The Factory Shop Manuals for these bikes are available through the CX Wiki (link in my signature) and are among the easiest to understand of any factory manuals so aftermarket manuals should be considered secondary references at best.

The best advice anyone can give you about customizing any vehicle is to get it safe & reliable in more or less original condition and use it for a while before you start making any changes so it can tell you what changes it needs to make it do what you want/need better (I know that boat has sailed for yours but I would still try to put it back as close as is reasonable and ride it for a while before digging in too deeply). That approach almost always results in something you actually want to keep and use but making changes based on style or on what someone else (who may or may not really understand how the changes affect the way it works) has done often results in a piece of expensive yard art that you can't stand sitting on for more than a few minutes and might even be dangerous.
