Good afternoon, I have acquired a poorly cx, its my first project, I'm modifying it with a monoshock and having a cafe racer style, I'm going to convert it to upside down forks and want spoked front and rear wheels, I've hered a gl1000 rear wheel is a possibility, what type and year would I need and what modifications would I need to make? Thanks, Jack 馃檪

Welcome, Jack!
Especially with this being your first project, get it into running condition first. After everything functions, start making incremental changes. If you start by cutting parts off chasing a particular style, the odds that you'll find yourself over your head and giving up increase tremendously.

I know I should start by getting it running, but there's all sorts I need to replace anyway and I know my dreams of what I want it to look like won't allow me to just get it running, I want a challenge and I am an engineer so have some expertise in some topics, any help is appreciated, thanks.

There is also the pain of spending a bunch on fun parts and plating and powder coat. Then when its time to fire it up it doesn't. then you realize it will need a complete rebuild and then that some parts are no longer available. You may not want to get it road ready but I would suggest you at least fire it up!

Welcome to the forum. Please add your location and your bike's model and model year (NOT year first registered as UK paperwork shows) 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).

And welcome to the world of antique vehicle ownership (they own us, not the other way around). Your bike is about 4 decades old and may or may not have had all of the maintenance necessary to keep it safe & reliable so it is highly recommended to download the Factory Shop Manual for your model (available through the CX Wiki - link in my signature) and go through all of the service procedures, regardless of whether your bike has reached the specified mileage.
I also recommend looking on all rubber parts with suspicion because rubber does not age gracefully. Check the date codes on your tires and replace them if they are over 5 years old no matter how good they look & feel (old rubber simply cannot flow around the irregularities in the asphalt well enough to grip, especially if it is cool or wet). If your bike still has the original rubber brake line(s) (should be replaced every 2 or 3 fluid changes = 5 or 6 years) I recommend shopping for modern stainless braided ones (they 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 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. 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.

One example of dangerous mods is converting a CX500 swingarm to a monoshock without adding serious bracing to strengthen it. It was designed to be supported by the shocks and putting the force at the end near the pivot will put large bending forces on it that it may not be able to withstand.

Don't get me started on wire spoked wheels. They are so inferior to Comstar wheels in so many ways that changing to wire spokes is a huge step backward for no reason other than "style".
