Hello everyone I bought my GL500 silverwing last year and started getting everything fixed on it to get it back on the road. Is been rough as the bike dies every time it's put it gear. I'm hoping to have Murray rebuild the carbs.

Welcome to the forum. If the bike has been sitting for any length of time the fuel system is suspect for sure. Make sure you check your tank for rust/debris in addition to having the carbs serviced. Make sure you download the FSM and check the timing chain & valve clearances as well as inspecting all the brake components. SCBob should post something shortly that details some other points of interest. Here are a few helpful sites to look at.

Factory Service Manual - Honda CX and GL Wiki (motovillage.org)
The Honda CX and GL 500 and 650 family of motorcycles (motofaction.org)

Good luck!

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 too) 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).

Re the stalling problem, a couple of things come to mind.
You are squeezing the lever to disengage the clutch before you put it into gear, aren't you? (If you are an experienced motorcyclist this may seem obvious but we do get people who have never operated a manual transmission on occasion)
Assuming you are using the clutch properly, is it adjusted correctly? If it is dragging there will be load on the engine as soon as you put it into gear even with the lever squeezed.
What is the idle RPM set at? If it is too low that could cause the engine to stall when you engage the clutch in gear.

I'm sure others will be along with more (possibly better?) suggestions.

Thank you for the welcome. I've been lurking for a while. I don't plan to ride on the current tires as I'm fairly certain they are the original tires. The bike has an actual odometer reading of just under 7300 miles.
I have changed;
  • Coolant and one of the seals in was leaking a little from the housing that holds the water pump.
  • Spark plugs
  • I tried rebuilding the carbs myself and with my rebuild the bike with start and idle but it jumps like crazy and I can't get them to sync.
New battery
  • Gas tank is spotless
  • all new glass fuses allot of them were rusted
  • in the process of rebuilding one of the front brake master cylinders and fully changing the fluid. Once I get it running I will switch to the braided lines
  • fresh oil and filter
  • new air filter
  • new grips

Need to do
Vavle check
Timing chain check
Murray carb rebuild
Seat cover
And other stuff I can't think of

You only have one front Master Cyc but may have 2 brake calipers. Rebuild both calipers, if you are doing one. Send the carbs to Murray for service. Don't even mess with them.
I found this out the hard way, I consider myself a decent shade tree mechanic but the dual carbs threw me off. all my other bikes have only had one carb.
