I think you're likely to find a failing coil or excessive resistance in a plug cap. The gray ignition modules are pretty robust, but sometimes (infrequently) go bad.
Hello from Atlanta, Georgia, USA
Hello all. Been lurking for quite a while now but figure it's time to sign up.
About me: I'm an ICU Registered Nurse at a big Atlanta hospital. I bought a 1983 Suzuki GS550 when I was 17 years old and have had about 15 bikes since then. Most of them Japanese and most of the standard street bikes. Last running bike was a KLR650 that I rode for 7 years and about 70k miles including a few big trips. The motor died right before my son was born 3 years ago, and I haven't ridden since (except my Yamaha Zuma 125 commuter scooter).
About the bike: Met a guy about a year and a half ago that was looking to clear out his garage in preparation to move. He heard I like to work on motorized things and made me a deal I couldn't refuse. He'd let me have it for $200 if I could get his 1982 CX500 out of his garage that day. Hadn't been run in 5 years or so. I brought it home, put in a new battery, spark plugs and cleaned out the fuel tank. That's about as far as I got before Covid got crazy in Atlanta and I started working a lot of extra shifts. Just now getting back to resurrecting this old girl.
It will start and run, but intermittently drops the left cylinder. I'm gonna get in the shop tonight and start troubleshooting with the help of all the online resources for the CX500. I'll start another post as I start to dig in to the old girl.
