Hi, my name's Michael; this is my first post. I bought a completely stock 1980 XS650 a few months ago for my first bike. Previous owner told me the engine was recently rebuilt. It's had been running fine and the bike would start first or second kick from cold (starter never worked great from cold). No pinging or any other weird noises or behaviors during those rides once I give the bike 10 mins or so to warm up. I've been putting 93 octane gas in it since I bought it.
Anyways, I rode around all day a few weeks ago. Rode about 60 miles of back roads taking stops every 30 minutes or so. Bike rode fine on the highway for about 20 miles at about 70 mph. Then, after I rode off the highway and into some traffic lights, my bike started to backfire and the power dropped significantly. Every time I had to stop, the harder it was to get the bike going again no matter how gingerly I controlled the clutch. Eventually, I couldn't get the bike going again and my friend carried it back to my place in the bed of his truck. I let my bike cool for a couple days and tried to start it up again. The bike would backfire and cut out under throttle just like it did while it was hot.
I dug around this forum but I am reluctant to dig into the carbs just yet, since I am not confident what problem(s) could have developed during that ride. Do you more knowledgeable people have any theories on what could've gone wrong? Thanks in advance.
