I was cruising at around 50 km/hr today and then I felt the power loss in the interval of one second. I pull to the side, and checked the oil level. I had an almost full gas tank. Continued half a kilometer at the stop,the bike wouldn't start up. I had to pull to the side again. I had to pull the throttle a little to start up the bike. To be safe, I pulled into the small alley and rode slowly on first gear, 20 km/hr, yet the bike gave up 50 m later; putt,putt,putt, then the engine died. I was in panic and didn't want to push the bike all the way home. Luckily, after turning on the choke and warm the bike up for 10 sec, the bike ran again. I did warm up the bike before riding. The first thought that crossed my mind was the battery or the spark plug. Anyone had this experience? I will get the bike checkup asap.
