I couldn't find the specific forum to help with engine problems. So here I go.. Sunday the 4th Me and some of my friends took a bike ride to Hartside cafe, but unfortunately my bike broke down on the way there and finally gave up the ghost at the actual cafe. Whilst I was going around a bend pass Alston my check engine light popped on and my power cut. I had to ignite my bike again to get the revs up. It said I was doing 50MPH all the way there with 6000 revs. Whilst turning into Hartside cafe my bike cut out completely and didn't want to start again, so I had to call my father and his friend to recover it. It's not a problem with the battery or sparkplug nor the air filter cause Friday I changed oil and gave it a new sparkplug and air filter & the battery was new February time. I've had the bike for a year now. I also checked the Battery cells and checked if the sparkplug is sparking fine. The bike is a YBR 125cc 2009 Roadster Fuel Injection Fuel seems to be going through the injection head fine but this whole thing has me confused Any idea what's going on with the bike? Also the bike's engine is turning off going CHUGCHUGCHUGCHUG But when finally starting the bike you need to keep it above 2000 revs for it to work otherwise the bike cuts out
