I have a Yamaha YZF R125 and I am noticing that after it has been unused for several hours, such as after the night or after work, as soon as I start it, if I do not rev it a bit, revs gets really low and it switches off. If I rev it a bit for 10 seconds or so, then it can remain idle without any issues.

I am new to riding and hence bear with me, but is this normal for motorcycles? Or maybe motorcycles with small engines?


  • Sounds like normal behavior. Is there a manual choke on that bike? Maybe you could use that for 30 seconds to avoid it dying. – cory Apr 27 '17 at 19:25

Its not unusual really for a single cylinder bike to stall when cold.. As a cold single cylinder engine is in a rather imbalanced state until it warms up. If it were stalling once it was getting warmed up then that would perhaps require a little investigation/attention, but only just to perhaps raise the tickover speed slightly.
