Hello fellow JH600 riders,
Do you guys have problem with your JH600 stalling sporadically? With mine it usually takes place when I downshift from 3rd gear to 2nd or when i first cold start it. When starting it cold I have to give it a bit of gas to maintain the engine revolution above 1800 rev or it will stall. Sometimes it stalls on me when I wait at the traffic light in neutral. This gets pretty annoying and can be rather dangerous sometimes. Once I was forced to abort a left turn attempt due to stalling and almost run over by a 4-wheeler behind me.

The local Shanghai service guy told me that this is a common problem with all JH600s and really not much I can do about it. "All single cylinder big bore has this same problem, including BMW's RS650". Is this an acceptable answer? Any feedback is appreciated.
