Morning all, I'm having a problem with my duke-125, that only seems to happen in even moderately warmer weather having been fine all winter until now. Whilst riding I seem to have a slight loss in the engine power not massive but noticeable, also when I pull the clutch in to either cost downhill or come to a stop the bike will cut out. Its confusing me because it may happen only 1 time in 20, but it happens every time I ride the bike (not in winter though) coolant looks fine so I don't think it's an over heating issue, also my heat gauge may only be a quarter of the way up, so its in no way scorching hot. Any ideas of the cause and or things to check would be greatly recieved
