My bike (a brand new 2009 Yamaha XVS650 Classic cruiser) will probably be going into the workshop next week. The strangest thing (well, strange for me anyway). Being a learner, I've been practising emergency breaking. It seems that after an emergency stop, something goes wrong with the bike and it splutters and coughs as I roll on the throttle after changing up from 1st to 2nd and from 2nd to 3rd. It threatens to stall. Giving it a lot more throttle (cough, cough, splutter, splutter, recover), or pulling in the clutch nearly always rescues it from the stall. This behaviour happens every single time I come to an abrupt stop then take off again. Weird.
