Does it spark well when its ice cold for hours ? Check your coils if possible ?
To start the bike we need 3 things = Stator Signal (crank spinning) , Injectors firing and ignition coils firing the plugs nice and bright
I would be suspicious of the stator ? It is easy to put the wrong one too or that the pulse sensor seems to hate the cold (ECU thinks dead signal recieved = cut sparks)
Your wobbling = Find out what cable wires are moving and check them (eg ? Clutch Switch sensor, KillSwitch Plug under air box could be covered in crud/dirt ?)
