Put it back together minus AIS , thanks to all the good advice on here , new plugs fitted , new coolant , new tank cover (supplied by Devilsyam Luke top bloke ), started it up to let it warm up , check for leaks and took it out for a 60mile first ride since HTB as the roads were dry , no new vibrations , no missing , very responsive , so I think I haven't focced it up , Removed battery when I got back .
