I haven,t checked voltage draw on my 16 V7ii (not needed yet) . It has sit for weeks w/o use & fired right up. So Kev M is probably on to something there. My favorite ABS quirk is when started on the ctr. stand , fluid drag allowed rear wheel to turn,slowly . This seems to confuse the computer and cause low or erattic idle, it also throws a minor ABS code. Not enough to trip the light but my local shop says they see it!
