Old ZX12r wont start, advice for debugging
My 2000 12r has ALOT of miles on it, but really hasn't missed a beat ever - amazingly robust bike! Until now though.....
I'm suspecting the starter motor has gone. Here is what I can tell you:
First sign of trouble was just after a 30min drive. I turned bike off then decided to start it up again straight away but I noticed it really struggled to start. Like starter motor was struggling to turn engine. Bike was fine for a few more days of regular daily commute after that, but then failed to start one morning with following symptoms. Bike turns on as normal. Everything seems to happen as usual - the rev counter and speed needles do their test. I can hear the whine of (I presume) the fuel pump etc. Appears normal. When I press start button the engine does not turn over, but I do hear the same fuel-pump sound (or whatever that high-pitched whine is) as long as I have my finger on start button. Battery is not old, although not brand new either. I have taken it out, charged it, measured voltage with multi-meter (12.5V) and all seems good. Although I have not done a full battery test so can't guarantee it is that
