Hello all. My name is Chris and I've been reading your forums for a few months. I apologize about this being my first post. Let me tell you what I have going on.

2014 Tuono aprc w/almost 19k miles
She has been flawless except replacing a stator about 2k miles ago, and I love her. I went out to start the bike the other day and turned the key....everything was normal, the dash powered up and tach cycled........I pushed the start button and hear a click and the starter almost engages but doesn't turn over.....then everything blinks out like I turned the key off and back on (but I didnt). I try again.....does the same every time. I replaced the battery hoping it would be that simple.....same thing still happens.

Any help or insight would be greatly appreciated.
Thank youp we
 
Ok
starter motor u/s, bad earth, on battery or engine to chassis, Can you turn the motor over by hand?

When did it start doing it what have you checked it can't be that hard to identify the issue

Ignition on yes
starter relay ok as you say its trying to engage
dash board goes off when the starter try's to engage then comes back on when the starter has no load on it this is a symptom of a poor battery, low capacity or bad earth of high resistance in the starter motor or mechanical resistance in the engine (seized motor).
will the engine start using a slave battery with jump leads? Try using 1 jump lead from the battery negative to a good clean point on the frame or engine.
 
when you replaced the stator did you make sure there was a good connection at the multi plug , and have you checked the charging voltage , should be 14 ish volts

I restored a gt 750 kettle years ago and had a similar prob , that was down to poor earths and poor connections in the wiring loom .!!!!

also try and do a drain down test with a multi meter to look for battery drain .

and finally do keep the bike connected to a trickle charger as the ecu is always running in the background powering the clock , imobilizer etc etc .
