2006 Hyabusa - Cranks won't start

[RedBull]

Cranking pretty fast to be 12v starting system .

Do a compression test .

Could be, and I said "could",
broken timing chain .

That's why "you should forsake all others and follow us" to Hayabusa kingdon!

Hahaha now that's funny stuff

Would’ve been nice to know the mileage on that 99 with compression so good.

Ok, tomorrow I'll have several hours to work on the motor.

I did have a chance to take the battery to the shop and it is fine. I really wished it was just the battery.

Knew it. Try an ecu

• I traced the O/W wire back to the Vacuum control solenoid and I have 12v there.
• I also tapped into the Grey wire at the ignition coils and i have 12v there also.
• Fuel pump is priming, I can hear it and I can see the fuel pressure on the gauge.
• The Y/G wire. No power to it until the key is on. Maintains 12v when the key is on.
• Fuel pump - When the key is turned on and it primes, 12v.

Here is the thing, at every 12v connection, does not matter if it is the grey ignition wire, O/W wire at the control solenoid, or fuel pump. Every time I depress the starter button it goes form 12v down to 9.5v.
Battery is fully charged when this happens. I have the battery back on a charger for the moment since I've been running it down.

Could it be the crankshaft position sensor?

Just tossing this up here.
