Did some messing around with the bike today. Put it in diagnostic mode and started checking things out.

Got to diagnostic 3 using the FSM as a reference to check out each one...

03

Pressure difference
(atmospheric pressure-intake air pressure)

Displays the pressure difference (atmospheric pressure intake air pressure).
Engine stop switch is on.
* Generate the pressure difference by cranking the engine with the starter, without actually starting the engine.

10-200 mmHg

So I was getting 6-8 haha. Hmmm. Did it while bending the vaccum line and got it to throw a code for the Atmospheric Pressure Sensor. The failsafe action according to the FSM is to set the pressure to the "standard."

Was going to see how the bike ran with this failsafe but had to go do activities lol. Feels like I'm getting closer haha.
