No questions for you (yet), more of a suggestion on that filter oil
I use Maxima FFT (Foam Filter Treatment), it gets really sticky and when it starts to 'dry' it creates a "web like structure" that helps catch every last spec of dust/dirt trying to enter your intake/carb

It's my favorite filter oil for many many years now... it has always PASSED the "White Glove Test" when checking for dust/dirt past the air filter... nothing but clean air makes it past my Maxima FFT treated filters
