I have new bodies for my V-One and I'm wondering which is the best solution to balance engine ventilation and aerodinamic.

I used to make a hole on the front glass in the middle-high position and to remove the front/side glasses and completely remove the rear glass.

Some advise needed...

This is correct. I think that you'll also remove front left and right glass.

yes..normally the front hole( for fueling purpose) and rear hole (for engine ventilation/cooling effect) , the front sides window (both sides) . but some says leave the front sides window for better aerodynamics.

Thanks for your suggestions.

My doubt is mainly relevant to rear glass, if to remove it completely or to just open a hole similar to the front glass one.

I've heard different opinions on that...

well if u remove the whole rear glass, for sure more ventilation/airflow that allows more cooling process to take place. if u remove smaller portion of the rear glass then less air flow . for me to be on the safe side i prefer a lot more air
