It would apear that the Virago 250 has a single carb. which feeds both cylinders. So the idea now is to make a intake manifold for the VT500, then attach the Virago 250 single downdraft carb, but only after the aero project is finished.
The issue I am dealing with now is the conflict/interfearence between the exhaust systems large exits and the aero body work. What I have in mind is to remove the OEM two secondary "mufflers/resonators" and conect shorter/smaller exit tubes from the main central muffler, which do not interfear with the body work.
Update; I just finished removing the 3.5kg [7.7lbs] of stock exhaust parts that interfeared with the aero body work and replaced it with 0.5kg [1lb] of my home made exit tubes. so in helping the aero I have also managed to save 3kg mass.
