Ok Grey Beard, ya got me.  Living proff that if you hang around long enough you will see and hear everything. 

That being said, I was planning on mounting my Magnum Cylinder head down.  There is an old thread in the Kit Building forum on a Tiger 60.  That fella built a cowl around his engine and inverted it as well.  It looked so clean.  Lemme see if I have this right.

An inverted 4s would be mounted with the carb slightly lower than the fuel tank centerline.  Correct?  </p>
