Hey, does anyone know what the three holes are for at the bottom of the front frame rail of a ('81) CM400 where it connects to the front of the engine? Reason I want to know is, I may mount something there that would block 2, or all 3, of the holes and if these holes are to let all air in to cool the engine then I wouldn't want to block them. Thx for your help. See picture:

No special purpose that I know of, maybe to save a little weight? Blocking them will cut a minimal amount of air flow.

Moved to SOHC Frame section
