GREG H :  Like the hundred of dragsters I see weekly with the hose from the valve covers going into each header pipe on their exhaust with one way out valve [ like the PVC VALVE ] in older cars the exhaust pulls out the pressure in the motor thru the valve covers.  I made a set up like that for my 400cc HONDAMATIC drag bike and put the hose line in to the pipe on a 2 into one header with a PVC valve in line as a cheap vacuum system.
I like the sound of that set up  ;)

I thought I had some close ups but I dont
I drill and reamed a hole then welded the tube in place for the tappet
caps for #2 and 3
routed everything back behind the tail section

Nice set up Jim ;). I think that I've got a handle on what I'll be doing now .
