It's a 1970 sohc .... I cleaned the tensioner during the rebuild, not sure of the adjustment process. Also, is the hole in the end of the piston housing supposed to be plugged?
I'm very frustrated with this problem, but I would like to know more about the fuel line arrangement out of the gas tank on my 1970 CB750. I have a very low (60 miles or so) effective range because when my fuel level gets lower the engine stalls because of low fuel flow, I switch to reserve...
