Oil jets

(1/4) > >>

Rob62:
I was chatting to a guy at the Mallory festival of 1000 bikes a couple of weeks ago. I was telling him about my CB750 project. He asked me if I knew that the oil jets needed to be drilled out to a larger size than standard to ensure they dont block up. I said I hadn’t read about it but I did know that they can become blocked.... he seemed quite confident that it was a common well known modification. What do you guys reckon?

Trigger:
Never enlarge a oil jet, this will reduce the pressure in the bottom end  ;)
It is not called a restrictor jet for no reason.

Rob62:
Yes, it'll certainly reduce the velocity. You ever come across any enlarged jets trigger?

Drilled out jet on the left, original on the right, and the crank was the result   >:(
