Hi All
I've recently bought a 1-1/2" Nippy crank (splash fed) that I intend on putting in the new engine I am building. When I look at it against the old 1-5/16" crank the oil ways and catch scoops that the oil jets aim lubricant at seem very small on the Nippy crank (see photos - Nippy crank with Con Rods attached, 1-5/16" crank without). Is this going to cause me any problems? Do I need to be extra careful about the aim of the oil jets? Has anyone drilled these holes out to enlarge them a little?
All advice gratefully received
Cheers
Robbie
