Here goes, I had an old timer BSA guy tell me he used to install the bulbous end of a medium sized cotter pin, into the oil return pipe in the oil tank, and then bend the feet around the tube to keep it there.  This creates a little more resistance to all of the oil going back in the tank, and sends more oil, (the old timer said 25% more) up to the rocker arms.  I asked Musky and bsa-bill about this.  They both agreed this was probably not a good Idea.  BSA did not do everything right in their manufacturing, but this oil feed factory made restriction must be right on, look how long it has worked for these bikes. REMEMBER also that originally the upper oiling was relying on the oil splash system.  Have you ever run your bike with the valve covers taken off and observed the goings on, well there is oil splashing every where, it gets thrown off of the tappet adjusters, if it is working as designed there is plenty of oil up there.  bsa-bill said sure you would have more oil in the cam trough (drains down the push rods to followers and cam) so no danger of starving the cam bushes for oil, but the PRV is designed to do just that.  Musky said he would be concerned that there might not be enough oil for the scavenge side, of the oil pump, to cope with it.  Both of these observations by them are very valid positions. It harkens back to >>  "if it is not broken do not fix it" .  NUFF SAID, please comment back on these observations, from your experiences with rocker oiling's.

Bill and Bill, Yep, can agree, took my tappet covers off to check how things were going quite a while back and soon had an oil splash zone around the bike that proved beyond dought that the oil was getting there ( thankfully )!! don't intend to do it again anytime soon , BobH.

Just to digress slightly. What internal diameter should the oil lines on a 1960 A10 be, 5/16", 3/8".?  I thought they were the smaller but someone told me they were 3/8?
Thanks

Hi. I run 5/16" bore oil hose on my A10, and make the hose assembly with barbed type connectors which allow hose to simply push over, for extra security you can add hose clip.
