Hi fellas, any one out there have any opinions on soldering a new 3/16's outside diameter oil pipe onto the Banjo fitting on the return side of the oil, on the back of the oil tank. This feeds the return oil to the rocker box. I have had 2 different schools of thought on this, one Brit fella that now lives here in the U S , and works at an Ace Hardware Store, rode nothing but BSA's in his youth growing up in the U K. He told me soldering this oil pipe into the banjo fitting can be done with regular plumbers solder, 50% tin 50% lead. He also said unless this fitting gets over 300* degrees F. that this solder is just fine. I have used it for 40 years when making up my cable ends. Now some have said I need to use Map Gas (hotter) and silver solder here because of the heat. I would like to hear from anyone who has done this either way, and had success or failure, and why it failed, or worked.
THANKS MUCH
