    Was sumping after removing suction check ball like everyone recommends so drained the 20w 50 out and put a petcock on bottom of oil tank. Had a few quarts of sae 50 on shelf and put in. I'm walking on bilateral knee replacements so need all the help kicking I can get. The trans/ primary runs cheap sae 30, it's throw away oil with chips the crash box makes. Went full synth route on other motorcycles and while recognized as superior lubricant it does have the annoying side effect of seeping through paper gaskets. My opinion now is run your favorite flavor dino oil and change often.

    Removing check ball was only recommended for N.Y/police bikes for winter. Remember the oil in tank does not run that hot so multi grade entering motor may not shift to higher weight in a timely matter.

    It's in Kiwi's parts book to remove the second ball in 48 oil pumps and others do recommend. It'll work either way, ball is pulled off seat by pump suction but it does sump quicker without. With the ball it takes all winter to sump versus a week without. Always been a believer in Smokey Yunick who claimed 90% of engine wear occurs upon startup when oil is not reaching all parts, makes the case for lighter base stock and molecule expanders that react with heat. New motorcycle riders with multi-vis hit the magic button and go right to 60 mph with no side effects from slow "shift to higher weight in timely manner". However, old guys like me raised on straight heavy oil never lifted a kickstand until the fins burned lines in your hand, then the oil was getting through, straight weight or multi vis.

    I run Brad Penn Penn Grade SAE 50 in the engine and Joe Gibbs HD50 (SAE 15-50) in the primary and transmission.

    Brad Penn is no more, called Penn Grade when DA Lubricants purchased from ARG in 2015. Still made at the old Kendall refinery in Bradford PA but suspect much of the crude is hauled in by rail. While true that PA crude is green in color there just isn't enough left and the analysis of PennGrade shows green dye. Nevertheless, it is excellent oil and never a mistake to use.
