Great forum - glad I found it.  Haven't been on a bike for quite a few years, but I quess you might call it mid-life crisis?  It was either the bike, and old Mustang, or a new girlfriend.  The wife opted for the bike.
I just got a '78 750K that's in pretty good shape - only 18K miles.  I plan to fix-er-up, sync the carbs,  replace rubber parts, etc.  A friend told me SAE oil specs have changed quite a bit since '78 and instead of the recommended 10W-40, I should use a 20W-50.  Thoughts???

Thanks,
