64 flh, stock pistons, stock cam, linkert, running dual points. this is a strong motor, it seems to be timed right (motor runs great, plugs have a lot of miles on them and are good color), bike loves to move on the highway. it's just one of those bikes that takes a lot to kick over, but why?
friend has mentioned that maybe - maybe - there is too much oil sitting in the bottom and that is creating extra drag on the flywheels. does this sound possible, and what could be causing it? someone else said maybe bad check valve in the oil pump, but another person said possible that the "plumbing" isn't working correctly and the oil is not being routed out of the cases efficiently (breather valve issue? do they get clogged or gummed up?). volume of oil coming out of primary drain vent is what you would expect and the overall oil consumption is normal.
please give me some thoughts/ideas. we pulled the plugs and kicked it and it goes through very easily, but once the plugs are in it's serious compression. thanks!
