Hello, new member here.
Great forum; my question is about the lifters in my 86 fxrs (stock except
for single fire, S&S carb, T/H pipes)
About 10 years ago I replaced bottom jug gaskets and reused the stock
pushrods with no problems.
My rocker covers long ago shed their clear coat skin and recently the
rocker box gaskets started leaking so I pulled them off and got a set
of chrome (3 layer) from J&P.
I think it makes sense to use adjustable pushrods (probably S&S c/moly)
but I am confused about the lifters in this motor. The CSM - crummy
service manual - says the stock rods should spin after bleed down when
the cam is unloaded. I'm pretty sure this was the case the last time
I put it together. This implies no preload.
The tech tips here spec a preload of .05" to set up hydros.
The question is: Are the stock lifters some kind of hybrid design that
get set up like solids?
Thanks
