Is your Weril the older kind with a thin brass rod that functions as a valve guide? On mine I found that the rods were wearing due to rough edges on the hole in the top of the piston that the rods slip through. Somehow that wear caused an increase in friction. Newer Werils have more conventional "key in groove" valve guides like the ones on Yamahas.
