As many of us i belong to several trike sites(facebook),so i have seen this at least twice.On two different trikes people with 2020's have had their clutch handle go flat aka no clutch action after riding for a couple hours at 70 mph in temps of upper 90's to 100 degrees.Once they let the bike cool for a little while the clutch handle returns.Wonder if this could be heat from the cat boiling the hyd fluid in the clutch.Has anybody else had this issue.Now my 17 still has the cat and it gets very hot but have never had this kind of issue yet.
