+10 Gunny dito.+1: Neil & Walt are right on, 1st gear for slipping and solid engagement for the rest!^^This.There really isn't any need to continuously slip the clutch in any gear other than 1st.Clutch slipping is for slow speeds only.
I never have a need to slip the clutch on the Feej, except starting off. In the dirt (on my dirt bike), that's another story. Roost on mates.
