So I just tuned my stock 2-shoe clutches on my kitted 1980 Puch Maxi e50 and all I can say is wow what a difference! Before my bottom end sucked but now it just flies off the line and engages fully around 22-23 mph. What worked for me is I turned the adjustment screws 4 1/2 turns in from flush (using stock springs). Easy as pie doing the entire job. Much more fun to ride after doing this mod. Highly recommended if you are running a kitted Puch
