Opinions on lock up clutches


Recommended Posts

To use a lock up you will definitely want tranny work. Not so much if you use it the way I do on lower power trail bikes, but for anything making 65+ you will want some type of stock cut of some sort at a minimum. Doesn't have to be an over ride. As for shifting it at WFO, when else do you see big lock up drag bikes shift?

I am running a 421 cub cast, 165 psi, 35 Pwks, shearer pipes, stock trans, shifter star and pro shift roller. Maybe a lock out is not necessary? But I do have all apart cases split. Pro trany mod or just throw new clutch every few years?
