Hi so I just built my motorized bike and I love it except, I have to constantly adjust my clutch cable and flower nut to get the push button right on the clutch arm. I will have it set up perfectly and everything is tight like the cable screw then after some riding it feels like the cable stretches out causing it catch earlier not letting me use the clutch lock out on the handle bar. So I am constantly adjusting it. Is this normal ? And how do I fix this?
