I´m a newbe & just bought a 1985 v65 Saber. I rode a 750 Norton Commando 40 years ago, but I suppose I´d still classify myself as a rookie. My question is, Is it still ok to rige my bike if the shifter arm flops around as long as it shifts ok? Do I need to replace a bushing or something? Thanks for your imput, Love this site!
