    Clutch cable length.

    I recent,y purchased a 1970 cb750 bobber and the bike runs nice but the clutch cable is a mess and needs to be replaced. The only issue I have is that the bike has 12 inch apes on it and I do not think that the stock cable will be long enough. If anyone has any ideas it would really help.
