I've done some searching on this topic but can't find a direct answer. Are Omar's or Tarozzi's a direct bolt on on a '75 k model? If so will they work with the kick starter? The only info I found was on a '77 and they were not bolt on, needed some modifying, and also blocked the kick starter part way. I also notice that when you buy Tarozzi's you specify drum or disc rear brake. Is upgrading to a rear disc something I need to seriously consider? If so, I'd rather do that first before ordering rearsets so that I get the correct ones.
