The rear piece of cable housing you installed, is it linear indexing housing or standard spiral (brake) housing? Being a friction set up, using spiral housing may be in your favor.
actually the mechanic at the LBS installed it. to make a long story short, or long, i took the chain off the bike to give it a good washing and lube. I went down to the LBS for a quick link and we found that none of the links they had would fit the original chain on my schwinn. I told the guy to just throw on a 6-7-8 chain that they carried and be done with it. Then he talked me into the new cable and housing, telling me it would shift so much better. And he was right, it definitely shifts better, but now i am getting the ghost shifting.
im sure the housing he used is for indexed modern bikes...did not know that would make any difference, and stupid me, i didnt even save the original piece that came off the bike!!
I'm going to try to tighten up the shifter tomorrow. we will see...
