I just got my f7 back from the dealer for the oil pump update and recoil. I was running about 80:1 with about 1200 problem free miles. My worry is that now with the pump full bore will I start to have performance/plug issues? I also had them install some Spectra rope instead of the regular rope. The dealer said that they have been putting the ski-doo ropes in because they are better than arctic cats-I refused to have anything ski-doo on my sled. I noticed that when I pull start now that it is not smooth-its very choppy-has anyone installed this spectra rope and experiencing the same thing or is something wrong?
