Im wanting to do the AF build using my 85 c5, but all the builds ive seen, the pipe used appears to be a newer style, say 93. My question is, will this style of pipe affect the running?
Are you asking if the new style pipe will work on your 85? Yes, it works fine. And it is really your only choice to fit the new aluminum chassis, unless you have someone that can hand fit a cone pipe.
I worked as a mechanic for several years on cars, but 2 strokes are odd to me. I know that the shape and size of the pipe can affect the running of the bike. Thanks for your input!
