Well, my '78 honda express (NC-50) seems to be loosing power, or at least speed. After fixing all the latest problems, the express has a top speed around 28 MPH ON A DOWN HILL!! before i dont know how fast i was going on a down hill (the speedo maxes out at 35 or so). Any ideas? Timings dead on, carbs clean (latest fix) muffler seems pretty clear, I decarbonized the cylender about a week ago and the compression was around 95 Psi last time I checked about a week ago.
I seem to have just said i have a problems but nothings wrong, if you can think of somthing i havent covered, feel free to post.
