Hi Fred, I tend to agree with Hartmut and John on your brake situation.
Before replacing your tach, I might suggest that you make the relatively small (currently $36.50 at Spruce) investment in an optical tach so that you can see where you currently stand on accuracy. Cheers, Bill Fred said: I need some input on whether or not the master cylinder upgrade would be a worthwhile improvement with the original brakes, or would I be better off spending the money on some other upgrade (I am also thinking about a vertical card compass and new tach). All opinions are welcome.
