Does anyone remember the correct ratio for the speedo driven off the countershaft? I hate to have to count the revolutions at 4123 RPMs at the countershaft and meaure the diameter of the rear tire and so on and so on[:o)]. Truth is I have it written down some where and can't remember where[B)]. HELP.[8]

Ron,
It depends on what your final gearing is. The "stock" settings for enduro are:
125cc 14T countershaft, 54T rear Speedo Ratio W1.8
100cc 13T countershaft, 54T rear Speedo ratio W1.95
