Title: Speedo for Steel Tanker
Post by: firstturn on November 16, 2004, 08:33:23 PM
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
