    Just wondering if any one has converted an Ultima 6 speed or Harley belt drive box to chain drive? I am building a 250 rear end bobber and need to off set the final drive sprocket , but not sure if a spacer is required between the gearbox output shaft seal and the drive sprocket. Any help appreciated.

    Thanks

    The Ultma Box has the same Spline as a HD Box, so you just use a HD Sprocket. What Primary are you using and what Frame ?
    You need to Space out the Primary and depending on the Frame, you may need to move the Gear Box over. If it's a Stock Frame you can buy a Plate that bolts on to the Gear Box to move it over. If It's a Aftermarket 250 Frame the Offset Gear Box Mount would be built in to it.
