    The value is in the drive shaft housing & gear case. That value is dependent upon the feel of the gear mesh & ratio 1:1 or 16:21.

    Chuck is correct it is a MK25 block, probably no pads unless it is a block with the single pad. It has a MK25 flywheel but has a MK 20H Carter N carb. The stacks & filler block, if there is one might be an asset to someone.Depending on the variables mentioned above, price range $800 – &1500
