this last digit is just a variation of the part
 
Sometimes parts from different engine families are shared between families. Usually the first family to use the part will hold the family identifier. Like a 85-0102 is a idle needle for a RJL K.61 but it also fits a older K&B .61 and .40 carb. Since the RJL used it first the number retains the -01 in the K&B .61 and .40 parts lists.
Using this system you can sometimes make up a number and find the part you are looking for. Lets say you want a crankshaft for a K&B Sportster .20 - If you go to our shopping cart all you need to search be is 17-56 (omit the last 2 digits) and the result will be all the crankshafts fitting that engine family. This works only if the parts are not shared across engine families.
