vapor speedo

I have just fitted a vapor to my BRP, yet I can't get the tacho setting right, does anyone know what the pulse setting is and the wheel diameter is (so I can check my measurements)

Did you get a book with it because there is a few different ways of doing the speedo. With mine for the speedo I marked the ground and the front tire, rolled it for 1 revolution then measured from the mark on the ground to the mark on the tire after one revolution. The distance in millimeters is your tire size. You should be on the bike while doing this for accuracy according to the book.

with supermoto rims (17'') i got it set @ 1884 and with the tomtom rider added it counts the same speed as the vapor so it must be good with this setting but i think you need to know the setting for the original 21'' rim?
