Ultima six speed question

[SnailTraX]

I am going to install an Ultima Six speed in a 94 FatBoy. Right now I am running a Dakota digital speedometer with a Dakota Digital speed sensor, mounted on the rear of the speedometer head, and using the stock cable to drive it off the front wheel. I want to get rid of the cable. I have read somewhere, that if you use the stock Harley speed sensor in the transmission, that you need to use a shim to raise it a bit when you install it in an Ultima. Is this true? Is this because the six speed has a larger gear in the case? Where do you get this shim? Who on here has installed an Ultima and used the speed sensor? Thanks, SnailTraX

yes, you need spacer to get speed sensor up a little so gear dont chew the speed sensor...

i am thinking about to swap the gearset for ultima 6 speed gearset but right now it is hold...

Where do you get a spacer? How thick? I am using an Ultima six speed and stock Harley speed sensor. SnailTraX

you can use normal washer but need measure how thick the washer is..
