Got a manual? Either the HD Factory Service Manual or the Owner's Manual should list that.
Not sure if that bike has the cartridge in the left side or just a straight setup. My UC is spec'd to measure the air gap above the fluid when full. My Dyna ('91) takes around 11 oz. in each side.
Hey, Thanks a lot guys for the replies. I am going to change it over the weekend. I am going to try and measure what I take out also to be sure.
Thanks,
Ron
