I have an 05 Ultra classic that I am converting to an SG clone. My question is how do I eliminate the right side front caliper?

 

I did the same to my 04 Flhtc. You will need a master cyl off a Softail(single caliper).I think it has the smaller piston. Also I would HIGHLY suggest you buy a Good Quality 6 Piston Caliper and good pads. I used a Hawg halters and Lyndall z Pads and I would say i didnt lose much if anything with this setup.I also had rt side caliper mount on leg machined off .

 

did you need any kind of spacer on the right side since you took the rotor off?

 

No extra spacer neede ,just use what was there. I used ***** Shiny spacers which cover Disc bolts and cleans it up.I also used a machined old rotor for a spacer with these spacers..But as i said you can use what you have if your on a budget.
