*Help* ABS dual discs to single disc.
*2009 Street Glide FLHX with dual disc ABS*
In reference to the front. I ordered a 21" 3.5 black powder coated front rim for my bike. I realize after we got it mounted and balanced to the brand new tire that I bought as well, that is meant for a single disc abs bike, meant for the rotor to mount on the left side. Obviously that means I can't return it, because I already mounted it and whatnot. So I am aware that because my bike is 2009, that I don't have to replace the master cylinder. However, my questions are, and ANY other information is welcomed, please:

However, my questions are, and ANY other information is welcomed, please:
- 1. Can I just cap / cut the brake line? If so how and where do I do it? Bleeding too? (If I don't cut and cap it, I'd have to move the whole line to the other side of the bike)
- 2. Do I HAVE to get the 6-piston caliper? Or can I use the stock caliper or a different one but less expensive than the 6-piston?
- 3. The 13" rotor I was told is better with the single disc, yes or no, is the stock 11.8 okay? Any photos for assistance AND any other necessary information in converting dual (abs) to single (abs) really appreciated!! I can't send back nor waste all this money I just spent. Please!

Whew, that other thread has an awful high ratio of BS to info... I would take a hard look at 14" rotor and adapter for factory caliper from Arlen Ness. Pretty reasonable price compared to other options and at least you retain a little more braking ability, and lets you use factory caliper. They also make a 15" rotor but I don't believe they have a caliper adapter for touring--would be worth checking out and Ness maintains good technical/sales support people available by phone. I'm not sure how much difference a 6 piston caliper would make, but the rotor size should help a lot regardless and I would be hesitant to shell out for a Performance Machine 13" rotor/6 piston caliper combo at almost 3 times the money and a smaller rotor, though they look sharp as hell. Re ABS, I wouldn't think that would factor in at all but would want to verify that from someone that's done the mod--as post on other thread mentions, ABS system doesn't know how many rotors you have so only issue might be the change in volume of brake fluid which the system already has to tolerate somewhat with difference between new and worn pads. I would think you'll end up replacing brake line from ABS unit instead of capping or splicing, but those might be options. Sucks you got the wrong wheel; personally I would go after vendor to make it right rather than sacrifice brake performance unless you don't care and would rather have that look, and don't mind spending extra to end up with less brake performance.
