Finally got around to getting 4" risers with 1 1/2" pull back for my '11 Superglide. Was looking at things close yesterday and I don't see how some cables will reach. Maybe they will once i get into putting the risers on. What do you think? Will I need to get longer cables? If for sure i will, i wont even start on it until i get them.--thanks

 

Not sure on yours, but it seems like re-routing will often times give you more room.
What did it come stock with?

 

I did the same on my stock 86 FXR and had to rewire to make things fit properly. I actually added an extra 3-4 inches and wrapped it up inside the headlight which served me very well as I have been able to swap out to a longer set of bars last year without any issues at all.

I custom wired using trailer fitting 7 core wire. Works well.
