They did make a retract setup that moved them closer, about an inch or so...good luck finding a set. Mr Wright MAY have the ability to produce a one off set.....maybe. He a busy guy. Other option is a "push seat". Padded heavy in the saddle seat to "push" the rider closer.
Curtis at wildsteedworx.com has 1.5" retraction kits. I remember when BDM offered these kits, they said they won't work with some exhaust systems. I'm not sure if this is the case with Curtis's kit or not. Give him a call. I'm sure he can help you out.
but, make sure you have the standard set and not the extended set before you try to put on a retracted set. as said above, a push seat make be your easiest route.
Like Mr. Woodbutcher said, Some things may be in the way, if your putting the re tracked control plates on. Take a picture of each side of your bike, so we can have a look.
