I finally removed my 6" tubes and installed my oem tubes back on, the oem's are 24&1/4" from end to end without caps and sliders.
FYI the 6" over tubes were only 29&3/8" long so they are closer to 5" over in my case.

Here's pic's with 13.5 shocks, stock tubes and 5 degree cups and the bike
still sits pretty level.

 

I have a 'Seeger' kit on my bike, 13 degrees and 8" in length added, and I love the way it rides, there are some on this site that are very verbal about these kits but I can attest that bikes with these kits ride great going down the expressway or just cruizin. The funny thing is most people (bikers) that have seen my bike like what they see, its the so call real bikers on this site who have a problem with it.
