I have always appreciated the width and depth of advice provided here, so I'm going to throw something out and look forward to input. On December 19th I traded my '06 CUSE for an '09 SERG and have no regrets. The SERG keeps me in the CVO family, but I'm going to sell my '07 SERK in February and buy an '09 Ultra Classic (not CVO). My question here has to do with putting the 103 Big Bore Kit on the Ultra and the possibility of using the mufflers that came off of the '07 SERK on the new Ultra.
I read in the P&A Catalog that you can put the 103 Kit on an '09 Touring Bike at the time of delivery and maintain your standard factory warranty. It also appears that mufflers might be a part of that 103 Kit. I like the look of the 4" mufflers that came on the SERK.
I went through D&D Fatcats, K&N High Flow filter, SERT, and dyno tuning on my '06 CUSE and '07 SERK. I've been there and done that and really have come to enjoy a quieter ride and don't care about squeezing out a few more horses and foot pounds. I don't want to have any warranty questions on the standard warranty (or possible extended service plan).
I'll look forward to feedback!
