Hi all, I'm riding a 2011 Ultra with the stock 96ci engine that I've owned since last year. I'm considering the purchase of a big bore kit to bump it up to 103. Before I go to the dealer, I thought I'd run a few questions by you guys first: First of all, is the increase in power/torque so noticeable as to be worth the cost? Speaking of cost, what am I looking at approximately? Will it negatively affect fuel consumption? I upgraded to Screamin' Eagle Fat Shotz pipes - will I have to change them? Will I have to change the oil cooler I've installed for the 96? I bought Harley's long-term warranty - will this be affected? Any advice/comments would be much appreciated. All the best!
