D&D (Pensacola) did my BB. I talked with Dink (owner/service manager) about the pistons prior to the work. He assured me that the high compression ones would be fine on premium pump gas. I ended up going with the Wiseco 10.5:1 and have been running mid-grade with no problem at all for over a year since the BB.
The bike is running the best ever right now after some carb tweaking. One of the reasons I decided on the Wiseco was my goal (which I told Dink) was the most torque I could get in the middle rpm range. I didn't care about Hp at redline. They ran multiple dyno runs. The result was 65.54 ft./lb. at 3408 rpm. I couldn't be happier.
