We finished our 103" build this afternoon. We used stock cylinders bored to 103", SE 103" pistons, Heads ported/cc'd by Big Boyz, andrews 54h cams. Man what a DIFFERENCE. I am amazed that I am riding the same bike. We worked late so I only got to take it for about a 20 mile ride but that sucker has some pep to it. I am very anxious to get it out on the road this weekend to do a breakin ride to where I can actually start running it up a little. Man what a difference the heads/pistons made. I had the cams installed for a couple trips before hand and I think I gained at least as much as I gained with the cams when we did the big bore setup. I'm hoping to get it setup to dyno sometime next week.

I am trying to get some dyno time next week but it sounds like it may be a few weeks until we can work our schedules out to meet up. I'll post the numbers when we get done. You may want to consider the heads also. That made a big difference.
First ride on the 103 build today.....
