Icarus After Dyno

So after my 2 hour dyno session with Mark, I made some headway and learned some valuable info on Icarus. The bike limped along at about 25 hp and 40 ft pounds when I got it there, but keep in mind I had just made a new exhaust and had new carb needles in. After a baseline run we determined that it was way rich from about 3000 up. A few adjustments in the carbs and we were doing better. We also advanced the timing about 5 degrees and it really woke up. By the end it was making 42 hp and over 60 ft pounds! I know a lot of bench racers will give me shit for not making more power, but the reality of v twins is often quite different from what is written in the catalogs. I challenge anyone to build their own motor from scratch and make more power than that (at the rear wheel) with 7 to 1 compression! I already have plans for phase 3. I am shooting for around 65 hp and 80 ft pounds without raising compression or cam lift. I also spent an entire day riding around new haven on her and she took it like a champ... good little bike.
