I got a call from Jim. He’s got my scooter pretty much done including dyno tune. He was very happy with the motor. He says it is much quieter. He also said she’s “a torque monster”. However, he was disappointed in the final horsepower numbers. See attached sheet. I can’t wait to see how she runs. 120 ft lb from just shy of 2500 to 4600 rpm should be exciting. She drops from there but that’s a lot of power in the range I ride the most! Good for a bagger.
Jim did a great job keeping me informed all along the way, sending pics and a video as well as answering a lot of questions.

I told Jim this motor has historically made good torque with below average horsepower. I can’t wait to ride her to see how she feels. However, Jim and I did talk at length on what may be causing the low horsepower numbers. Jim said there’s an air flow issue with this build. He talked about the pipes, throttle body, and/or the heads not flowing enough for this build. I went all the mods I have done with this motor.
I had the D&D Fat Cats w/ Quiet baffles on this build before. However I really like two pipes on a bagger and was not interested in a falsie. I talked with Greg (04SE103) about the BUB 7 True Duals. Based on his results I decided to give them a try. A dyno was done comparing the D&D F C with the BUB 7 T D. The BUB 7 T D had the torque come on earlier. At around 4200 rpm the pipes were even on torque with the D&D F C carrying the torque out longer from that point but only by a couple of ft lbs. The D&D F C made 3 more horsepower but that was after 5000 rpm. Based on these results, I am happy with the BUB 7 T D. Love the look and the sound in comparison to the D&D F C. See
