I picked up the "Silent Gray Fellow" today. They got everything installed and did a "gentle" dyno on it just to set the AFR at 13.6 and give it a nice smooth torque curve and good pull. All I added performance-wise was the Klock Werks Revolver mufflers and it dyno'd out to 87hp/105 Tq, up from the stock baseline of 81hp/100Tq. So not too shabby for just adding mufflers. I really like the sound of the Werks pipes. They have a nice mellow rumble to the, but are not loud. They quiet down nicely at cruise, but will "bark" if you want them too. I didn't get to ride it much today, only put on 50 some miles, but will be putting it through it's paces tomorrow and, hopefully, Monday. Initial impression, this thing is freakin awesome!! Without a doubt, the most comfortable seat I've ever sat in that was made by the MoCo. Not sure about the windshield, I may have to go with a bit taller, or same size with a re-curve. Jury's still out on that one. Sound system is with the new Boom Audio speakers is sweet. Very clean sounding at 70mph. Can't wait to take it out and get some more time in the saddle, this bike is sweet, and the color rocks out in the sun.
