When the numbers fall short, everyone says they were only after "silence and reliability." ::)  Glad you're happy, though! :2vrolijk_21:

Fall short of what?  We looked at a similar build from a year or so ago and they were right there.  These numbers are exactly what we expected.

OK, I couldn't wait.  109/113.  No, it's not a balls-out build.  With a Fatcat I think I would have seen the torque around 120....But then I wouldn't be able to ride it for more than 20 minutes.

We ended up with 12 discs and open caps.  That makes for a deeper sound that's a bit louder than the closed caps, but not obnoxiously so.  It's still quieter than the 255 with 15 discs and the closed caps.

It doesn't feel fast.  It's not an arm-stretcher.  The lower cylinder pressure makes for less immediacy when I jump on the throttle.  There's more power, but it spools up a bit slower.  There's also a TON less engine braking for the same reason.

Other than the intake noise (which I really hope I get used to) it's a great touring build. And it highlights the importance of having a builder who asks the right questions and listens to the answer(s).  I did not want a beast of a motor.  If I did, I would have gone with a 10.5:1 113 with a different cam (T-Man 625 probably) and headwork.  I would have been well over 120/120 with a different pair of mufflers.  But that's not what this build was about.

With a CCP around 192, I've got a build that won't beat the hell out of the crank (I was 215 stock), and isn't loud.  I've got plenty of passing power, and great roll-on response.

BTW, the initial peak torque number was higher (with the closed caps) but the curve looks a ton better now, doesn't it?  Bragging rights don't mean squat when you're going down the road.

Dave did it again.....He built the motor I wanted, not the one that makes for the dyno chart that'll sell a ton of builds.
