Default New 107 build just back from the dyno

Just got it back from the dyno what do you guys think? Pretty normal numbers? I think it's a little short on hp#s but it runs strong. Only have one little oil leak on my rear rocker boxes but other than that everything seems good. Forgot my dyno sheet at the shop. I'll add it later.

103hp & 116tq

2012 Flhtk
107 10.25:1
Kuryakyn 24d cams
Johnson direct shot lifters
comp cams push rods
street port on the heads stock size valves
V&H power duals with competition mufflers
K&N filter

Power Duals are holding you back a bit.

I agree, probably the power duals making it down just a little. Not bad numbers though and every dyno reads differently. Plus you don't ride a dyno, if it feels good, then it's definitely good!

From their website:

"The Crusher TC-24D Cams are designed to give you great torque and pull hard throughout the RPM range. Low noise and long valve train life are a few of the highlights of the TC-24D Cams. If you want an awesome overall power gain without beating up the valve train in your bike, these cams are for you. These cams combined with the Crusher exhaust and Crusher high flow intake system make a killer combination. Adjustable pushrods are required, but no head work, valve springs or piston clearancing is necessary. On our 2012 Street Glide with a 103 we were getting consistent numbers of 104 hp & 112 ft. lb of torque when combined with the Crusher exhaust, Crusher A/C and TTS tuning system."

Like already said, if it rides and feels good, then that's all that matters, unless you want to start chasing numbers on a dyno.

Ride safe!

Torque is what you feel when you twist the throttle. I’d say you have a good peak number. Where on the rpm range that torque comes on, peaks and how far out it lasts will effect how much a rider likes the feel of it. I like the torque to come on early and I’m fine with it dropping off considerable after 5000 rpm. I ride a touring bike, not a racing bike.
Bottom line is, if your happy with the feel of riding your new build, that’s all that matters. Enjoy!

Yep ... If you dwell on the numbers you'll be chasing better numbers for ever ...

Those are good numbers for a 107.
I love Power Duals.
Get the oil leak fixed.
If you like the way it pulls, that's what counts.
Ride that thing.

Those that said power duals are holding him back. Do you really mean power duals...or are you thinking “true duals”?

That's what I was thinking too. The power chamber design is to make power, you know.
Against 2 into one, sure, but I am diggin' my Power Duals.
