S&S 625 cams & heads
#11
I hope the build meets your exectations and, if it does, that's what counts. I don't doubt the mechanical ability of the guy turning the wrenches. But what concerned me was the target of 100/100 peak numbers and 80TQ at 2500 rpms. You just don't need long duration, hilift cams and a potentially noisy valve train to achieve that goal with 103". Please let us know how it works out.

Dyno run
So here it is!
The bike runs smoothly, winds up faster and feels more responsive in every gear and accelerated 135mph very quickly and I was still in 5th and was still going strong but I ran out of road!
I know some will bang about the TQ not being high enough but seriously this is a great build. This thing pulls like a train and just keep on going!
My only minor issue is a decal pop when cutting the throttle suddenly at high revs but in normal riding it isn't an issue.

Update
UPDATE: Love this bike! Absolutely hammers! The mid-range is unbelievably strong, seems to be getting better with some more kms on the clock. Roars through the gears, hits the rev limiter hard, felt the front lift off the road flicking between 3rd & 4th today going so hard, scared the crap out of me!
Yes I do like speed and if you dont approve then dont bother commenting!
Next mod is new front brakes!!

STD numbers are meaningless for comparison, and usually result in the tuner looking good. That said, it does appear to be a solid tune... good power (relatively) under the curve, and the jaggedness is gone, indicating that it's not on the ragged edge of knocking due to too much advance or being too lean. Where's the AFR?

Its funny I happened to glance at the speedo yesterday as I was accelerating hard and the needle was moving so fast it looked like a tacho!

Yes, air/fuel ratio. A straight line AFR doesn't just happen. Having that data would let you know the time and effort that the tuner put into the job. It's obviously not too lean, but it might be too rich in part of the RPM range... meaning you'de be wasting fuel and leaving power "on the table." At WOT, you want to see close to a straight line in the low 13.x:1 range.

Glad you're happy with your build.... even if I am late to the party!!
Enjoy your upcoming riding season!
