Yes, the ported heads came pre-installed with appropriate springs.

Thanks Beartooth.

I just picked up the bike. I did a 10 mile test ride, warmed it up good, did some low and variable speeds, then laid into it. Only broke 100 mph 5 times

. Hopefully that is out of my system now and I can just enjoy the power during more relaxed riding, passing trucks, etc.
It runs smoothly at all speeds and throttle openings. It comes on hard and I think it will keep me happy. No more performance mods needed. That might be the first time that phrase ever came out of my mouth!
Piper Performance did a really nice job with the tune. I would highly recommend them. Shop is organized, very well equipped, and neat as a pin. Cliff took an entire day on the tune, and it shows.

The extra power is nice riding in a group in passing situations on two lane roads, when the rider in front of you considers it safe to pass, you can have confidence in your performance to go with him.

Didn't you start out with the Power Vision on this build before you found Cliff at Piper Performance?

I'm reasonably familiar with what is available in PV, so when I picked up the bike, I had Cliff go through some of the things TTS had that were different or not in PV. One that stuck out is the setting for cam timing. Either way, I got some good use out of the PV and learned alot about it. I guess Ican add a license to it for another bike if I want to use it again. I know Fuel Moto tunes similar builds with PV, so I'm sure it is capable.

I get it, trust me once you start down that road, it's all in the pursuit of happiness.

Just a quick update on the FM124. I've now got 2300 miles on the kit and mileage continues to increase. My last 2 tanks were 38.7mpg and 40.2mpg. Although FM says it's broken in on the dyno, it appears to continue with the breakin process for a couple of thousand miles beyond that.
