Little update:
This week the motor is getting torn out and cases sent to Darkhorse.
Heads are done now just waiting on the mock-up bike to come in for the custom exhaust.
We switched over to a Bandit clutch, mostly due to Wolfgangs recommendation as well as a few others on here.

All I know is that it will help pull weight out. Our goal is to pull some weight out without adding excessive vibration.

Sounds reasonable enough. That's going to be a nice motor. I put a darkhorse man o war crank in my bike back in September last riding season and it really made the bike so smooth. Higher the rpms the smoother it gets. Just sucks something so nice looking is hidden inside of the motor lol.

From my understanding, its a combination of diameter and length. So the diameter keeps the exhaust velocity up (depending on motor size) while the step length is set up at the right spot to "pull" the gases out of the cylinder at certain rpm.
On my pipe, the step lengths will be dialed in for mid-upper power where the cam comes alive.

Since our little discussion about crankcase breathing, I decided a ventilator cap from A1 Cycles when they get back in stock.
The head porter is very happy with the exhaust flow numbers on the heads, he's still searching for more out of the intake port. They will be done very soon, as he stated that when a set of heads go on the flow bench they are his main focus until he is happy with the numbers. Before when he said they were complete he was taking about the bigger valves and most of the port work, he's still tweaking the seats to get them where he wants.
Got the bearings pulled in the Deuce rear wheel, going to throw it on a mill soon and drill out the center for a ř1.25" OD tube for the 1"axle. Stuff is slowly coming together finally.

Nice to see guys are still out there, building, tweaking, and setting up big HP street driven V Twins to try and go fast!
Not simply buying a bike and adding a cam or pipe whatever-best of luck how it all turns out...

Back when you ran that badass 131" was that a race gas only build or were you able to run pump if you wanted to?
