All torn down!

All back together!

I am asking them to clean up a big low RPM dip in the torque curve with a little more tuning on the dyno, but right now I'm at 132.04 TQ @ 3,970 RPM / 125.58 HP @ 6,110 RPM SAE corrected.
I will post a sheet when/if it gets cleaned up.

Pretty stoked about the build to be honest...

Dyno Sheet 03.03.2022

[Mr. Warlock]

Can we get a better picture of that dyno sheet please?

[Justice]

This is the best I can do with what they sent me.

   Looks to me that a whole lot has changed on your bike not just a motor build!!  Very nice outcome on the build  what exhaust system are you running now?

The pipe on the bike is a Bassani 1S42RB Exhaust

I got the last one they had, and the pipe has been discontinued because the interest in these has fallen off since the M8 has taken over.

I also have a Thunderheader 1067B incoming for a backup map and tune, as they are telling me there is no way to tune out the torque dip in the dyno chart,
as it is a result of the cam/pipe combo, and I do believe that I will feel that dead spot at 2500 rpm regardless of throttle position.

I am selling my RB Racing pipe that I had on the bike when I dropped it off with them.

Looking for some feedback from the builders & tuners on this site, on whether you think it is possible to tune out this low RPM torque & HP dip in this WOT pull, and how you think this dip will translate to other throttle positions (20%-60%).

#1 - Is what I believe the bike ought to be able to be tuned to based on similar builds and dyno sheets I can find
#2 - Is what I was after with my build, and would still like to achieve by changing the pipe if necessary

I have a Softail with the B motor, so I cannot expect the same results that Dynas and Touring bikes can achieve.
I do have a Thunderheader headed to the shop at this time, and the RB Racing LSR 2-1 Slash Cut (baffled) pipe was never used (because the dealer thought that it was a straight pipe and would be impossible to tune). I am not sure what the best pipe is for a Softail B Motor for torque/HP.

Any help would be wonderful. Thanks!

Well Folks,

I couldn't live with the torque dip from the Bassani RR 2-1, so I had YHD install a black Thunderheader today and retune the bike...
We got the right pipe on the bike now!

125.04 HP @ 5500 RPM / 134.99 TQ @ 3940 RPM
No Torque dip, AND I get the Thunderheader sound I have loved for many, many years as icing on the cake!

Don helped me pre-build to get everything figured out, and suffered my lack of knowledge like a true gentleman.
Sent me pics along the way to show me what was being done, worked directly with YHD to facilitate the work and shipping, and also provided flow charts to YHD with my parts. Well done Sir. I’m glad I brought you into the project. Thank you!

Great looking bike and build results. It has to be an absolute blast to ride, congratulations!
