    Awesome build. Be nice to see how much difference octane changes output. Like shell power 93 vs Marathon 94 vs Sunoco 92. I'm always hunting for ethanol free myself. Consistent fuel is key for consistent tune. I can tell a difference in the way the vrod runs different on power compared to Sunoco premium. Sunoco seems to run better

    Nice build and great results.. About to do the same with mine, 2020 FB 114 to 128. Looks like you kept the OEM cam plate and oil pump, is that right? If so how is it doing.? One of the things im on the fence to replace because its running just fine with stage 2.

    • @robb907
      @robb907  10 месяцев назад +1

      Thanks I appreciate that. Everything I have learned is that you don’t need to update past 2020 because the sumping issue has been corrected with the third gen HD pump however, I went with the S & S oil pump for my newest 131 build on my ‘22 road glide ST. Probably not necessary, but regardless just make sure that you use the seal from the stock pump or buy a brand new one for 10 bucks because without that seal, you will have problems transferring too much oil through the pinion, bearing into the crank case. if you want more info on that then i have a video I did when I installed the seal that my mechanic forgot to put for the build I did on the road glide. Basically, the $10 seal is more important than the $800 upgraded oil pump.
      This is the video about the seal:

    I’ve seen seen several reports that the stock heads flow pretty darn good as is. Real easy to screw them up. Have you done any dyno runs comparing the ported to stock or the HD big valve heads? I’m thinking about the best way to go.

    • @robb907
      @robb907  2 года назад +6

      Yes that is true, but they can’t handle more than .475 lift cams. If you want to go with a beefier for your cam then you need to change the valve springs at minimum. If you look at Fuel Motos website you can find dyno charts with just about every combination of cam and head along with different size bores. I chose to skip over stage three and go straight to stage four. I think the difference is probably 15 hp and maybe 15 foot pounds torque better with CNC ported and polished head and with lift valve springs. I hope that helps.

      But I'm glad to see I was wrong about the dip.
      I suspect your Hpi gave the mail-in tunner the ability to tweek the air/fuel erasing the dip.
      I run a TRASK Shorty on my Fat Boy, and I have that dip. My bike doesn't like hold 35mph...that's the dip.
      I got a SE 64mm with 5.5 injectors.
      OBTW, you were right the first time, the smoothness in your DYNO line compared to your buddy is the more favorable over any gains of 1-3 Hp and/or Tq at those levels.
      The only other thing one would desire is a flatter line.
      I hope my line is as smooth as yours.

      @@SQUID_Road_Glide I think Trask makes really nice products. Will be interesting to see how yours turns out with the Jackpot exhaust. Keep me posted.
      I’ve learned a lot about these big bores since this build. I have a 160 hp 131 RGST now. It had the same dip. Our dealer here doesn’t have a trained tuner but he does a good job. All he does is run the Power Vision Autotune feature on the dyno. On this Lowrider I called Fuel Moto and talked to them about it and emailed the map back and forth. But now Billy has learned enough that he talks to them directly while the bike is on the dyno and sends them data logging. Then he makes changes with their guidance.
      Fuel Moto told me that the dip is partially caused by a short pipe, but also the Power Vision autotune for some reason. Either or can be manually tuned out though. My buddy’s map is tuned with the Harley tuner, which is also an autotune process on the dyno, but I think he can connect with Harley for any issues. But notice how good it did for a Harley product with no dip.
      My Road Glide was a little trickier to tune because it had us a lot of nice goodies on it. But Billy made it run really nice.

    • @robb907
      @robb907  Год назад

      Originally I was going to go with a stage III 10.75:1 low compression build. Then I decided to go with stage IV 11.5:1. So the math works out to shave new heads versus higher compression pistons. You end up with the same result. The heads were already CNC ported and polished with behind valve springs, so all they had to do is shave them, and ship them.

      Yes, huge difference for sure. Stock was 79hp/105tq (approx)
      475 was 115hp/123tq
      Big bore 128 and 408 cam 141hp/150tq
      For your consideration - I ran the 475 cam for one year and had a super bad ass fun time on it. I put 3200 miles on it so I reused my S&S lifters, push rods etc. so the net loss of cost was the cost of the 475 Cam only, $200 ish. So if overall cost to do the big bore build was going to hold somebody up then they could still enjoy a stage to build, which is a ton more fun than stock. Plus it’s kind of fun to do in stages. I’ve been riding this bike around for a week now and it is ridiculously quick. Still a little too cold and the streets have a lot of sand on them still. But I can tell you It pulls right off the line and keeps going.
      I hope this helps… 🤘🏼
