Not much feedback on these cams yet, but the few dyno sheets I've seen posted on a couple of the other forums have looked very impressive. I'm deciding between these and the new Kury tc24d cams coming out soon.
The 57h is a higher lift version(.560" vs .510") of a 37H so it should perform the same while being able to hold a bit more power on the top end.
I've used the 37 in 95" motors in both my past bikes, WideGlide and Ultra Classic, and was very happy with it. Pulls very well through the gears all the way to 6000 rpm or so. In carb'd applications it can be a bit pipe sensitive, leaving a hole in the power at 60mph cruise speeds. I'm certain this could be tuned out with EFI. Was especially bad with an early V&H Pro Pipe.
I've got an SE204 in my bike now, primarily because it's basically a 37 advanced 4* which was something I always wanted to try when I was running the 37. It works just as theory says it should, more bottom end, but is all done by 5500rpm. The 204 works well with the 6 speed gear box.
So, put the 57 in, I suspect you'll be happy with it. If you find you want more bottom end the fix is as easy as putting in a 4* advance sprocket.
So today I ordered D&D Billet cat 2-1, S&S intake and a DynoJet Powervision tuner. For my 18 RGS
I'm not looking for big bore, but thinking about changing the Cam.
Looking at the S&S 475C, Tappets and Pushrods/tubes, I dont see any reason to go gear drive unless someone has so e info?
I've done some searching on the site and couldn't find any post about this. Looked on HD forums and saw that people were complaining about excessive valvetrain noise. They were saying that the stealerships were telling them it was normal. I recently got back from the Dragon which I rode every...
Hey there, I am finding that is getting more and more difficult to get the bike in neutral when stopped at a light or sign with the engine running. As soon as the engine is off, no problem, pops right in.
What would be causing this?
2017 RGU - Stage 4
I have a 2017 Road Glide Special. It has spark knock under hard acceleration. I know it's not the fuel because my buddy has a 2017 Road King and his bike doesn't do it (we went to the same gas stations, same gas on a trip). I took it to the dealer, and they confirmed the spark knock. They are...
