All Hydraulic and otherwise tension sprung H-d Products ( as well as their overpriced and JUNK "SCREAMIN EAGLE" UNITS ALONG WITH THIER cam plate and Cam configurations are JUNK !!!! BUY A GEAR DRIVEN S&S CAM SET as well as their Cam plate Unit and superior Oil pump for REAL performance and reliability upgrade .

 

Andrews 21N in my 01 Springer---- I might could be happier, but I don't know how.

 

I would disagree. I am running the Andrews 48 in my 05 Fatboy and love it. The bike pulls like a train for only a cam change and tune.

 

Thanks for that input.........

I have heard of the A48 being an excellent choice for a 103ci and even read a few good reviews of it in a 96ci... this is the first I've heard/read a report of them doing real well in an 88ci.... I guess I always thought of the 88ci being the domain of the A21... Even the A26, while many are happy with it in an 88ci, seems to do better in a 95/96ci, and with a little bump in compression....

Since this is the first report I've read of the 48 doing well in an 88ci, can you elaborate a little...? Is it stock compression & heads? Carb (CV40?) or EFI? Does it pull throughout the rpm band, or just low and taper off... if so, approximate RPMS...?

I'll have to put your info in the old memory bank....

I'm doing an 88ci cam chest upgrade in the near future, run out permitting, I decided on gear drive A21s.... Always willing to learn/explore new options..

 

I too did HD 203's in my '04 Fatty and didn't think much of them. In hindsight - 20 / 20 - I'd do HD 204's or Andrews 37's. as both work well
with stock valve springs. Power Commander III's are a good inexpensive tuner and lots of maps available. Imo.

 

2005 was the first year you could use the A48 with the stock valve springs. It was the year when Harley switched to the B-Hive springs. besides the typical stage 1 hi flow air filter and V&H longshots, the bike was stock when I replaced the cam chest stuff at 14k miles. I picked this cam because I really wanted as much low end torque as I could get with only a cam change. I used the Screaming eagle cam chest upgrade along with Screaming eagle pushrods and V-Thunder lifters. I also replaced all the cam bearings. I bought a Dynajet PC3 Usb tuner from Fuelmoto and had them pre-map it

The bike pulls all the way to the rev limiter setting at 5500

I have a friend who just did the A21 cam in his 2003 Heritage and I can pull past him with no issues

The exhaust sound after this cam was installed is awesome
