cam only swap is pretty straight forward, bolt in power
after that I would do gearing changes

 

When you do the big bore it really only helps if you also increase compression. If you increase compression the 48 becomes inadequate and the cams have to be replaced again to see much gain. If you plan to do the big bore in the future and just don't have the money for it yet I'd suggest the 57 cam unless you want to eat the around $200 for swapping the cam and selling the used one.

 

I've got two dynas, both TC-96's. One is a 2012 Superglide stage 1 with FP3. 20,000 miles on it. The other is a 2007 Street Bob, stage 1 plus Andrews 48's, 030 head gaskets, and professional dyno tune with TTS. 70,000 miles on that bike.

Even with the 70K miles, the 2007 with the 48's and pro dyno tune stomps the hell out of the stage 1 2012. Flat out runs away from it. Night and day difference. I originally thought I'd go to big bore, but no need for it as far as I'm concerned.

I just used the 030 head gaskets to bump the compression slightly and improve the squish characteristics. Another bonus of that is Andrew's 48's with 030 head gaskets allows you to run the stock pushrods. That was according to Andrews tech support. Some people don't mind adjustable push rods, but I prefer solid one piece push rods.

I can't stress the importance of a pro dyno tune enough. I had started with the recommended TTS map and then auto tuned it myself. I thought it was running pretty well and felt a little foolish spending the money for a pro tune. Wow, was I wrong. There was a huge difference in performance after the pro dyno tuned it. Huge difference. I've put 45,000 miles on it since the tune, and it still runs great.

Good luck with whatever you do.

 

I think cams are the best bang for your buck. I had an 01 Low Rider with 88CI and basic stage 1. It didn't have a lot of power. I put S&S 510G cams in it and a 2 into 1 exhaust and that little motor came alive. Night and day difference in power.

 

I have an 05 Super Glide. Was thinking about getting the Big Sucker. Does that interfere with legroom for reaching your rear brake control? Someone else on another thread has something similar to the Big Sucker, but he says it gets in the way of reaching his brake foot pedal.

 

The intake on my FXDL is an Arlen Ness installed by the PO. Not positive if it's the Big Sucker. If that's what it is (perhaps sig pic will tell), it does not impede brake pedal access for me at all (forward controls) and it not uncomfortable at all.

 

Bigger top end. .

.. careful. This is a deep pool.

 

Robert, you're discovering that Harley is similar to Jeep. Most owners mod them as their budget allows. Enjoy tinkering.
