Cam Upgrade

I have a 2012 ultra classic. it has a stage 1 kit SE K&N ac and a decatted stock head pipe and Jackpot slipons. I had it Dyno'd and it runs good, but I am going to di cams this winter and the info is staggering. My tuner said he will do the install new lifter, adjustable push rods and Dyno OTD 1200.00. He syddesred S&S MR103 but said he didnt really care. The Dyno xharts look good but so does the Cyclerama 570-2 anyone have any experience with them? Thanks

General consensus is that the CR 570-2 performs just a click above the others.

Other good cams that will give similar numbers/feel: Andrews 48, TTS 100, Woods 222 (overpriced IMO), and that MR103 seems to perform well from the dyno charts I've see. I don't think you can go wrong with any of them. If i were to cam my 2015, it would be the 570-2 or the Andrews 48

CR570-2's or Andrews 48's would be the two I would be looking at...

From what I have read, I really like the 570-ll. finding much info and dyno on the MR103 has been tough. He claims to have installed them in a lot of bikes and everyone has loved them. He probably has good base maps and it makes dyno time quicker.

With that being said pick a cam that fits the majority of your riding style and your engine specs. I have S&S 551 cams which is perfect for 90% of my type of riding. Two up with all three bags loaded in the mountains. The downside is when I ride alone to work. I wish my engine had better acceleration and mid range which I believe the MR103, 570-2 and 48 would provide. Did your tuner ask about your style of riding?

Yes we talked about it for about 5 mins and future plans. We have a lot of mountains here in Wa. State. I ride 2200 to 4500. I am not looking to get the best Dyno sheet I want a bike is fun to ride in out twisty mountains.
