what would you recommend for almost 90 percent city use riding solo.
0-60 all the time quick , then cruising 40.
my top 3 is cyclorama 570-2 , woods 222 or 999 and ss 583
i ride between 200-3500 rpm 95 % of time
You are going to want a high torque, low-mid RPM cam, there are quite a few cams that would fit this application. I would consider the TW-222, CR-570-2, Andrews 48H, and S&S MR103 as our most popular choices. As noted several others from this test group would also work very well.

The CYCLERAMA 570-2 gets my vote. I have yet to see a better all-round dyno sheet..

George, I have been a fan of this cam, since you first started posting it’s dyno results from Sheffers. But now I question it’s validity, due to the findings of Fuel Moto. Not to mention the lack of variety by Sheffers. Fuel Moto sells all of these cams, so I have to believe they’re being impartial.

Don't forget....

FuelMoto put all cams in the same bike, same exhaust, etc., so the only variable between cam results would be the cam. This was done to provide a good apples to apples comparison between cams....

I'm no expert, but I believe certain cams may benefit more from a specific exhaust. I also have read that Daren prefers a specific air cleaner for max power... I forget which one..

I'm sure FuelMoto knows which cams work best with which exhaust/ air cleaner combos. I'm sure they can add cams, with other accessories that would yield better Dyno graphs than the ones used for comparison...

Then add in the different environment, different dyno, etc... and it's not unusual for bikes to get different dyno results.... with the same equipment or the same bike.. on a different dyno in another area of the country...

Doesn't mean anyone is playin games, just the nature of the beast...

Darren likes the Boyesen Power X intake, which is why I bought it. Lol

We performed this test to show the characteristics of each cam with same components in the same enviroment. Change any one of these elements and you lose relevance; change multiple elements and the value of the data heads towards irrelevant.

For sake of comparison take a look at the dyno chart below, this is a good representation of the relativity when comparing charts and different components. This is the same bike on the same dyno with the same 103" engine configuration and camshaft; the only difference is the exhaust system and it was a couple days apart. Again, change one or more elements and the results will change, it's just a question of how much and which direction.

I'm cam shopping myself and 2 of choices were confirmed here and by both vendors. One of them I mentioned in another thread and really got no response so I thought maybe I was missing something. That was concerning woods cams.
I was thinking the TW999-6A as opposed to the 555s. When I called Bobby this morning and asked what cam he recommended for my stock 2013 FLSTC stock stage 1 103 he was adamant about the TW999-6A.
My other choice was the S&S MR103. A call to them this morning and I got the same response. Definitely.

Good to see these confirmed here. Thanks for all the hard work! I'm still tossing these 2 back and forth. Any imput from anyone else that might help tip the scales?
Little things like valve train noise, easy on the valve train? Ease of tuning? Those kind of things?
I'm running Rush slip ons that perform very well with overlap/scavenging with no reversion issues anywhere.
Thanks.
