lets talk cams
Im sure this topic has been beat to death, and i did a search before posting. Could not find the excact answer i was looking for.
What size cams should i go with if i wanted to gain 10-15 hp's and some more low end torque, as i do a lot of 2 up riding. Are the S.E. 203's the ones to go with or is something like the 255's or 260's better. Will these cams work with a stage 2 big bore 103" that i would like to do in the future.
Currently i have a 96" tc motor w/ stage 1 a/c cleaner (i am in the process of getting a big air sucker) also have SERT w/ V&H big shots dyno'd at 75hp with 85lb torque.
Is 10-15 hp's a realistic number to be able to get out of cams?

2012 WG and I'm pretty much decided on the S&S 551 cam.
They tell me more torque right off idle to about 4500 rpm, more for actual riding than drag racing and that's what I'm looking for.
A previous poster here said the 254E was his prescription

I am at the same delema, looking at the 555 woods cams from fuel moto. Like to have low end torque. I am doing the install my self so I am looking to buy some tools to help remove and install the rear bearings. Looks easy to do, did lots of research. The only thing that makes me a bit nervous is pulling apart a 4000mile good motor.
Fuel moto has good service and they will up grade my power vision so I will be looking at the woods cams.

I think an S&S 551 or SE255 looks like a great cam for lots of 2-up riding. I rarely ride 2-up, ride a lighter-than-a-dresser bike, and want an increase in torque in the 2000-4000 rpm range.

I'm guessing here but I would have to say - unrealistic , on my96 tc engine
with 103 kit stage two with hd 255 cams I'm getting maybe that kind of numbers. I don't know because I use a powervision and she kicks plenty without a dyno tune.

You aren't gonna get there with just cams. My bike has 107hp/115tq see sig for mods.
Your gonna have to add cubes. That being said the 555s are a great cam and will increase power across the entire powerband. The 255s will give you stump pulling torque and will be a blast from light to light,and roll on power will be significantly increased.

Get a note book and digital camera, then each step, no matter how minor, take a picture or two and jot down what you did.
Label parts as they come out and which way they go in. (bevel in/out etc)
Also make sure you have the shop manual, you'll need torque specs and such.
I use this method on lots of things I work on, fishing reels, tranny's, motors, whatever.
Might help ya.
