Wood 777 cams are .575 lift. Still use stock head set up. All those cam numbers mean important things. But in reality, don't worry about them. Figure out what your ridin style is and match the cam description to that. Let the engineers worry about the numbers. Look at my set up below. This bike hauls! Period!
Great pull from take off past 5k rpm. I'm at 101hp and 111 lb. ft. of torque. I ride two up and we travel a lot.
Cam kit was $750 and included Wood 777 cams, Knight Prowler lifters, adjustable push rods, inner cam bearings, all the gaskets needed. I bought a Power Vision tuner and Fuel Moto got me a great tune. This bike just runs and again, it pulls great. The 2-1 exhaust was a great change and really help get more out of the set up.
Don't worry about all the numbers. It gets too overwhelming and really, just narrow down what you want out of your mod for your riding style. Fuel Moto is run by great guys who will spend all day on the phone with till you understand what's going on. Call Fuel Moto and talk to Bob. They are tremendous at getting you what you want and they will be there for any questions during and after the mod. Maybe the 222 or 555 cams are the ticket. Make some calls and talk to the people who know what the numbers mean and go where you feel comfortable. That's very important.
If you can change oil you can install cams. Just my opinion, but it's not hard. Fuel Moto has, I believe, 11 videos on You Tube that take you through the steps to change cams. S&S also has a good video.
