Default Big bore or cam?

2007 RK Custom. Screaming eagle air cleaner. Stage 1 download. Rush slips ons. 9000 miles.

I would like a little bump in power. I am looking for reliability and longevity. What should I go with?

Add better cams to my 96?

Install a Screaming eagle 103 big bore?

Add a V&H 2 into 1 pro pipe with tune?

What would give me the most power?

Thanks
Sam

I like the Big Bore kit to start. Then build from there if you want to.

Some good arguments for doing the cam vs. big bore here: https://www.hdforums.com/forum/softail-models/603715-to-big-bore-or-not.html

I know you have a 96ci motor but I wanted to show you what Jamie at FuelMoto did with just a cam change. He's working a new Woods cam into an 88ci motor and his 88 is making more power than a stock 103: https://www.hdforums.com/forum/touri...e-testing.html

Heard a lot of good things about the FM 107 kit. My dealer even says good things about them. Just for an example my dealer is doing a 103 kit complete with true duals for $3100. 110+ hp and 115tq. He says its more reliable than new. I have a friend with this build and it runs like a scalded ape and the motor is as quiet as a stocker. They travel on it constantly and have no problems.

Well a big bore kit without cams is limited to stock cams. I'd go with cams first. Then if not enough add the big bore kit. There are some quick cammed 96 bikes out there. My two cents...

On my 09 RK
I am going to bump up to the 103, cams, roller rockers and Vance Hines Propipe Hi output. I aready have the Sert.

And the the clutch.

With proper cams and pipe 103 is ample.
