i had Fuel Moto's 107 installed in my 14 Ultra Classic. Performance increase is amazing. But lookin for a bigger bang. Currently running Woods 555 cams in the set up. i was told Andrews 57H cams are a real kick. Read the reviews and it looks like everyone who installed them and then wrote reviews on them loves them.
Is it difficult the replace the cam? I am not afraid to tackle anything. i did most of my own wrenching on my old '04 Yamaha road star.
I looked on you tube for 2014 HD cam replacement and found nothing.
I do have the tech / repair manual. and I will read it numerous times before I to the cam replacement, but I would like some tech info before I begin. Or would y'all recommend i simply take it my mechanic and let him do it?

 

Do it yourself. Not that difficult. FuelMoto themselves have cam R&Rs on youtube. Any Twincam youtube video will be relevant. I run 37s which has the same specs as the 57s just less lift. Love them. Nice powerband and a nice idle.

 

thank you. will I need anything else? like a new gasket? or anything else?

 

It's actually quite easy,

Here is a link to my cam install. In your case FM probably replaced your bearings and rods already. In fact, I just replaced my 57's and that part of the job probably took me less than an hour including opening the cam chest and all.

The only thing I would mention, is to look at other cams that might suit your riding profile. The 57's are great but I'm not sure that they offer much beyond what you already have. But do a bit of research and decide for yourself .

You don't want to push that 57 up past 10.0 cr.

I don't think you will notice much of a change at all. Maybe a little down low but that's about it.

IMHO,Not worth the swap out....

 

at 10cr it should be around 193psi ccp, fine, but doesn't some bluid work at around 200ccp ?

 

The OP didn't say if the heads had been worked or what head gasket was used. The only way a cam change increases performance is with more lift and the only way more lift increases performance is with heads that will flow at the higher lift. If heads will flow at the higher cam lifts, the 50mm throttle body becomes the potential bottleneck. So, back to the original question; have the heads been ported, larger valves, springs the will accommodate higher lift, etc. If not, heads is the place to start and a conversation with FM would be a good place to start that conversation. A change in trans pulley size will give better results than just changing cams.

There are several cam options with lifts of .600"-.660" that could help but you have to start with the heads and work backwards to the intake and match up the parts. Once that's done, get out your wallet, service manual, roll up your sleeves and let the wrenching begin.

BTW, has the 107" build been tuned? You also did not mention what exhaust you are running.

 

Not sure I see enough change to justify the cost and labor...

Sometimes people make lateral moves, this could be one of those times.
