Have a 2017 FLHXS, and I simply hate how it sounds. Can't trade or sell the bike, will lose my butt. So I am wondering if I can pull the M8 and install a Twin Cam like the 120" from HD or the 124" from S&S. Will the tranny line up, what about the engine mounts and wiring harness, computer?

 

It's not going to be a direct bolt-in swap. Gonna take quite a bit of re-engineering on you're part if you're capable of that sorta' thing. Fuel-Moto has a 120" M8 upgrade. Give them a call.

 

Agreed, I also responded in your other thread.

 

what?! get a twin cam bike. have someone take over the payment. or swap payment with someone. use all your resources. talk to your dealer for help getting out of the bike.

 

That's pretty damned extreme to get the right "sound"... Plus, no matter how much you lose selling the bike, it'll be less than replacing the motor and "engineering" a twin cam to fit.

Sell the bike, take the hit, buy a twincam.

 

My thinking as well.

I think I'd learn to live with the sound. But that's just me.

 

Change the exhaust system! Try to get a sound you like

 

Add compression, cam, good 2-1 exhaust, 117-120 big bore, throttle body, injectors. It will sound like a Harley and a lot cheaper than a motor swap.

 

this thread is over a year old now. back when it first popped up, there really weren't a lot of options available. Now there are many more options available to improve the sound and power. The one thing however IMO is that you can spend a bucket of money to SLIGHTLY improve things. to me the bang for the buck just really isn't there and probably never will be there. I am still on just slip ons and I am happy with that.

 

Change that to a 2-2 exhaust and it will sound better.
2-1 makes any engine sound crummy
