I have a 97 evo with a big sucker intake and samson fishtails with no baffles, stock motor. It is a lot quieter than my 2001 road king that has a built motor and straight fishtails.

I assume cam, heads, pistons would be what would make a difference on the evo? I had planned a cam upgrade.

Thanks guys

 

I am hoping you get some good answers. I picked up a 89 touring bike, all stock, and it is the quietest bike I have ever owned...

 

In my opinion the Evo is the nicest sounding engine but I like a smooth quieter sound.

The Shovel is just the coolest. Twin Cam whirs around making me wonder if that's right.

If you want a loud badass sound from an Evo you can go with some shitty drag pipes or Rineharts.

 

I have V&H long shots on my 94. Not quiet at all. Its compression that makes the noise. Stock FLH evo was lame. but that CR up to 10.5 to 1 and its a totally different sound / bike.

 

Thanks guys. I'm thinking when I do the cam upgrade, maybe do the higher compression wiseco pistons then as well.

 

Engine size plays into things too...the evo is 1340/80 inches....and the newer High Compression ones are 1500 and up....more fuel, more air....bigger bang! But pipe choice and tuning of the mufflers does help develop a particular sound.

 

Thanks.

If I get wiseco pistons, and leave my heads stock, is that just a regular bolt on install, no machining etc?

 

if they are comparable to stock, yes just put them in. If they are for higher compression ratio or different stroke then of course you need the mods that enable that fitment.

 

Definitely worth getting the cylinders honed to ensure a good seal for the rings. Torque plate hone is better. Simulates head bolt distortion of the jug. Usually no more than $150 for the work but your in for a gasket set as well. All very worth it imo.

 

Ok, so for example if I get the 10:1 wiseco pistons, some machining work has to be done as well?

Thanks
