Harley has just announced their 'new' single cam engine for touring models, with the added bonus of 4-valves per cylinder. Deep joy - we were right all along - single cams rule!

 

I am loving every second of it!!!!!!!!!!!!!

 

It is a curious thing, why they went back to a single cam. Hard to understand that one.

Oh well.

IMHO, the Evo remains the last authentic HD engine. Everything since is an EPA mandated hack trying to simulate what an HD engine is supposed to be.

 

^^ The EPA had it's fingers in the EVO as well...
Hell.... they are who Ruined the Shovel...Doomed because it couldn't pass EPA "standards"
4 valve heads May improve efficiency to the point that the poor thing won't take a performance "Hit"..

 

So twin cam people can't buy new heads and rocker assemblies and get the "new" 4 valve motor. Not because a single cam is superior. All four of those push rods pointing at one cam is exactly what Harley said was one of the things wrong with the Evo. Now it's "reduced parasitic losses".

Up next; HD bell bottoms

 

The new engine idles at 850 rpm. Peak torque occurs at a lower rpm than it does with a twin cam. In other words, it is looking like the Milwaukee 8 is more of the successor to the Evo than the TC was.



Stock normal Milwaukee 8 is 107". They sell a bolt on kit for $1,995 that increases displacement to 114" and provides a 39% increase in power over stock while remaining 50 state legal and EPA compliant. It increases compression to 11:1 whooohoooo

Winner winner chicken dinner!

 

2k for 7 Cubes????
I would take my chances...Done it before...
Think about it... Who knows what the limits of an 883 are???
Not many...But some do.

 

I think the main deal is increasing displacement by only 7 cubic inches but increasing power by 39%. That is pretty awesome.

On any other engine, how much money would it take to reliably increase power by 39%, let alone being able to do it while remaining 50 state EPA compliant.

No case boring required either. Just a bolt on kit.

 

^^ Like I said...How much Power is Hiding in an 883???

 

Anybody remember Rivera 4 valve heads for the Evo? Life is just one big circle. LOL!
