Their kit is EPA legal, so would not expect big power.

I’d rather see the MoCo develop the Revolution engine into their lineup.  Air-cooled days are coming to an end...

Do you have the numbers and the dyno sheet?  Inquiring minds want to know.
Their standard crayon charts are on the website with the kits.

Buyer beware ,you have to surrender your existing motor cases back to HD,as they use your existing vin on the 131" !!
Makes no sense ( unless a trashed motor) just buy the top end kit on a new bike?

or is there something special about the 131 bottom end (timken) ?

I doubt it and I agree with your advice.
Better yet just buy the pistons and cylinders and have your heads ported by a competent shop.

According to a dealer in VA, there is a crate engine available for $6200.

Sounds like one of the VA dealers owned by Ken Barner. I'm actually thinking about it.

If I bought the crate motor what do you all think I could sell my current stage 4 from my 19 RG for?

. Like stated above, You have to turn in your cases to your stock motor so they can stamp the new crate motor with your vin numbers... I bet this will screw a lot of people for exactly what you are trying to ask about... Would be nice if they let you buy the crate motor plus keep your stock one, unfortunately they do not...

As stated earlier, this really isn’t a crate engine, it’s just a Stage 4 kit. I don’t believe you have to turn in your cases as this is just drop in cylinders and top end. I suppose they added a different head pipe as well, but nothing changes with your cases.

In addition to the Screamin’ Eagle 131 Crate engine, Screamin’ Eagle also offers 128/131 Stage IV performance kits for those riders looking to keep their stock crankcase. These high-performance kits slip into your factory crankcase without machining or removing the engine from the chassis. Screamin’ Eagle offers a full line-up of performance products to fit your riding style. See your local dealer for details.
