S&S Cycle 136" Crate Motor

[Ohio HD]

S&S has an M8 crate motor, a 136" complete ready to roll in all blacked out. Just guessing by the dyno sheet they're probably a little conservative with the compression. That has been their typical MO with crate motors in the past. But it still looks good. I also see they have the oil feed, return and vent in the case.

But I've seen our resident tuning guru rigidthumper do a little better than that with his 131" lower compression big bore M8.

That's the 49 state version with cat exhaust (i try to avoid those limitations )

Really now...

Wish they had one for the M8 Softail.

You can buy the components and use them in your cases...

Defeats the purpose of a crate motor.  I could buy Scramin Eagle stuff too, LOL

My biggest problems with crate motors.  In the end.  You have a crate motor.  Now offering unassimilable and a couple things off the list like pistons and cams.  Now we are building performance.

That's a misprint. The actual price is $11,999.99.

I can tell you what a high performance motor cost to build from the ground up, all new parts, high performance head work on brand new heads, new cases, etc. I easily will have $11k in it when I add it all up. And I mean every part, nut, bolt, etc. is new. That's with getting discounted prices on many parts.

Yup.  Try buying a crate motor for a hot rod car, anywhere from 20 -40 K depending on carb'd or turbo. I remember when Racing Head Service in Tn.  sold crate motors for under 4K.

My personal take-away is; they're mechanical devices built by man, they'll eventually break but when built right as most crates are, they're incredibly reliable and work extremely well. Add S&S quality to the mix and you should be good!

Only issue might be a snot-nosed Dealer with hurt feelings refusing to do service on a non-HD built engine if it ever comes to that.

Anyone know if this has a proprietary cylinder stud pattern?

My 2020 CVO Road Glide currently has 166,000 miles. I'd love to refresh it with a crate motor but that price is absurd. I wish they'd come out with something for folks who log miles and not dyno sheet number chasers.

For a little less money ($9999.66) you could always send your engine to Kernersville.

  I'd venture he takes way more care than an assembly line.

Scott, I get the impression (sometimes that takes a hammer) your application is long cruise or touring-type miles. Not necessarily hot performance.
If true, you could simply go with HD's replacement motor program (still running I presume?).We have done it twice now and really, it's a pretty good deal, if that's your goal. Another plus is HD dealers along the trail won't be snotty since it's still an HD product.
Just a thought.

I appreciate the feedback. I did not know about that program. The OEM motor has been fantastic and would have no problem putting another HD 117" in the bike. I'll look further into it

Yeah, gonna have to run that one by the wife. Pretty sure I know how that turns out! She's still bringing up the fact that I spent $5k on a perfectly good running motor. In 2005.

Trask just put one in a bike the high output motor, 147 hp 157 tq.

$12k for a 150hp engine? I get all new components, seems like a hard sell to someone that already has a complete and running M8. Not hard or expensive to get to 150h with an oem engine. I would love to see the business plan that produced an IRAD approval for this engine.

Believe me, turbo, I hear ya clear as day but guys are buying new HD's in my neck of the woods for $60plus Grand just to complement their new Dodge Hemi Ram!! What's another $12K for bragging rights for these guys - and let's not kid ourselves, there are more "plug & play, look't meee" types out there now than when we were kings. IMHO.
