Howie,
While I am a motor illeterate, it sounds like they designing something that has solved ( in theory) many complaints about current v-twins, allowed them to comply with current epa restrictions and still produce high output motors ( also may push MOCO into development of new frame unless the Revolution engine is their savior of the future!). I guess once in production reliability and longevity with tell the tale. (kind of reminds of car industry where in 70 and 80's had these epa choked engine that through redesign now have met epa restrictions but get good gas mileage and have performane enhanced numbers.)  Good article, john

John, that's exactly what I see them doing. And if HD ain't doing the same thing, they'll either be buying motors from S&S or using the Water-Cooled approach, in the near future. I hope they're doing the former! Hoist!

Read the test ride article in the latest cycle world .. looks like they still have some work to do . but it is promising.

S&S thinks it's their future! Here's a link to the S&S X-Wedge Home Page. Lots more stuff, photo gallery and sound bytes there! http://www.x-wedge.com/index.htm  Hoist!

Pretty Cool.  I would take this over the revolution water cooled!

I am not a mechanical genius like some of y'all, so what do you think of the belt driven cam setup?

Well, I'm not a big fan of belt driven cams, but they have been doing it for years in cars, and the above article says that if the belt did break, the valves wouldn't hit, you'd just be stranded. Less resistance that the current setups to TC.

The Crank Position Sensor (CPS) reads off the side of the flywheel. Removing the case gives you a good look at the massive crank assembly…

This flywheel scraper oil return looks a very much like the design used in my ‘46 Knuckle to evacuate crankcase oil. Big Twin’s, K’s and XL models used this method for decades to transfer crankcase oil over to the gearcase for pickup and return to the oil reservoir. This method was dropped in 1977 on XL’s and with the advent of the Twin Cam Big Twin’s.

I am somewhat surprised to see S&S choose to stay with this dated, “old school” design. IMHO, the mini sump with direct oil pickup is a far superior method of handling returning engine oil. For what it’s worth, I see that Indian’s proprietary V-Twin engine uses the same early H-D design as well.

I can’t help but wonder if this old method continues to be used simply because it is available.

Thanks for the great presentation, Hoist; good stuff!

Hoist are you a distributor yet?

Howie,
I think AJ hit it,
We will be your first customers!!!
