H.d. Launches A New Engine


Recommended Posts

Yawnnnnn :nod:

 

Back to single cam 4 valve shower heads & no major drivetrain changes.

 

The EPA SPANkings finally got results.

 

goodbye Twinky :Off-Topic2[1]:

Interesting Thanks.

 

Brand X research shows these riders want a free shower and hot breakfast sausages during morning ride.

They've bumped the CID to 107". They showed the primary of a Screamin' Eagle with 114". The cubic inch war is alive and well.

There's the four valves per cylinder Ken mention in another thread.

 

$15 million in EPA fines?!

 

Formerly plagued with recalls affecting "hundreds of thousands of bikes."

 

...and no drivetrain improvements...

So this has been done before ? I know 4 valve technology is not new but I've never seen it in a Vtwin.

I think if someone is on the fence between an Indian and a HD, this engine might push them to the HD.

I like the competition between the rivals to push the technology.

I like motorcycles and what's not to like about what HD is doing ? I can only hope that Indian has something better in the works.

My Chieftain has been in the shop now for almost 3 weeks with clutch and transmission problems so I am looking for a second bike.

I can't afford another new Indian or HD, but I'm thinking about another 2000 Chief, has a great S&S evo motor.

Jim Feuling had 4 valve head V twin patents back in the early days of the EVOs.

 

He tried to pitch the design to Harley in the late 80s.

 

Quantum Motorcycles out of Florida had 4 valve Evo engines in all their bikes from 1998 to 2002.

 

The early 4 valve V Twins Indian had in the 19teens were factory racers Harley had some as well.

 

4 valves will move the mix thru the chamber quicker and does work well.

 

The Milwaukee 8s are an improvement over the Twin Cam design.

 

There may be some kinks to work out as the internal balancer seems odd, maybe prone to

 

wear problems like the Twin Cam 'B' engines had going on.

I had a Screamin' Eagle Fuel tuner as part of the stage 1 installed by my dealer in June of this year. No more of these from the dealership. That's what the Harley fines are about. They'll get the after-market suppliers next. These federal job-killing, no-account bureaucracies need to back off. Buncha assholes. I feel better now.

Thanks CD99 It looks like HD is just trying to make a big deal out something that was already produced.

I was looking at the Victory Freedom motor and I didn't realize it has 4 valves per cylinder.

So I wonder even more what Indian will be doing next.

Makes me wonder if they started the design of the new motor when the victory 106 came out. Seeing as the new HD motor is a 107 .. "Gotta make it bigger than victory" Edited by Mikehell

Indian ran a 8 valve motor in 1913 and were in height of racing....albeit the technology was different back then....HD is not the first.

True. Sales are still brisk for the Colt model 1911 .45. And it's still being copied.

The all new ChuckleHead Engine...

 

Why a *chain-driven* single cam engine?

 

Why not make it gear driven single cam like the Evo?

I wonder why they went with the single camshaft.. a step back to their 1936 technology? I know a couple of guys that still ride EVO's, and both have had pushrod alignment issues = bent pushrods. You'd think they would have started with a lower end design like the Sporty has...

 

Ah well - I got no skin in that game, so it don't matter.

Bubblehead seems to be catching on. I did like Cameltoe and Knothead.
