114 M8 vs 110 TC

[shovelbill]

I personally think the M8 is a stepping stone to a split pin crank, totally water cooled engine. The 4 valve heads already out flow the RPM potential of the "tractor" engine, or a better description is an air compressor with fuel and spark.

The traditional sound is almost gone so why stick with a single pin and low RPM. Once the bottom end can take 8 to 10,000 RPM consistently the 4 valve head will out perform any prior HD engine.

Then HD will have to address the handling issues.

mayhaps the MoCo should have talked to Vern Ott........he came up with a crank in or around 1980........i've seen the original shovel version of this. .....my friend Dave owns it.......

here's some reading if you're not familiar with Mr. Ott.

He did indeed have a good idea. I think where the potential short comings were the way the pistons were designed, and the way the rods worked with them. They had an offset design, putting the rods out of center of the pistons. This required a three point cam ground piston shape, instead of conventional two point cam ground pistons. It was a strongly built motor, a shame the development didn't continue.

Maybe some day we will see it happen but I dont know if it will be in my time so ill just have to make due with whats available Butch

Reason I think what I said.

The EPA is going to force the MoCo's hand and they will have to ditch the air cooled engine. The VROD is a great engine and I'd love to see it in a touring frame but  think HD is committed to  keeping the 45 degree design, So split pin 45 degree V twin water cooled.

I'd like to see them open it up to 50 degrees, no one would really notice and would have room for a better intake.

Well Yamaha just came out with the new V-twin AIR COOLED touring rig. Don't count on Harley getting away from what they are now using for some time to come. Maybe something on the side like Buell or V-Rod, but they already tried that.
Just saying,

I'm thinking long term, like when all us geezers are gone.

They never gave the V-ROD a chance. I know many who say they would have bought that engine in a touring rig.

The Dealers killed Buel. Anytime I asked about one I got sneers and statements like, oh one of those, here try a sportster.

First I have hears about Vern Ott's design, but I have wondered for years why that design wasn't being used. I guess he and I think alike, only he had the money to make it happen.
