like your bike nice

 

So the results are in with a dyno tune and a tts jail brake on the ecm they have 79hp and 95tq.... that's 30,000 $ joke.
My 97 evo does that....

 

Speaking of the EVO's looks, my first thought when they came out was.............Why does Harley want them to look like Virago's.

 

Give it some time.

This engine has a lot of potential it just going to take time to figure out.

I don't know anything about tts or jailbreak or anything.

The dyno run I posted is bone stock.

Sadly, stock Evo's made what, 50 hp? These days 80 to 100 is common with an Evo.

 

The tts tune is in the dyno section with a zip file if you need to tune the 107 or 114

 

The thing is, the evo was the platform for all aftermarket scoots (still is mostly) and that's why we have 100hp evo motors today. It is also what drives the newer stuff to be better in power output or be left behind.

17 years of TC motors and there are none in aftermarket production scoots that I know of..

Just my opinion of course..

Griz

 

When the Evo came out, Harley didn't bother to patent the design, so everybody studied it, reverse engineered it, copied it and improved it.


When the MoCo brought out the Twin-Cam, every aspect of the motor was patent protected. Anyone making an "improved" version could face a lawsuit for patent infringement. You can bet your boots that the M8 is also fully patent protected.


Patents are typically awarded for a period of 17 years. This means the patents on the Twin-Cam are about to run out (or have-I don't know exactly when the patents were awarded). Could this be another reason for the new motor to appear right now?


All the aftermarket development of the Evo and the investment in this motor design by the aftermarket, is, of course, a good thing for us.

 

I suspect the design was so similar to the shovel that there were no patentable features. It was a safe design based on well established practice from around the industry. To patent something it has to have novel features which haven't been patented before.

They certainly found a way to defend their design from allcomers, especially the TC96! They seem to have relaxed things towards S&S in some way, as they are now producing replacement engines. Anyone fancy a 143"?

It's a long time since I last worked with patents, but it didn't used to be anything like 17 years. I wonder if the MoCo has found a way to use a registered design or some other form of protection.

 

True. At the time, they were also more focused on survival. In the '90's, I remember H-D tried to copyright the "sound" of the engine. Public outcry led them to drop the idea.


I suspect that H-D might license S&S to build that engine. They seem to have a close relationship with S&S. I heard somewhere that S&S actually did the "factory remanufacturing" for H-D in the final years of the program.


Patent length may vary in the UK versus US law. Last I knew it was 17 years from the date the patent is granted (not applied for). Then again, I'm a tool and die designer, not a patent lawyer.
