No, I am not a Chinese spy looking to build the next clone "XXX" engine.....

I just like engines, and modifying them, studying them, etc.

Could anyone supply the port timing specs, and possibly pictures of the ports for the DLE 20, 30, and 55cc engines? They run quite well, and I would like to study them but can't afford to buy an example of each right now.

Thanks for any help or info,

Jody posted a bunch of picture of the DLE20, inside and out. There in the DLE20 thread. Just click the picture icon and scroll through the pics till you find them.

I doubt the manufacturer knows the port timing.

Hee hee....

As for DLE's, I only have the 20. The timing is not all that extreme but the engine is all ports. It is a open port design and has schnurle type intake ports including a generous boost port.

av8tor, I do not have the port timing...but here is a couple of photos of my DLE30cc engine showing the ports. I may have more photos too. Capt,n

To obtain the port timing takes a lot of time and work in obtaining accurate measurements. Usually something I won't give away. With only a few exceptions the port relationships in the Chinese engines are pretty much the same. Copied from Zenoah. Loosely copied, but copied.

Thank you very much Captain. Oh yeah, they do have some serious transfer area don't they?

Captain, any chance of a shot or two of the exhaust port?

Thanks again John.
