I have transfer ports on my mind.

Much thanks to Frits for the leaning tower of Piza article.

I could have sworn that at some point I saw a document about transfer ports from Wobbly, but for the life of me I can't find it among these 2500 some pages.

Am I crazy and imagining things or does such a document exist and if so can anybody point me to it?

I havnt done a paper as such , like the Exhaust duct one I did , but I have mentioned several times about the effect of stagger on the scavenging regime.
Reverse stagger ie RSA type favors top end and overev as it uses the larger width of the B ports being also higher to generate a big STA , also the A port being low reduces the vertical short circuiting
up to the Aux ports.
Normal stagger favors a wider power spread by suppressing the peak but pumps up mid and overev as well.
Both systems work by using the excess Blowdown pressure at TPO to determine what port flows when , and gives rise to the notion that the port to open first , flows last.

Thank you Wobbly and Lohring!

Lohring I assume what you have there is tidbits that were copied from the forum and saved? I'll go search around and see if I can find all of that in context, was it about a drawing you were working on (a clue for my search, I'll search through your posts).

We'll try to avoid that see you tomorrow!

Congratulations to you Daniel and to your team könig motorsport!

Hello together!

This is what we found in rotax 124 rotary housing
Expectet a more square inlet shape... dammed oval?
Slow opening and closing bit by bit.

Better give it a square shape?
For quicker harder pulse upstream the long duct to carb???

Thank you experts in rotary valve!

Apparently your embarrassment has scared us all, Neil; no one dares to post anything here anymore. Except for me, I'm too old to worry about losing face anyway .

We need another Ryger riddle, that put some life into this forum.

What became of your OP uniflow engine?

I believe ryger and his 2x banned minion were more fiddle than riddle

Anyone riding on GP50 revival next week?

[lohring]

You're correct. Unfortunately I didn't note where that information came from. It was either twostroketech.com or here. Wayne has posted a lot of very similar advice several places. Frits has also posted his porting layouts. A lot depends on what you want in an engine.

Dear Frits

Have a look what i found

Is this from you?

What became of your OP uniflow engine?

The design lives on my computer. Maybe advances in 3D printing will let me revive it. However, after I turned 80 I decided I needed to limit my projects to less exotic things. I also transferred my big mill, lathe, and cutter grinder to a younger friend who will use them a lot more. I also donated my engines, tooling for cylinder modifications, and inertial dyno to another friend. He has already built some nationals winning engines for himself and some friends. With the above and my newsletter articles I hope I can pass on what it takes to keep the hobby and two stroke knowledge alive a little longer. I have been encouraging them to read twostroketech.com and this forum, but without much luck. I'm off to what may be close to my last national championship race in a few weeks.

I will be there and make some photos. Bump me up we'll have a chat, can't miss me, guy in a wheelchair with camera. I will be with my friend Cerar, he is driving freetech.
20+ riders will participate. I think it is a record. And it's 10th aniversary this year.
Will you race?
