Transfer ports

[DieselTech]

I'm new to these 2 stroke engines & was curious on the closed transfer ports, can someone show me a picture of a good transfer port, I've been doing alot of reading on here, & they talk about transfer port shape & redirecting the transfer ports towards the intake. Can someone show me this or explain it. Even a drawing. I'm wanting to learn porting in time & just wanting some direction.

Check this out.

The new ceramic coated cylinder's

I have a few of these 48mm bore ceramic coated rather than chromed cylinder's and as usual checked them out before going ahead and correcting transfers and porting them.They are very nice straight and even casting's,port timings are a little weird but fixable,here is what I found! With a 38 mm...

Some guys use JB, but I'm not a fan of anything that could come loose.

Compare the shape to the one you posted a picture of.

Thanks that's good info, my cylinder dont have open transfers like that. Do they refer to them as a closed transfer that are not open on the sides of cylinder?

Heres pic of the transfer port, the steel sleeve has a over hang, with a lip covering the roof of the transfer port. I guess that's what it's called?

Is that bad? & needs corrected. Also you notice there's a knife like edge pointing towards the intake, does a person need to keep that shape or knife edge.

Not bad, but not good either. Lol. Knock it down level. Keep the flow to the intake side so it swirls in the cylinder from intake to exhaust. If you change that angle and its wrong, it may short circuit and you'll lose massive amounts of power.

As in knocking it down, do you mean make it even with transfer port roof?

Yes sir. Nice and even or you get sprites on ya butterfly wings on the piston.

Sorry bro you gotta angle it the other way, I'll take down my other picture. It should go this way.

This is what mine looks like afterwards
