Congrats on your win, Niklas, and thanks for the up-dated pictures of the inboard Tecnopower .21 motor. I like the idea of including three different head inserts with the engine. Is the inboard flywheel included? Richard D
 
Thanks Richard, Nope, no flywheel or carb included at this time. I used the Solinger wheel & Zoom carb.
 
Congrats to you with the win Niklas!

Oh no that cyliner will never work. It is only a 3port design.LOL :rolleyes: :D
 
DAM IT ALL. Wanted it to fit my MAC. :angry:

How come those backward eng get to have all the fun.

If it was just bigger could have made it fit.

If you need a MAC 21 P/S set I have one of the new CMB Valvola sets. I used another set for an upgrade to my son's 20 RR with a MAC. They work rather well.

Niklas Could you post another Photo of the Exhaust Side and Boost Side of the Liner

and if Possible the Piston ( Mainly Concerned with the Skirt like most men :p )

A shot of the End of the Crank would also be Great

Greg

Great looking sleeve are the top of the transfers flat?

What is the OD of the sleeve in English measure?

David
Updated info: Yes, the top of the transfers are flat & sleeve dia is 19.6 mm. So the sleeve of the M03 does not fit the M01 & M02 power head engines as they use a 19.5 mm sleeve.

like the sleeve.glad they didn't go with the 3 port exhaust!
What is it that you dont like about the 3 port exhaust ?
will not turn near the rpm of a large single port,with our set up.your mileage may vary
the three port design will give greater area in the circumference of the cylinder for evacuating the ex gasses. But I think a single will do a better job at it even though it dose not wrap around the cylinder as much. With the right angle of ears as i call them it will flow more I think. the bridge that the three port design uses to get the wide stance in the cylinder I think would do more to disrupt the flow than a single with wide ears. you can not make the top of the ex port to wide or the piston will catch in it. That is the reason for the three port.

David, you fell into that one. Jack did not make a statement, he asked a question.

You are preaching to the preacher.

Just keeping it light.... :rolleyes:

You have to have more projects going on that I do.
