Strange. My 50 and 496 were Millennium. Never saw an issue when pulled. Both run in on dyno. 50 a billion times.

496 was wiseco. Didn't see issues.

Any kiwis got one of these lurking about I want one to make a crankcase breather for my Ducati, cough couch 4t project.
That way despite its over complicated top end with wizwams a tick tock clock pieces It will it at least have a 2t Reed Valve.


Its normally found an early Homeliite chainsaw
I thought there was one in the old mans shed but the ratio seem to be more shed than homelite Reed Valve.
there are jonseerd and old sthil

These are smaller then they look

Finally!!
I got this 'overkill' Kawasaki engine started.
It´s been a hectic week, actually for no reason.
But i wanted to start this bastard of a engine for you guys =)

It´s a Kawasaki kx250 -96 engine
Equipped with balanceshaft from Tecate.(parts from tecate but house built by me)
Lockup clutch.(built it myself)
Rotating disc intake system(built it myself, some parts from Rotax can am 250)
TM racing cylinder(ported by me, resleeved by me)

So it´s a real hybrid of things, like a frankensteins monster.

Hope it produces monster power later on also =)

I got few homelite reeds Husa, if you need in pm

While you are cleaning out the shed, try get the T125 closer to the door.

I just noticed where you are from what a beautiful spot. Thanks for the offer, I don't think there is a spot in the world further away from where I live.
I am sure there is some in the shed somewhere, But Grumph will attest it's a jungle in there.

[yatasaki]

If you need.. it's on me, who else in the planet would need 60years old chainsaw reeds to put on foulstroke

I plan to let exhaust side crankcase inhale as much air as it can and blow fuel/lube oil for a 15% rich mixture on underside of exhaust piston to keep it cool.
Inlet side is only allowed to inhale a third clean air.
The two crankcases are connected by a pipe and contra valve.
(Not shown yet)
The scavenge air escaping through exhaust port will be clean, cold air.
Rest will be correct lambda and stay in cylinder.
A simple oxidation catalyst will be fine.

Below are pictures of my piston ported, crankshaft scavenged, opposed piston engine. It used crankshafts and crankcases I had with adopter plates to a cylinder. The pipes and gears between the crankshafts aren't shown for clarity.

Was it a simple job to make the geartrain work satisfactory?
It has been a sore spot on quite some opposed piston engines.

Is that made of wood? ECO.

Here is one in actual hardware. Waiting on time/money and interest to finish. (My interest is elsewhere pleasantly)
