Welcome to Club SAITO !
Then there were the "Big Bang" desert racers and flat track racers where the vertical twin guys used custom cams and actually fired both cylinders together. Supposedly got better traction. Not really a Twingle imho.
My Feedback: (27)
I have a 2 cylinder1981 Suzuki GS450 that I use to just run to town if I need something. Several people have told me it was a Twingle. I know both pistons move up and down together. I don't know the firing order. I don't care what it is called as long as it is good transportation, but I always wondered about that term. If I need to go any distance, I have a 1984 BMW R100RS....That one is a Boxster.

Pedro,
Yessir a true boxer, a potent one at that.
The little Saito 60 TS and 90 Ts were sweet boxers too. Along with thd mighty FA-300 series.
Harley made a copy of the BMW and Zundapp boxers during WW2 as well. The XA, but only about 1000 were made.
Dave, The 16 horsepower 30.5 cubic inch sidevalve twin was just about par for that day and time. The WW2 Harley 45 cube "WA" made 23 horsepower or about 5.2 horses per cube. Compared to the 5.5 hp/cubic inch for the Triumph.
There was a fellow early on who made side valve, boxer twin RC engines. Forgot the name I'll see if I can find it.

I would love to see a pic of the Harley Boxster. My BMW Boxster always reminded me of a VW Bug engine minus 2 cylinders. I do have another car with a Boxter engine that is a lot more fun to drive than a VW Bug. That can be seen about half way down the page here:

Saito 300-T boxer crank.
Suzuki GS 450 crank shaft. Typical of Japanese twins.

Modern Triumph twin 90/270 degree crank similar to Saito V twin crank.
I looked at several to make sure, a lot of the newer, (verticle) twins have 90/270 degree cranks.
Gary, I wasn't knocking the hp of the TRW, my first Harley 125 Hummer had a whole 3.3 hp but it still went. It made me.

Peter,
20 sounds good. Have a couple Ham buddies coming over around noon to buy a couple vintage transmitters. Perhaps later in afternoon when they have gone home.
I re-routed the End Fed Half Wave and it hasn't been tried on 20m yet. We also need to try 40m sometime. One at daytime and another in the evening. Maybe even try some AM on 7295. I used to talk with a fellow in Texas nearly every evening on 40 using 35 watts and a 1953 era Ranger transmitter.

Thanks Dave.
Rare, Harley XA model from WWII. Would be right at home in Texas with the leather bags and loaded Winchester 70 in the scabbard! Or maybe even in Dave's driveway

My clever way to mount an IronBay regulator on a Saito 2.20.
My Winchester was a model 1873 Sporter in 30-30 caliber, 24", hexagon barrel which was not supposed to exist.

Yes it is, it's 45-f here and very damp, not my kind of day at 6:29 AM. The first thing on my agenda is to reassemble my Saito 150-s.
I am going to reassemble the right one.

Seems the cylinder on the left looks like it ran with the piston on the right and vice-versa.
Just sayin

I noticed the same thing, but not important from a measurement perspective, as there seems to be no difference in piston or rod geometry between early and later 150's. Should be easy enough for Dave to identify which cylinder mounts to which case however as one is factory finished and the other is a re-paint.

Everything is as it should be except the back plates they are switched. And yes I sent the left one. Aidan, that's a great looking field.

When OS stroked the 62v to make it a 64v they had to make room for the additional displacement. I think we already covered the new prop driver woodruff key.
Revised combustion chamber on the right.
Keyed prop driver, I wish I could afford one.

I wish Saitos had woodruff keys.
They opened the valve pockets, removed the heart shape area between valves at the top.
Looks like the plug angle that favored the exhaust in the 62 has been relaxed. The area around the plug has been raised a bit as well.
Hopefully they lowered the compression a bit, the 62 seemed a bit over compressed.
BTW, I actually prefer the taper collet drive, but can understand how sparky fliers would like the keyed drive.
A formed brass shim did the trick nicely for the D drive on my 95v
