I just broke in the above mentioned Saito .56 with F on the right lug.
Started at 10:09 AM, finished at 11:09 AM, purely an accident.
Fuel as always Wildcat 10% full syn.
Prop Xoar 12x6
Plug==Stock/H9 Super Plug
Exhaust==later Saito revised muffler and pipe
10 minutes at 1,000 rpm intervals
After 55 minutes
Max rpm===9,490 determined at one click below peak, peak wondered up and down a little.
Idle 2,020

During the 6,000 rpm period the rpm increased to 6,600 without my touching anything.

Hello Capt, The 4*40 kit has a "near" 60 in ws and the 4*60 kit a 71". The ARF's a 54" and 64" respectively. Clipped wings!

That 12 x 6 would be too small for a YS 63. On 20/20 the YS would turn close to 13,000 RPM.

I ran an APC 12 x 7 on mine. With 14% nitro, 14% synthetic and of course, 2% castor fuel with the Enya #3 plug it would do a healthy 11,250 RPM. The idle at 2000 RPM was very reliable and could easily go lower.

I started etching my mufflers with the correct size on them. The new Saito Revised exhausts have flat sided nuts that should hold better.

No sir, they are hexagonal.

I think that's a fair question jessie most harley riders are known for it.A big tankslapper can alter the shape of nuts too.

Dave on the second or third tank during run in it's not uncommon to get bigger than 600 rpm changes on run in without touching the throttle.I'll include a pic of a nice flathead harley letterbox.

I did the .56 break in with a single 16 oz tank, it took an hour to use it all
That's a nice Harley with it's McCormick Deering seat and cow bell headlight and a true flat head. I gotta check the spelling for McCormick, I got it wrong. I looked at that word for my whole child hood.

A 15x8 or 16x6 for the 1.25 and a 15x6 or 14x8 for the 1.00. Have you tried the .82 yet, Thanks, Dave

Any Harley is more reliable than that ugly Erector Set bike you ride.

I fibbed about the tank size, it's a 14 oz tank, I am going to run the .56 with a TurboHeader and APC 12x6 in a few minutes.

You're certainly welcome.

I just put 35 more minutes on the above Saito .56 with an APC 12x6 and a TurboHeader, the new rpm is 9,960. Now I'll have to do them separately to see who did what. A new idle figure too, 1,500 for two minutes.

Trying to get my planes in the trailer and running out of room. 7 in there so far, 3 or 4 more to go, and one is the big P-47. I may strap that to the workbench and move the SSE elsewhere. Debating whether or not to put the Twin Otter in. It is such a PITA to take down and put together.

Well,
Got out to the field today with the fresh Rascal 80. Nice flying plane. Flew straight and true, no trim needed. The re-freshed Saito .82 ran very well. No run in time, straight into the plane. I had some concern as this is an inverted mounted engine and the carb is well above the top of the tank. Fuel draw was strong from full to dry. May be trying a 14 inch prop as there is a lot of ground clearance.
Also took along the old Toledo Special, also sporting a Saito .82, the first .82 I ever owned. Shame they don't make that plane any more. I am thinking about scratch building one just a bit larger.

Next project is to build another old-school Sr Kadet three channel, rubber band wing, tail dragger for the Saito FA .40. Lost mine last year after over 35 seasons.

Ouch Dave, that cuts to the bone!

Nightmare scenario, riding anything that is less reliable than a Harley!
After all these years riding year round, taking two and three week long trips.... Always got where I was going and always made it back without a breakdown. I bet I am long overdue.
Please let me know just which one is the "Erector set" bike :0 I will have a look at it before the next trip.

This one?
or this?
Ah ha!
Or any one of these derelicts
?

Just pick one, no Harley has ever disappointed me, not ever. And yet you rag on them.

The Saito .56 is ready to fly and will do so as soon as Geri is well.

what prop for the Saito 100 ??

if this helps,, see my link below,,
people have reported turning an APC 15X6 on their Saito 100 at 9600 to 9800 while burning 15%, and an APC 14x8 at 8800 to 9300 also on 15% (for the most part all numbers were peak RPM), yet some people reported lower numbers..

I will brake mine in with the APC 15x6, but on the plane (VQ P-40) I plan to run mine with an APC 14x8, a 15 inch'er is going to be too long,, besides, I want to try loading my 100 around 9000.. loading my engines a little more than I have in the past is something new I want to try on all my engines, I will also try a Hotter than usual Plug. my thoughts are, with loading the engine more I will loose a bit of Prop Acceleration so less flame outs, but the Hotter plug will start the Flame Front sooner and that will create more torque, peak RPM will be down a bit with the Hotter plug but the engine should run well, once the 100 is broken in I have 3 different 4St plugs to test, A) the stock Saito Plug, B) OS F, C) K&B 4St plug.

BTW, Angie called me yesterday, my new HP 61 RI GC was in the process of being built, I had a funny feeling knowing an engine was being built personally just for me, it will be shipped next week, I was going to put my OS 50 Hyper Heli engine in my Wold Models P-40, but at only 2oz heavier I now LOL am thinking about putting that very cool HP 61 RI in it ..

Jesse what's the diff between a harley and a vacuum cleaner? the position of the dirtbag! just kidding,you and dave have a lot in common...did you know dave has lusted over the motoguzzi mgx21? and i like it's gothic styling.Motoguzzi's are considered an acquired taste over here ...as is taste actually....

ps dave glad you liked that rustic harley letterbox,best i've seen.

Thanks Jim, Dave also has a Saito 100 that I rebuilt because it had a badly busted cylinder and crankcase. It was practically a new engine by the time I replaced everything. The Saito .45 with the removable head may have been mine also.

Yep, that had been my .45, I ran it once for about 15 minutes, it's an ABC engine with no piston ring.

Thanks Pete, yep that is a novel bike, it wouldn't make me hate Harley's though, nothing could do that. The only thing disgusting about it is the ugly bat wing looking wind shield and I hate those on Harleys too. My neighbor has a mail box post made of welded together horse shoes in a big long exaggerated curve. It's painted the same color as the Harley like one above.

Early .65


Metering slot.
The Saito .65 Dave showed has this metered carb and that's the reason for the special HS needle. This .65 has 50 sized valve springs, the spring seats are machined for them. Note spring clip holding the carb barrel, it keeps side pressure on the carb barrel keeping the barrel tight up against the fuel port, I assume to insure accurate metering.
