People, those boxes are full of NIB engines. The boxes for the in use ones are in another container. The 56 was the first GK in OZ, I bought 2 back from Hong Kong (I went back for hand over) just to show local distributors they were in existance. I have on models a 65, 50 and a 30 (in the shed) and a couple of others out on loan. Old Far the beer (drinks) fridge is out in the shed annex with the spar. If you come to the Nats I just might show you around. Just found out that both the RAAF museum at Amberley and the Army Aviation Museum at Oakey are now closed to the public due to those idiots down south. Not good. Today is Lanzo Bomber (Saito 65) set up day. It is another of my competition models coming out of storage to get ready for the Nationals. Good to have a plan come together. If you like I'll post a few more shots of workshop stuff, now I am getting the hang of it.

At the bike races there were a number of HRD outfits and Vincent road bikes magic.

It turns out that the .45 I bought is an AAC ringless engine, my gut tells me that the traditional rich Saito break in is not the best way to go. Does anybody have any experience with the AAC ringless engine? Thanks, Dave

I wish I would not have sold my Saito .56 Hi-Cam engine. It ran like a clock. By the way, what did they call it a Hi-Cam engine?

John, I checked out some of Clarence Lee's tests of Saito engines and it looks like the term High Cam is used to describe Saito cams that have a broader, "toe" as Mr. Lee calls it. The point of the bump is broader to hold the valve at max lift for a longer period of time. It does not appear that the lift has been increased.

Check out the picture of the cam for this .80 he tested and mentioned the broader toe.

Good..you can come and ride shotgun

If it's good nylon you can bevel the tops of the beams,works for me.

Dave good fun to see your son doing some track days? on the r1.He must be an adrenalin junkie because the r1 is no slouch.In my job i get to ride all manner of motorcycles over the last forty years to now and with the aid of modern electronics re traction control via ecu and or mechanical,abs braking,anti wheelie etc via different control modes and mapping you really can use all of the available horsepower they produce now.You also have to be very discreet and brief wherever you chose to do that..or else a few weeks back i rode a 60's lambretta scooter,it was just as much fun in a different way.

Dave the ringless 45 you have sounds very interesting if there's no pinch point,how fine can they run tolerances from piston to bore ? and would you use a bit of castor as a safety valve.

Hi Hobbsy,

With respect to your braking in the .45, I happened across an article in MAN by Dave Gierke about the differences in breaking in a ringed vs non-ringed engine. I'm not certain if this is what you're looking for but I thought I'd toss it out. You have to admit, Dave G. knows about engines.

I'll break it in on the WildCat Premium Extra with 18% 80/20 syn/castor blend I've been using since 1992. While growing up I had a 1954 Harley 165 ST two stroke and a friend had a Lambretta, seems like the shifter was on the left hand grip.

On the .45 I need to do something about the rear facing air intake, it runs smack up against the firewall on the RCM 40. I modified a .40 this a way.

Thanks Bob, we wuz writin at the same time.

Ok, I'll bring the beer. Did Jeffie pay you that truckload of beer?

The only think I can think of is to get the ringless engine hotter quicker, so don't pamper it. Get it hot. I would run all castor for break in if I could get 15% nitro, all castor glow fuel around here.

Having built a few LT-40's, the 100 sounds fun but it's too big. You will end up with problems unless you doubled the firewall and added some reinforcement wood with epoxy. It's going to be heavy. Big prop. The LT-40 will do a lot of 3D stuff because I saw a guy do rolling circles, hovering, etc with one using a 46FX. I think W8YE was there that day too. The flat bottomed Clark Y airfoil will spoil the fun of the 100 though if you're looking for high speed passes.

Dave, if you get your printer to digitize your LT-20 plans and send the disk to me I'll send you my plans for the 4*20 as a swap.

Old Fart, don't tell people you were actually riding a scooter. This would something you lie about and deny no matter what. I know you are only joking, but that's like joking about carrying your wife's purse. A scooter? Really?

One of the quirks of the Club Saito thread is that pictures of motorcycles are allowed and generally encouraged.

hsukaria

I like bike pictures too, but I prefer the other pictures more. It's just that I have never owned or ridden a motorbike.

hsukaria

" about carrying your wife's purse. A scooter? Really?"

It's the European thing to do, I don't know about the Aussies though.

Hey, Old Fart. I was only yanking your chain a little. You would have done it to me.

Huskaria, no problem. We're all enjoying life around here.

Running in aac engines. I run in Saitos (all types and versions of the glo persuasion) the same way. However consider the following as recommended by Rossi. Set up engine with appropriate sized WOODEN propellor start and run to max RPM (this is on a new engine) and "introduce a steel rod to the prop arc and shut the engine down immediately. Repeat this process for no more that 5 "periods" or until target RPM is reached (each engine had a "target" rpm). You could try that though I wouldn't recommend it on Saitos. It was the factory break in procedue for its racing engines. Kill or cure and I have one that survived the process, a Rossi 40 (2S)

flyingagin

Man that sure sounds rough on con rods.?

But I can see that doing some good heating/cooling cycles.

I' let some one else hold and insert the rod. Sounds like it might sting a bit.

HA! you know me and yes i would have..

Huk jeffie never came up with the beer and i was bored sooo...i rode one of these.Can you forgive me ??

hsukaria

I'm not a biking guy, you will have to take that up with BLW and Hobbsy. BTW, I used to have a real VW bus like that one, a later model, but still...

Hobbsy

My Feedback: (102)

Well, since this is a high silicon content aluminum piston and an un-tapered chrome bore, I don't think it's going to take much to break it in. I am going to run 10% fuel and a Bolly 11x5.5 and a straight pipe, the stocker, at first then a TurboHeader. This one also has the bolt on head. A first for me.

Dave- what does Saito say about breaking it in?

OF- moderators can make that your permanent avatar.......har har

Over the years I had 4 VW vans. A 60 something with stock bench seat. A 64 ex-Polizei van with the 2 swing open side doors. A 74 pop up camper with split front seats and sliding door windows. That was the class party van in flight school. I had another one in Colorado- no heat, no defroster.

Rudolph Hart

Barry and huk you sure learn how to be a good steerer (or should that be sailor) driving a kombi in crosswinds at 70mph.Ok change my avatar

Dave can you post some in focus close ups of your 45 this has got me really interested cheers mate and no i would never make a joke about your little harley two stroke because then i'd have to tell you i owned a fifties bsa 125 bantam..i mean,they musta named that thing after a chook yes ?? and in the pre mix days where oil just fell out of petrol overnight meant that you had to shake the bike from side to side to remix oil and fuel.If you forgot to do that the oil that was sitting on the bottom of the tank promptly fouled the plug when you tried to kickstart it first thing in the morning rain hail or shine.Man i used to be fit.

ps dave it would be interesting to see how much blowby you get with the 45 some piccys ?

Hobbsy

My Feedback: (102)

As soon as I receive it I'll get some pictures on here. The one pictured is one I owned a couple of years ago. As for heating a nd cooling cycles there is nothing in a Saito's construction that can benefit from heating and cooling cycles. That is for sleeves and pistons made from ferris materials. Pictured is a 1954 Harley 165 ST, they wore 3.50x18 Goodyear tires.

PS, you see and read about that very engine right here.

Thanks for the laughs about shaking up the fuel in the gas tank. I have fond memories of not turning off the fuel valve and finding a flooded 2 stroke in the morning. I had a small squeeze bottle of trichlorethane to shoot on flooded plugs to clean them off. I had to do that a lot.

I have the right stuff coming from C&H Ignitions to convert my 1.00 to ignition. Adrian is a great guy to deal with. It took less than 5 minutes.
