Rowley's 400 and the Magic Tube , hijacked version .

If asking hobot about mufflers, my 72Trixie is bone factory parts but carbs modified opposite the concept of too rich on poor draw in states. Peel in her prime was better yet with perfect fairly fast wide throttle openings to be abot to on set and control a constant spin that does not spin up to spin out nor bog buck and stall in lugging conditons in soft soil/mud, soggy layer of leaves. My P!! was beyond belief in 600>9000 throttle response beyond both above 2 Combats. P!! would plow through deep dry sugar sand like in elevator ash trays throwing a wake of sand out about a foot like a boat with hands off throttle Pow Pow Pow Powing at just below 600 rpm in deep woods of N Fla. yet when a steep rise ahead could snap up instant set constant rear rooster tail to scoot over the crest then let go for the sightseeing in two rut tights delights. Sometimes it would plow its 2 inch low frame chin into center hump but just blasted through it with deeper sound from engine. Never ever had anything so perfect responsive start to finish any gear any time as that old school Beast. Trixie has 5 carb mods that all onset richness sooner easier to keep me pleased on lack of mere factory Combat horsepower.

Do you have mutes installed though ?

Otherwise all chitchat is irrelevant ??

After some early dicing with the Pure version, the Hijacked version has pulled into the lead and appears ready to lap the Pure version.....

With bells on.....

(old english expression, something to do with horse gear ?)

Love the horse analogy. The pure Rowley version leads by a country mile for primary evidence while the hijack version is so full of the stuff from the horses (just not the horse's mouth). Not to say you won't find a gem if you fossick around in it.

More restrictive exhaust changes are known to richen a/f but i still do not see how a richer feeding spray tube could help a bogging over rich condition. Commandos are crazy making complex confusers.

If its purely the mutes restricting the zorsts that are causing this (reported) problem,
and muteless the cut spray tubes go like a cut snake, then we may be getting close/closer to some sense out of this conundrum...

Anyone say for sure when decibel limits came into play on bikes.
I'd have said after the inital 850 models appeared, but may not be the same everywhere.
??

I know what happens when literally pouring raw gas in a moving vehicle bogging d/t fuel restriction, it takes off but if not stop the pouring or careful slower pour it chokes and dies. I had pinched hoses, covered drains and emptying tank cause a long draw out bog down on WOT till dead or an number of vehicles. An over rich event enough to prevent acceleration must be longer than it take to turn throttle. Accelerator pumps only work a squirt or would kill power. Therefore I think the problematic 850 may of made an initial sooty puff on insignificant instant of restricted exhaust richness but then lacked enough sucktion (ambient pressure difference) to draw enough fuel in to barely keep running on tire fly wheels help. I am still stuck on concept of
cut tubes are to enrichen not lean.

A serious investigator could try to reproduce the early bogged 850 set up with monitoring and see what is doing what. Maybe Amal still has some info on this.

It was negative G at the commencement of a dive that caused the cutting out. Read the bit in your link about the Spitfires rolling into a dive to avoid the problem.

Click to expand...

And then read the bit 2 words later that the engine would still cut out in a steep power dive a moment later. ?

Click to expand...

Where?

The British countermeasure, a half roll so the aircraft would only be subjected to positive G as they followed German aircraft into a dive, could take enough time to let the enemy escape.

I'll have to read up on it and hunt it down.
Maybe some day.
Doesn't that happen with anything with carburettors falling faster than gravity ?

Dear rohan.
War thunder is a video game. Gamers 'fly' virtual aircraft in 2013 not real aircraft in the 1930s and 40s.
If there was a video game with Norton Commandos then gamers would discuss 'riding' virtual bikes and 'tuning' virtual AMALS.

Actually that sounds like a good idea... Save a bleedin' fortune !!

Really, you don't say. I never would have guessed.....

Some of those 'games' are terribly realistic.
The F1 crowd use one of them to learn tracks ahead of the races,
and apparently the V8 crews have something similar.

I once did a 232 mph lap of Indianapolis (speedbowl) on one of those machines, and was amused to see someone did a similar real lap a few years later.
Apparently using a very similar setup (?) to the game version, which is endlessly adjustable.
Life imitating art ?

Good idea about the Commando game.
A lot of coding though.
Perhaps with a more modern machine then ?
Harleys are popular, wealthy owners. !

Yep. You can reinvent physics and ride a Norton upside down at a gazillion miles an hour and push a button to get a new life all in the comfort of your keyboard while still in your pyjamas.
Ta.

Flight Simulator is fairly accurate to planes performances, if you look in detail.
If it can't do it in real life, the more recent versions won't let you do it either.

Having once managed to put down a 747 on an aircraft carrier, after a lot of tries.
Although not necessarily in one piece.

But we diverge....

Re: Rowley's 400 and the Magic Tube .

so finally, there were no press onboard as you stated,

and i doubt the vid you mention below exist, maybe you saw this one
https://www.youtube.com/watch?v=uw2qPLEgKdQ

finally, in the needing air thread where you mixed aviation and norton's, and were called on a claim then didn't answer,

it's not always (as you claimed) full rich for take off with piston power

i'm interested in the "Press on board" part you mentioned?

Click to expand...

I've seen a video taken inside the passenger cabin, where the world outside the windows turns turtle and back,
and the drinks on the tables don't even slosh.

Maybe there was more than one rollover then ?
Although I doubt it, the pilot seemed very chastened....

Click to expand...

No No, the TV doco said it was the 707, and folks with drinks on board.
It was inside a large jet. Early-ish too, but don't recall specific details.
The word used was Press.
Maybe they lied. Wouldn't be the first time something on TV had been invented.
Remember though the Captn said something there about "proving it was safe", and folks experienced that.
The Company Pres only found out from the footage... (?).

We diverge muchly here though.
Research it, and report back....

we diverge alot because you mix aviation and norton's and are very loose at the least, with the aviation part

then when you are called on what you say, you turn on your diverge button,

i'm not looking up evidence to back up your aviation ramblings, your "press on board" has already been refuted,

you provide evidence to counter or support that claim, or any other you make

Let's just drop this hijacked thread and pledge to keep the other one pristine after deleting the last posts from that one.
I am now pretty sure that the 'TV doco' was vague recollection of a 'realistic' video game on the TV/computer screen.
Ta.

TV doco said press on board.
Showed drinks on table, with the world going turtle through the windows.
It seemed from the commentary that this footage was what the Co Pres sighted.

Note that needing found a reference to the pilot saying he did a chandelle,
but footage from airfield sure didn't show thats what he did !
And then folks here disputed !!! that aircraft can fly upside down.

You can refute all you like.
Lotta Boeing history stuff out there.
Go ask on the aviation forums, plenty of rivet counters there.

Dear rohan
I did not find a reference. I provided a link to the pilot saying in his own words what the manoeuvre he performed was. What the popular press called it in 2009 is not correct and the video may/may not even be the one Tex refers to.
This is primary evidence provided by the man himself: you are calling him a liar. Here is the link again: http://www.airlinereporter.com/2009/11/ ... x-johnson/
