Commando High Speed Stability

If there is a 3rd or even a 4th element preventing the twist-tip of power unit on the main iso supports it don't matter that much if steady is above or below the engine. Peel's Watt like lower two links, way out of line of the two isolastic she didn't need a head steady so only thing I felt improve on Peel with it was eliminating another layer of sense of a motorcycle under me from the nuisance road texture and wind gusts effect on fork tremble vibrations as road holding still world class or beyond. I was rather surprised by the extra smoothness which is felt as similar to engine vibes getting through but ain't.

Phil,
It's quite alright to throw money at a Norton. Just make sure that it gets spent wisely. The TT100 tyres are old technology. The pressures you are running are inadequate. I run alloy rims (Morad) in 2.5" x 19" both ends. With 100/90 Avon Roadriders with 34psi rear and 32psi front it has a nice light touch to the steering with absolutely no stability issues as the speed gets higher. This way, when the rear wears out, the front tyre gets fitted to the rear and the new tyre goes on the front. This will make a big difference to your handling. If I had 200 litres of kerosene I wouldn't run it in my Norton "because I already had it".

Jim Comstock's beautiful headsteady is worth the ask. Simple, neat, no adjusting. Simple to fit and does the job. Ikon shocks are the business. Made just down the road from you. Not cheap, but worth the ask.

I use the same setup and switch out tires exactly as stated. So happy. But I use a Dave Taylor H/S on my ride.
Cheers,

basicly i was 20 years old the the throttle had 1 position and my mates had jap bikes i always had the advantage in the bends until one night i was hard over on a left hander on a dual carriageway there was a ridge of tar that went across the road i knew it was there and had become used to it but this night the whole bike whipped and stepped out sideways i ended up in the outside lane my mate was right behind and saw my bike get out of shape the next day i was was pulling the back wheel around and noticed the engine moving side to side so i removed the tank and found the problem,i was so green back then i had never had the tank off before never knew it had a headsteady never adjusted tappets/isolastics or changed the oil !!! ,,,,baz

Sounds like you were lucky the torque didn't rip the motor loose and tilt it forward or even spin it like a propellor from the front isolastics. I'd say your problem was certainly less than subtle. I've just spoken with Jim Comstock and I'm planning to get two of his head steady's. All my old unwanted bits and pieces I flog to ignorant Triumph owners. Mail delivery only.

Speaking of nasty things happening, one day I was riding the combat in Sydney down the busy Hume Highway when a truck just forward of me in the next lane hit a disgracefully huge ditch like rut in the road. I hit it too but the Norton handled the jarring bang okay. But then I see a huge girder like hunk of steel lift off the truck table top and it's hurtling airborne straight at me. I thought it was all over but it crashed down just short of me and with a violent swerve I missed it by inches. Absolutely scared the crap out of me and would surely have broken my head steady, which in the human anatomy is known as a neck.

years ago i had an 850 mk2a with the box type headsteady i had a handling problem with it that i eventually traced to the headsteady both threads were ripped out of the frame on the rubbers and both triangular plates were bent outwards!! on the 750 i have now i have an extra isolastic mount under the gearbox i can run the bike without a headsteady fitted it really isnt needed it makes no difference to the handling i believe the kenny dreer commandos had no headsteady fitted at all,,,,,,,,,,,baz

Mine is a Kenny Dreer Commando and it had a normal headsteady which I replaced with the Dave Taylor setup but made no difference .

One has to ask you edward, why did you replace it? I gather you had a concern about something to cause you to change the head steady.

Re handling of commando.

Get forward in seat with gut on tank( getting the weight forward ) it also allows you to hold the bars lightly so less weight on the forks, therefor easier to steer. But don't take it too far !

Far too far. But the front is light!

That's a sake-sucker auldblue, they do that all the time. And that's an old photo of me, I've changed significantly, probably put on another 50kg since then. Broken every Commando head steady I've ever sat on. I guess you shouldn't sit on the head steady.

I see your attire hasn't changed all that much. At least, you're getting a better hair cut now.

I wear what I can find at Vinnies, which isn't much. Haircuts are by Alf's Barber Shop in Mossvale. $2.50 a pop. Takes just 5 minutes with a plastic bowl on your head. It's called "The Commando Cut" and extremely popular in Afghanistan.

The weight is an issue I will admit. Running tyre pressures 32/28 psi, acetrol told me there should be a 1 in front of both of those back/front figures. But the TT100's keep bursting and my space frames are snapping in half more frequently than pete.v is blowing mains on his hybrid combat!

Phil
 
And whilst I'm at it Nathan,
This TT100 3.60 you told me would improve my handling, just what am I handling?
And how do I fit it over the 4.10 already there?
The bike shop told me to bring the wheel down and they'd fit it for me. But I can't, the wheel's attached to the bike.
Bloody sake-sucker wrench monkeys are having a lend of me!

It ruined my Commando Cut.

Obviously hobot left the scene very quickly after the fuzz clocked him at 300mph!!
And he was wobbling and weaving on one wheel all over the road before the tree got him!
Or is hobot still under there, hiding from the fuzz?

All reported Commando severe wobble and weave riding home later that night.

Not for nothin' and just a point of interest if anyone really cares. I have a '68 BSA Thunderbolt and the old factory workshop manual for it covers all the 650cc A10 variants available for the world market at the time. For the US market the wheel diameter is 19" front, 18" rear. For the home market, (England) it's 19" front and rear. My thinking is it was a marketing thing. That 19"ers both ends were what the chassis liked for best handling, but a fat tire'd 18' rear is what Americans thought spoke performance. "It's not how you feel, it's how you look...And you look Mahvelous" - Billy Chrystal.
 
This is the real Phil on the streets of Mittagong......the high speed wobble is due to a flat spot on the left rear wheel.

Never heard of him, must be an imposter!
Yes I've heard this Biscuit, the Roadster itself was styled specifically for the American market, as I understand it. But the world loved it anyway. I asked Baxter's why they fitted an 18" rear to my bike which they had built and the short answer was, don't really know Phil. Everybody does it. Surely it can't be too much of an issue (handling wise) or everybody wouldn't do it. But stranger things have happened. Some blokes even own BSA Thunderbolts if you can believe that!! (I love em).

As far as I know, Triumph was standard 18" rear and 19" front, all over the world, but I'm no historian on Triumphs. I'd better get this bathroom finished, hobot is refusing to ride peel until I can tell him what size wheel he needs. He's over at Wes' house having a major dummy spit!.

ps, me with the wig off.
