Hi all

it very fast ( 130 MPH ) with the SS cam I just got to watch it as it runs freely past 11,000 RPM's if I let it ( standed was about 6,500 RPM before it valve bounced), if any one like to know more about the bike feel free tha ask any qeustions, I

How about sending us a pic of that tacho? And what make of valve spring are you using?

Hi all

Well I truely stirred the pot up with my claim of 11,000 RPMs, I have never taken the bike to those RPMs but when I build the bike I followed the stage 1 hi performance moderforcations in my workshop manal, it said in the part about the SS cam that it will run freely past 11,000 RPMs if you let it, I have opened the twist grip fully in 2nd gear and the motor will run freely but backed off before I over done it (don't like things flying apart inside my motor) but I have no dougth that it would... In my younger days I use to do a lot of burnouts and hi speed runs with this motor and have done a bit of damage as well (excessive wear in the cylinders, hairline cracks in the crank cases) that is why this rebuild to replace the crankcases, I'm alot older and wiser now and look after my motor...

With the featherbed frame, it's shorter than the Commando, I have replaced most steel parts with aloy and the bike is well under 300 pounds the Commando is 412 pounds dry, I say it would be more between 250 and 300 pounds and I will be getting it weight soon when its back on the road, we lifted it of the work bench the other day, I was at the back end and a friend was at the front, we both picked the bike up and lifted it off the stand, it was heavy but wasn't to bad, I have no troubles lifting the rear off the ground for my daughter to put the work stand under it and I'm no body builder...

The Joe Hunt maggie, oiltank and a few other part came from Lowbrows over from the USA, they were made to order and it only took less than 10 days to arrive at my front door here in Australia and for only half the price we can get anythink from here, very happy with the service, I also don't run a battery which also saves a lot of weight, I run a Sparx Battery Eliminator to run the lights ...

Ludwig will want a pic of the scale reading. No funny business. Big, fat wideline is going to cost you a few pounds. Seems like a lot of stock parts which aren't light. Looks like a stock tank. Ain't light either. Maybe things weigh less south of the Equator. :mrgreen:

Stuck throttle ran Peel's unloaded 2S cam to 11,000 rpm, maybe more.
Conclusion is get a rev' limiter as only Sir Eddie can get a Norton to
live @ 11,000.

I'm a bit anal on Peel project mass wise, so very interested what
your works out to. Combat manual lists 412 lb, but they didn't
come with mirror or signals. I'll be happy if bike+me = -550 lb.

What I'm curious is how harsh it handles turns and if you've
the nature to wisely press them to sense what's happening.
I got no more respect for fat tire moderns but on freeway
opens. Its torquey skinny tire edge cycles I'm pensive
about matching.

Mainly curious what you sense in the Featerbed twists or
jutters. i was under impression it was not up to Commando
power but an isolastic adaption changes the whole equation.

I wonder if it is coincidence that I am reading this thread and watching Monty Python and the Holy Grail?

Hi Everyone & you Ash,
I'm inclined to be sceptical about this bike like others in here. 130 mph maybe, - brilliant handling, Yes definatley - 11,000 rpm, I dont think the gearing on the drive matches the rev counter gearing as was said earlier in here.
Could it be that your taking the piss Ash ? (No offence mate) Well maybe a little.
My 750 cruises at 90mph at 5000 rpm on my way home from work up the M1 motorway. If it did 11,000 I could catch Concord.
Cheers all

This is great keep it up it beats the c**p out of working and it's raining outside...130mph must have a neck like Mike Tyson :lol:

I hope everyone does not think these whimsical tales are common to all of us from the Antipodes. With the cautionary disclaimer that imbibing copious quantities of the amber brew have proven to dramatically increase speed and power and drastically reduce weight and the other various effects of gravity!. :mrgreen:

I agree that computing while intoxicated (CWI) should be reviewed by our dear lawmakers...

An unfared Commando at 130?

RS

Under 300lbs with a featherbed, iron barrel, alternator etc?........380 if it weighs an ounce!! (that is in Imperial Lbs, with 16Ozs to the lb, just in case Antipodean lbs are heavier ................oh wait, because he's upside down on the bottom of the world, anti-gravity kicks in ;-)

I know my Seeley, which has magnesium hubs, light crank, alloy barrel and every weight saving mod I can manage and afford still weighs 285lbs, my race featherbed weighed 330!!

285# is remarkable bragging rights to me, so is 330# in your Featherbed.
Ms Peel Combat with lighter flywheel and drilled brake rotor
and heavy chrome parts weighted 367# with about 3 gallons
gas + oil. Later reduced exhaust system mass by about half via 2 > 1
used small 1.2 ah battery and removed luggage rack for a bit
more spunk to toss but didn't weight again.

New Peel version as lost at least another 20 # mostly in wheels
and swing arm. Hoping for ~ 1 hp per 4lb of bike and pilot,
or 1 lb-ft torque per 2 lb of bike*pilot. That includes
added mass of blower and 2 quart water tank and air station.
Thinking about velcro on ride leather buttocks and seat notch
and inside knees and side of IS tank.

You Upsidedownies are building up a reputation, I'd say.... :mrgreen:

there are lighter ones around too..don't forget, no alternator etc, the bare motor is 25lbs lighter than a standard one, Seeley chassis, mag wheel hubs, belt drive.....it's a race bike.....no silly isolastics and other big lumps of stee to haul around. Actually, I think Ludwigs road bike is more impressive weight wise!!

Whoa! Thanks so much for pointing this builder out Tim.
Mass 353 lb, 120 hp, 100 lb-ft torque gives 1 hp per 3.3 lb
and about 1 lb-ft torque per 3.53 lb bike. If we plug in 175 lb pilot
give 530 lb total for 1 hp > 4.4 lb and 1 lb-ft > 5.3 lb mass.


I am so glad to know of 165 mph road going Commando is livable.
A race faired 750 [Mick Hemmings?] was clocked 175 in France.
I'll have to pester him on type/rated tires fitted.

Wouldn't it be a kicker if Peel's reviewing by me turns out to
be a bit conservative to carry around her 600 watt charger.

Steve, read this for a while:

norton-from-australia-t5731.html

Please remember that everything you read is not actually fact. If you forget I'll point you to some bonsai kitties...

Sorry, that was abit misleading: That was meant to refer to the 127bhp/l of the Village people - and that claim is allmost a massive 20% higher than Maney's. Given the fact that his numbers are from a full race engine with probably a rather short live I think that this is possible even if it might be a bit on the high side. As you've put engines on dynos you know the game, correction factors can be and are used in favor of your marketing claims. However the 127hp/l for a Roadster - no, I don't believe it. Tim

Thanks for pointing me at the prior discussion of Village engine claims.
I plucked hobot doubting Tim's comment as similar to my own this time.

I've done business with Steve Maney and still touch base by email.
He stated that his 920 full race engines are only run willingly to
7200 where 100.4 hp is measured. I do believe Maney's engines
could survive a dyno run to 8000 rpm to also claim well over 100 hp
by fudging standards of data interpretation factors.

Heck Tom Dourin's dyno graph in his ads reached the 8000 line
with the blower slapped on otherwise bone stock engine.
Yet in later installation instructions Drouin emphasized
6200 rpm as max. But that was mostly d/t blower limit with a
heavier impeller than his last models like Bruce's and mine.
Some have milled down impeller to at least 1/3 less mass
I do so want to try 8000+Drouin on a couple of dyno to judge by.

Hope the rider from OZ gets back with ride reports to judge
the important stuff to me.

Well, it's a featherbed frame, not a Commando, and that helps keep it a little more compact, but those high bars are going to make 130 mph kind of hard to manage.

I took my AHRMA race bike, a featherbed Norton with 750 Commando engine, to Bonneville in 2001, and set records (all broken since) in three classes, one at 131.113 mph. That's a two way average. This was a serious race bike with a full Axtell package in the engine. I think it would be hard to push the same sort of bike much faster with a 750 Commando engine, unless you spent a lot of money on the engine, and a lot of time on the dyno. This is a shot of me on the bike while waiting to start a run,



an after a run.



Because of the high elevation at Bonneville, and tire slip on the salt, the same bike would be a bit faster at sea level on pavement. The same bike was clocked by the AMA radar gun at Daytona in 1985 at 141 mph, although with a different exhaust system.

Just adding some persepctive.

Ken

Just for comparison my Manx weighs in around 300lb. It's a magnesium 500cc single with no electrical system whatsoever, no lights, no alternator, no voltage regulator, no wiring, alloy mudguards, magnesium wheel hubs, alloy engine plates, no speedo or cable, alloy fuel and oil tanks and magnesium housed gearbox with no kickstart mechanism, etc, etc.

I could use some tips on getting my Manx down to 250.

Eight-plus pounds, I seem to recall.

Gday ken,
and a very interesting perspective it is!! What a blast on an unfaired bike at those speeds, got to have strong neck muscles to keep the head on and in line.
I tend to think aswell that the Johnny Walker wisdom was riding high stating that a Commando motor can rev freely to "Made in the U.K."(11000 rpm). It may do it a few times but not good for longevity. Could we see a video of it maybe??
Anyway ashman,all jokes aside, its a nice build and have some questions for you, what breed of oil cooler is that, what size rims and is the swing arm standard? Buy the way, could you post some more pics please at the smaller UPLOAD to photo bucket option of 900x780, that way we see the full pic.
