Team Velocette at Bonneville 2011...progress to date....

Team Velocette.... is a group led by Stuart Hooper from Brisbane, Queensland, Australia, ably supported by his wife Marsha and close friends Keith and Colleen Canning.


See their website...
http://www.worldsfastestvelocette.com/
Their aim after purchasing a Velocette Viper Clubman several years back was to modify it to add to the Velocette records the major one that still stands today after being set in March 1961...100mph for 24 hours.
In this case their record was to be the worlds fastest Velocette.
This was always considered to be held by Bert Munroe of New Zealand, with his 1930's MSS special attaining 132.35mph in 1971.
Bert of course is now long dead.
Stuart altered his engine to over 700cc, built a special streamlining and a longer swinging arm and has visited Lake Gairdner in South Australia on several occasions, the last earlier this year was washed out due to severe rain conditions in Northern Queensland draining into the salt lakes in Central Australia.
Stuart's current highest with the bike is 139.001mph.
See my earlier blog....

Bonneville was always a goal for the team....it is the mecca for record breakers, even though the available strip has shortened over the years due to salt mining.
He visited Bonneville in 2010 as a reconnaissance and the decision was made to travel from Australia to Bonneville to take in two landracing meeting in late August early September. 
A special crate was made for the bike with a total of two engines and gearboxes included and this was airfreighted to Salt Lake City.
They are currently at the first meeting and on the limited information I have their highest speed to Tuesday 30th was 147.485mph, although the best I could find on some printed sheets on a blog was 146.351mph

The team shelter from the heat....


The altitude of Bonneville is around 4200' above sea level so the UV is a problem. Usually the temperatures are in the 40 deg. Celsius plus range.
This meant an "educated guess" for the initial carburation setting from the sea level settings in Australia.
The number of runs in a day a Bonneville are limited due to the number of entries, so getting the best set-up can be frustrating.
When you set a record the bike goes into an impound area until the following run. Then the average speed of both these runs are taken and this forms your speed.
So a run in the cool of the early morning can be quick and the following run is often at a higher temperature later in the day often affecting the speed.
I went to Bonneville in 2004 and came away with a different outlook on the effort the people who run bikes and cars.
Glib statements that " a good 500 in a fairing could easily so that" etc don't hold up to scrutiny.
If it was easy others would have done it.
That said I was amazed in 2004 when a cigar shaped 125cc Aprilia engined streamliner did over 140mph...
Paul d'Orleans, The Vintagent, gives a valid explanation on his first blog on this years Bonneville, titled "Song of the Salt"...
See....
http://thevintagent.blogspot.com/2011/09/song-of-salt.html
He says...



"....The salt is also a terrible place to go fast. Yes it is generally packed firm on a good year, although on a bad year even the scraped-smooth racing lines will have soft spots hungry for your speed. Packed salt gives poor traction, being greasy and slick, with loose bits scattered over the top, and applying power is a delicate business. Plenty of powerful machines simply cannot put all their horsepower through the wheels, and calculating wheel-spin into rpm/speed readings is a fine art. Typically estimated at 10% of your wheel rotation, what this means is you're doing a white burnout all the way down the line. A too-rapid course correction, say after a gust of wind, could well have you spinning off course, or far worse. Braking is a bad idea too, for the same reason; what you are riding on is best thought of as salted ice. Flat yes, fairly smooth (but pretty bumpy in the pilot's seat), slippery and treacherous for the very people who cannot keep away; acolytes of the cult of Speed..."


Following are some pics from Brisbane early August  as they finalised the packing etc.


Good Luck Team Velocette...we all hope for the magic 150mph for you...!






The bike in its shipping container...
Stop press....
Seems the weather on Wed. 31st after 1pm was not conducive to running on the salt.
No news if the Velocette got a run in.....
The reports put it at 24mph plus from the SSW with predicted winds of 40mph and they don't run at wind speeds over 12mph or some figure like that....
Hope for Thursday 1st...
Two pics from my trip to Bonneville Salt Flats in 2004 which assist in giving a sense of the scene.

K100..BMW Motometer instruments .....the German motorcycle industry goes electronic for its instruments....

With the introduction of the K series 4 cylinder 1000cc BMW motorcycle in 1983 came the first total use of electronic instruments for BMW motorcycles and it wasn't without its problems.
Motometer continued as the instrument supplier for the motorcycle side of BMW and a new large binnacle with speedometer on the left, tachometer on the right and a liquid crystal display quartz clock in the middle.
Left click on the illustrations to enlarge them....
BMW K series....


The instrument binnacle and the accessory instrument.
Exploded parts list drawing...


Speedometer details....
Tachometer detail....
Gearchange indicator and trip odometer and reset detail....


Pages from DQs somewhat scribbly and cryptic workbooks with information on connecting test  and calibrating equipment to the K100 instruments and the figures to calibrate it...
so calibration figures for the speedometer are....
49.7cycles/second (hertz) = 60kph
66 cps(hertz)                           =80kph
82.1 cps(hertz)                       =100kph
97.9cps(hertz)                       =120kph
113.4cps(hertz)                     =140kph
128.7cps(hertz)                     =160kph
The rear wheel had a metal disc with "teeth" on it that a hall effect pickup in the final drive was set near and detected the passing of the sheet metal "teeth"...the speedometer then displayed this as kph or mph and drove an odometer by a form of servo motor.
The instrument binnacle suffered from mild corrosion on internal terminals such that the signal would be lost and the speedometer stop working. 
A frustrating instrument at best....
The LCD display on the clock and the gearchange indicator would, with time and vibration, segment to a black blob appearing visually and masking any reading.
Once Motometer stopped the supply of parts in the early 1990's it became almost impossible to repair....

Like many of the trade house in Britain and elsewhere prior to about 1950, Ferodo the brake, clutch and friction lining people put our a rather extravagant advertising booklet on the successes using their produces....
The titled it Ferodo Record Braking....
(an apt pun in the title on the word "braking"....)
So lets look at the 1938 edition in it's entirety....although as the first 19 pages are devoted to the automotive successes and I'm predominately a  motorcyclist, I'll cover those two pages at a time, with the motorcycle stuff a page at a time....
As usual for my blog...left click on the images to enlarge.....
Where are these available? Guess a swap meeting, sometimes on Ebay and on the elusive book auctions.....
I'd suggest you'd be paying up to 50 quid for a good copy.....
