The Desmo Due Weigh In

[skidlids]

As we will have lots of free time to kill at Donington I am hoping to bring my two sets of scales along and weigh as many bikes as possible I think we have 34 entered at present. The forms are printed and the ramps are made, maybe have to get some new batteries to be on the safe side

On Saturday the scrutineering bay will be a busy area and then we will be on track at 11am and then later in the afternoon so I am proposing we try and arrange it for either Sunday Morning or Sunday Lunchtime (what would people prefer) and possibly do it in 3 groups

Class B odd numbers
Class B even numbers
Class A - All

Normally weighing of bikes to police the series would take part when a Parc Ferme is held after a race and then bikes directed to the weigh area.

I intend for this to be more of an eye opener so anybody whose bike is under weight can address the situation and those with bikes over weight can look to see where they can make improvements.

I also intend to bring 3 bottles of Plonk with me as prizes, just need to rember to put them in the van with everything else.
One for the lightest legal bike in each class (must have at least 2 litres of fuel in the tank) and one for the Heaviest overall.

As my bike has no chance of being the lightest in class A I was thinking of filling the tank to the brim and see if I can make it the heaviest

Kev,

I take it that yo will not be weighing the bikes with the rider on then?

Chris

[Lily]

I reckon I could have been in with a chance for heaviest as there has hardly been anything removed from mine apart from the required stuff.

[skidlids]

Lily that just makes your results that much more impressive,

My bike needs to shed a few more Kilos and the rider a few stone, wouldn't do me any harm in the acceleration and stoping stakes

Maybe by the end of the season we will have a feeling for who had what in the way of power to weight ratios

Kev,

Certainly not as the Class A lightest combination is a dead cert, it'll be the skinny guy on No.34 :)

I think Scooter was in with a good chance in Class B but has had to withdraw, he tells us its something to do with strengthening frames but maybe he just couldn't find any lead to get his up to the required weight, He's nothing but a lightweight :)

[Tonio600]

Anytime on Friday, Saturday or Sunday will work for me.

So much time to kill that I'm thinking about having a crash or 2 to keep me busy :lol:

Thanks so much for your involvement Kev, you are one of the greatest assets of this series.

[Tonio600]

And btw, I do hope my bike is as light as I've tried to make it. Look forward to getting some figures :D

I used the BSI weights at work to check them and carry out a direct comparison with one of the sets of calibrated scales at work, which are checked not by lloyds but E.H.Oakley to UKAS standards, which I have to make sure gets done as one of my roles is the Calibrated Equipment officer responsible for maintaining a calibrated equipment register that is Audited several times a year by the likes of the BSI and the FDA.

I would suggest a crash at Redgate as I've seen you practice that one and you do it quite well :lol:

Thought you would have that coverd Kev, can you get our bathroom ones checked my misses recons they weigh at least 5lbs heavy:lol: :lol:

[skidlids]

Thats what I thought about my Kern ones when I got them and weighed myself, sadly the bu99ers don't lie, they are very accurate less than 1% error over the range tested.
Mind you they do cost a bit more than your average bathroom scales

Yes Phil I can bring them to Mallory






















On the 21st of June :p

[trouty]

my bike weighs the same as before, but i weigh 2 stones more since this time last season

[phillc]

I thought you might say something like that!

Maybe I'll magically happen to have a bike in the back of my van when I return your headers ;)

[NBs996]

Phil, there's a weighscale in the scrute bay at Mallory.

Phil, there's a weighscale in the scrute bay at Mallory.

I did not know that! Thanks for the tip.

[Ghost]

I took mine into work last week to weigh it, so it will be interesting to see how the load cells compare. A light battery and Harriets alum tank I may just make minimum.
Have you got ramps both sides Kev so it can roll on, then roll off, for quickness of getting the punters through.

[skidlids]

Have you got ramps both sides Kev so it can roll on, then roll off, for quickness of getting the punters through.

Certainly have Phil, picked them up at lunchtime today
20" ramp each end
44" deck in the middle
and scales that are 12" by 12 1/2"
So ideally suited to a wheel base of 56"

Still some work I would like to do like build a mains to 9v supply into the underside of the deck for powering the scales.
When its finished everything should pack inside the 44" X 13" Deck section with the 20" X 12 1/2" ramps acting as cobers to protect the scales, but that will take time, if I'm lucky I may get the carrying handle fitted before the weekend.

I use to weigh my specials with a load cell at work, I think the 10 Ton crane was a bit over kill though, although it was useful for ploting the rising rate curve after removing the spring from the shock and learning how different shock lengths put you into different parts of the curve

[Ghost]

Brilliant stuff look forward to seeing it. I had 1kg difference front to back split so very neutral, untill I get on it.

[injected]

I am proposing we try and arrange it for either Sunday Morning or Sunday Lunchtime (what would people prefer)

Kev, fwiw I'd prefer Saturday after qual, as Sunday I will be away from the track with family until our evening race.

[skidlids]

Guy, we will have to see how Saturday goes, with changes o the bike and not having raced the GP circuit I will probably be working on the bike after Qually, possibly changing gearing and suspension setup, but may be still have enough time to weigh a couple of bikes.
Ideally would like to do it in the Scrutineering bay and only really want to set up once but if the part of the paddock I end up in allows the odd bike to be checked it may be possible to do a couple Saturday

[trouty]

hows does this work then? one wheel on 1 scales, one wheel on other scales and add the 2 figures together?

[antonye]

hows does this work then? one wheel on 1 scales, one wheel on other scales and add the 2 figures together?

Basically, yes.

If you think about it, you can't have the same weight on two scales at the same time ... it doesn't magically appear from nowhere and disappear once you take the bike off. It's the same principle that two guys lifting a heavy box makes it easier than one guy on his own!

Mark borrowed a set of car scales from work once and we measured mine on it to see what the weight bias was like with a plan to adjusting the suspension to see how it changed the bias.

I'll see if I can dig the pic out...

[antonye]

Here we go...

[Ray]

Corner weight scales........hmmm you can have hours of endless fun messing up suspension settings with them. Usually done with the driver etc on board

Not seen much overt measurement of similar techniques (with the obvious differences due to one pair of wheels less!!) in bike racing?

Maybe front rear weight bias tuning with the rider on board is done behind closed garage doors?

Ray

[skidlids]

MOT stations do it slightly different as in they only use one set of scales, these are usually set into the floor so that they are the same height as the floor. Then they wheel the front wheel on take a reading then the rear wheel and take a second reading and them add them together.
When using a single set of scales it is important to have them level with the surface the other wheel is sat on other wise you could be adding a bias to the process, if the scales are set lower then the bike will read over its true weight and if they are set higher it will come in lighter than it really is.

A set of scale under each wheel eliminates this chance of error.
Using two scales dead flat will also give you the weight bias of the bike and if you raise one set a known height above the other the figures can be used to calculate the bikes centre of gravity (CoG)

Only in the X direction the Z direction is quite complex.

[skidlids]

Thanks to everybody that took part
There was certainly a wide range of bike weights, 7 Class A bikes were weighed long with 20 Class B bikes, two classics, a 1098 and Sam West's M600 standard road bike.
Class A ranged from 183kg down to 156.1kg with Steve41 taking the bottle of bubbly for the lightest.
Class B ranged from 186.7kg down to 157.6kg, with Dallas having the lightest bike in class and Rosco572 taking the prize for heaviest overall.

Other bikes weighed

Sam's 600 Monster road bike 187.6kg
1098 race bike 170kg
Classic Lansdowne Racer 138.8kg


After the weigh in I stuck my bike on the Dyno (at a cost of £25) where it recorded all of 55bhp and with its weight of 173kg I have quite a lot of work to do if I ever want it to be a competitive

[injected]

Thanks for doing that Kev - any chance you could publish the list to serve as a snapshot of where bikes started the season? If not, can you PM me my bike's weight for my records? I remember it was heavy, but not HOW heavy!

[skidlids]

Hi Guy, it was good to meet you at last and you were riding well, which made it harder for me to pass you as I worked my way through the field from my 27th place on the grid.

Weights
if people are happy to have the weighs of their bikes known add your name to the list and I will fill in the weight, also let me know if you would like the splt front & rear, I have been asked in certain quarters not to just publish a spread sheet with the results.

No record was made of any fuel levels so only you know what you had in the tank at the time of the weigh in.

skidlids Fr 86 Rr 87 Total = 173kg
Injected Total = 167.1kg

[NBs996]

I'll leave it to Craig if he wants it published, but OMFG, how did I manage any decent results with such a porker of a bike!
Some carbon fibre on order I think...

If that will remove 13kgs before a race I'd be worried :p

[Dominic Clegg]

I didnt think my bike was to bad

and then I stood on the on them and realised I was giving over 70Kg it total to harriet

[gordonparker]

Cleggy, you will have to go on Ruth's diet !!!!!

"I stood on the on them and realised I was giving over 70Kg it total to harriet"

Insist she takes a pillion !!!!! that will help

[trouty]

this is one of my biggest concerns, should i decide to enter a race at sometime... the leathers i bought last season, that were marginally too big, i cannot fit into now. I'm actually 2.5 stone heavier now than i was at the first race last season!

[Gbyte666]

Kev, you can put my bikes wheight up if you want.

Craig :)

[Robinashman]

Add mine to the dieters list please

[antonye]

Can I just say that this thread has been really interesting and just wanted to say thanks to Kev for setting this up - it's a brilliant way of helping the other DD riders in the paddock (especially new riders) to see if they can make improvements and to give them something to aim for with the lightest bike out there, as well as being a very informal way of policing the minimum weight rule.

Well done chaps!

[Dominic Clegg]

Happy for my bike weight to go up

[DRR007]

You can add mine to the list aswell kev. And anyone who can offer any advice to get mine down from 180kg to 150kg would be appreciated.

Kev,

Good to meet you and all the rest of the guys.

No problems in listing weight of bike, all credit needs to go to Rattler. For the record the bike had a heavier tank than when Rattler run it, plastic monster one, and about 6 litres of fuel in it at the time.

I think his consultation fee's could be a bit hefty thou!!!

See you all at Snetterton with a gearbox that selects gears!!!!!

Cheers Steve

Remove the amount of wood from under your seat, there's half a seventies sideboard under there, could have sold it at the sunday market :D :D
You got a mini bar under there? :cool:
(Plus we probably put 10kg of stickers on, on Sat morning :rolleyes: )

I did get quite obsessed about reducing her weight its true. I was fortunate enough to be able to strip the bike right down and build her up from scratch and was able to remove anything that wasn't needed.

Some ideas:
- go through the bike and get rid of parts you don't need.
- Only use steel bolts if its load bearing otherwise use plastic bolts or cable ties.
- Do you need to fit washers? (these obviously spread the load in certain places), or can you just use loctite?
- use cable-ties to secure parts to frame (dump mounting brackets)
- Do you need a battery box?
- Do you need a rear hugger, a chain guard, plastic shields, etc?
- fit a steel tank
- Make sure you've got very light clipon bars
- Only fit a nose and belly fairing, and make those minimal
- don't fit crash bungs, what do you save?
- use really light faring brackets and make them as small as possible
- any bolt threads that go through a nut (and protrude through) are not needed - cut the ends off - loctite.
- dump the airfilter

For the seriously commited (all of us!!)
- get a 2-1 exhaust and get as much Ti in it as you can.
- use a 600SS frame (I didn't), these are the lightest frame eligible in DD.
- use a single disk/caliper
- make sure you just carry enough fuel to get through the race, measure and calibrate (but you do need 2ltrs at the end of the race for ACU rules though).
- get light leathers, helmet (X-lite?) etc...

- you could remove all paint from the wheels and frame too.... more weight to save!!

Finally, before you race, cut your nails, pluck your eyebrows, take a dump, blow your nose and have a w**k,

Enjoy.

Tim you did gret job on yout old bike and its credit to you, Steve has a plastic tnk fitted at the moment (borrowed) as he couldn't get on with the taller SS Tank so it could have weighed less when you raced it.

As for the removal of paint from the fram, does sliding it along the track and into a gravel trap do a good job or would taking it to a proper sand blasting place be better :)

You get it to 150kg for Class B and we'll have to find you some lead, about 4kg worth.

My bike weighed 173kg but by laps 9 and 10 of the second race it felt alot more.
I already have an alloy arm to fit and will be looking at fitting some lighter silencers, would much prefer a good 2 into 1 but they cost.

A lot of weight can be removed without going mad on Titnium, etc.
Dallas's bike has a standard Steel SS swingarm and a standard tank,
I know I could shave a bit more weight off it without going for n Alloy arm, alloy tank or later typrrear wheel, but that would put it close to the 154kg limit at the end of a race with just 2 ltrs of fuel in it


Tomorrow I'm back at work and the spread sheet is on my office PC so I'll enter the details of those that have given the OK to do so and put it up.

Here's some food for thought

M620/M600(1999 -2001) forks and SS top yoke = 8.7kg
Ti race can = 1.5kg
early SS frame (standard) = 10.4kg
Alloy arm = 4.1kg (I think hat included the rear spindle)
Carbon Cans = 1.7kg ea
Link pipe for above 0.6kg
WP Emulsion shock = 2.6kg
later type rear wheel, disc & Diablo = 13.2kg

I'll way some other bits when I have some spare time
like standard SS bars, alloy clip-ons, fairng brackets etc

[SixtyTwo]

No thank you!! and i'm sure that the ladies amonst us would also like that kept a closely guarded secret!! To be divulged to only my doctor or undertaker whichever i meet first!!!!!

[rossco572]

As a result of winning the weigh in, my enforced weight loss programme for the bike has begun, off went the stock rear shock and on went the ohlins that was on my perfect keep forever 900ss called duchess, also her carbon SL seat unit. had to find stick on number boards for that as it has a wonderful Foggy #1 in carbon showing through the paint work and i don't want to damage that. I'm really fed up that i could not for the life of me, find anywhere that stocked Fablon in plain yellow. eventually got these motox ones from a place in portsmouth called dirtbikebitz.com
i've also attacked the bike with a drill in an effort to get of excess metalwork, i am using a few probolt bits as well. this weekend i am going to a mates in cowley who is a bit of a wizz with a welder and we will try and convert the pipes from 2-2, into something like ghost has on his bike, sorry phil hope you haven't patented the idea yet and cheers for the insiration.!!

Don't go trashing a CF seat unit. It's only a race bike. I've got a white unpainted Ricambi Weiss 916 style seat unit with slight crash damage but usable. It's meant to fit the SS so should just go straight on. You can have it for free. I've also got some yellow fablon - correct RAL code too.

[Otei]

Are we having a weigh in at Snett? As I'm quietly confident of a win.

Might as well get it in the paddock as I've no chance out on the track. :D

[skidlids]

I will NOT be bringing my scales and ramps to Snetterton, its the irst time using the new van and I'm still not sure where all the essential bits and pieces are going to go let alone the extras.
Also I'll be concentrating on dialing the bike in to try and get the best from it.
But I am interested in checking out your alloy tank Phil :)
