Same Quiz, New thread
 

Where are our panelists? This chap clearly has a technical question (well, it looks like one to me, at least) and he's waiting for an answer.

The last thread is taking too long to download on my dial up so I'm starting a new one.

Get cracking, you know alls. :P:sing:

I have no idea I have a 600SS at the moment to turn into a race bike and I also had one a couple of ears ago for about a month, I've never had a 750SS so I have no idea what parts are common to each bike and which ones are not.
now I could tell a few porkies and see if anybody catches me out but that would be a bit unfair on the person asking the question.
So I will try to answer questions that I have some experience of but ones like these I can't so I am hoping somebody else will enlighten me by answering the question correctly

Ruth your loss of wind !!!

it could be the valve caps you have got on !

IE some aftermarket ones when you screw them down can catch the valve core and let air out (centrifugal force)

or it could be the rimms leaking at the Bead

or it could even be porous rims !

i would look at the valve caps first!!:cool:

mav's right about the centrifugal force making yuur valves pop out a bit... you valve caps are a secondary seal to the rubber seals inside the valve which is held down by a spring, if the spring is old and weak and the caps aren't sealing properly then the air could easily leak past.

First of all you should be checking the pressures with the same pressure guage all the time (no 2 are callibrated the same), then it might be worth spending a few pennies on some new valves... not the whole valve, but just the springy bit inside which you can get from halfords.

If you've got porous rims then that's a lot of bad luck and a lot of money to replace. 99% sure that it's either the valve internals leaking, or you're not checking the pressures correctly. Try doing the pressures clinically, i.e. at the same time of day at the same abient air temp, with the same guage, after they bike's been sitting overnight... and if that still shows a significant drop then replace the valve seals.

p.s. take no notice of this post because i'm a little under the influence and don't even know how i managed to turn the pooter on, let alone think about answering your question! T'was a good kareoke night tho :D

n

As for monstermob's question - i haven't been ignoring you, I just aint got a fekin clue mate.
Sorry.

Ruth,i had a similar problem on a quattro ur a few years back,shortly after fitting new tyres- what i done was brush some diluted fairy liquid around the rims and valves when the tyres were warm(when the pressure had increased slightly) the very slow trail of bubbles revealed that it was in fact leaky rims- i took the car back to tyre shop and they removed tyres and brushed some sort of rubber paint on the inside if the rims just where the beads of the tyre sit and this cured the problem

As for the tyre wear have a quick look at your tyre s and see if there is a tread wear indicator (a raised bit actually inside the tread ) without the aid of pictures and lengthy descriptions i cant be more detailed sorry but if you pop into your local tyre shop they'll show you what it is, car tyres have them as well - no need for tools but i think the legal tread depth is still 3mm-might be wrong?

legal tread depth for a bike !


Bike 1mm

Hgv 1mm

car 1.6 mm

;)

Tyre Pressure (from the other thread)
 

Hi Ruth
Have you measured the pressures with your digital gauge at the garage, immediately after you have re-inflated the tyres? Check what your gauge says against the garage pump's gauge's reading. There can be a big difference!
:eureka: (maybe!)

Question..... why do beans make you fart :puzzled::puzzled:

Because you are dave, a right dirty muckie puckie

Gas leak pants :frog::frog::frog:

ok -
the 600 and 750 share crankcases, and are so close to the original 1980 pantah cases its not true !
the 900 and above are newer cases, but if you look beyond the plumbing on an ottovalvole you will clearly see that the crankcases are really the same as the old 1990 air-cooled 900 ones.
So - you can fit the 750's hydraulic clutch setup on a 580 for example.
You can also swap other bits like cranks and gearboxes too, but because some machining is done (for things like the barrel spigot) you may have to a little bit more than 'just drop it in' :D when moving up in capacity, but the other way round should be almost a doddle :saint:
Adding an oil coolers is a simple plumbing exercise anyway, but if you are only going to run for a half a dozen laps ... do you really need to add all that weight :D


btw
given the lack of interest in my FE for sale ... I'm even thinking of picking up a 580 engine (£100 ?) and bunging that into the FE :saint::o:eureka:

Well done Phil_h for answering that man's question. :D (at least I think you did, but what do I know?)

Skidlids, well done for fessing up to knowing nothing about it. Does you credit! :roll:

Thanks for all the replies on the tyre pressure and tread thing. Pretty comprehensive and a great help. I should be able to get that problem sorted now. Whether I do or not, is another matter, of course. :D:lol:

Phil_h
thanks for the info so my best route is to keep the 600 cases drop in the six speed cluster and then plumb in the oil cooler into the feed and return points on the front of the left case( which i have just found- its amazing what you can find when you get on your hands and knees ..doh) feel a right dipstick!!! -- not racing it phil, just like changing things!!
may even go as far big bore kit and race cams tho;)

FE ?? what does FE stand for?

Still part of a question unanswered here?

Can anyone help the man?

I can see where this might lead. Let's keep it clean, please boys. :lol::lol:

Final Edition ( 900SSFE )

Final Edition.


Damn, them coppers are quick!

:smug:

Again just to show I don't know everything

I would like to know the weight Bias of a standard 999 and that of a Factory race bike, what is the percentage split between front and back.

Info needed for a future project I am planing

thanks-- i am now enlightened fully!!!!!

Kev
Normally, it's about 50-50, but becoming 0-100 on the Mountain at Cadwell :frog:

Seriously, I would like to know the answer to this as well - not that I'd do anything special with the info, I'd just like to know.

quick question- what is the connection between Ducati and Senna?I take it,it is the great late Ayrton Senna?----well ruth did say the questions you were afraid to ask!!!!have been trying to work it out all day--and if any body says tut tut shame on you i,ll .........

Does the Classic Ducati gets its power from being an L twin or would it be the same as just any twin?

I understand it was was a fund raising effort for the Senna Foundation, a charity set up be Ayrton's family.
The 916 Senna bikes were sold at a premium to donate some of the profits.

Don't know what interest Ducati have in Mr Senna tho.

I understand the L (90 degree) twin has excellentprimary and secondry balance forces that do not need balance shafts that rob power to smooth out the engines vibrations, I think this was well demonstrated with the Supermono where dispite a CC shortage against some of its rivals it was still the quicker bike, yes I know it wasn't actually a twin but the dummy rod setup where the rear cylinder would be certainly gave it certain twin characteristics where as the bigger cc singles had to give up power to balancing systems.

Excellent answer Kev. I can tell it's excellent 'cos I don't understand a word of it. :lol::lol:

Sorry to hear of your bike troubles earlier today, I blame Fordie he's a bad influence even on tyres.
If you had made it I could have answered some of those questions you must be storing up with one easy answer.

"Look there's Nelly over there go and ask him he will explain it to you." :frog:

BUMP

Bump. that's the last time I'm bumping it. If it dies a death, so be it. I just think for £125 odd prize it could have made it to the end of the month.

:(

Sorry if I sound a bit grumpy. Didn't get any Valentine's cards - NBS - no champagne and roses. What happened to the good old days of bribes and corruption? ;)

[Edited on 14-2-2005 by Redruth]

But Ruthie baby, no amount of champagne and roses could show how much I really love you!

Did somebody have a question tonight?

Nick, what colour scheme will look best and go fastest in Desmo Due?

Look best? Mine. Definately mine.

Go fastest? Sadly, that's a different question!

Ok. I have a quite trivial question. What's the best mileage anyone has achieved from a 996 Ducati petrol tank? Someone posted something like this today, but this is for the quiz. Mine's a touring question really. I'm planning to go touring in August. The best I've got from my tank - who knows what the capacity of that is, about £9.50's basic unleaded max, I can ride for 118 miles before panicking about finding a petrol station.

Bearing in mind the riding will be steady in built up areas and balls out (obviously metaphoric in my case) in the twisty mountain bits ..

Depends on a lot of things of course. Such as fuelling setup, weight, cruising on the motorway or raggin' it round a track...

My bestest fuel figure was on the way back from Cornerspeed last summer. It was a motorway cruise at about 90mph from one fill-up to the next, and the light came on at 145 miles.

Worst was a Silverstone, where the light came on at 45 miles.

My average road riding, which is mostly very sensible and within the law, usually falls somewhere between 100 and 120 miles 'til the light comes on.

Tank capacity on a 996 is 17 litres, the light comes on with around 4 litres to go.

Is that any help?

[Edited on 15-2-2005 by NBs996]

Sorry I haven't owned or ridden a 996 so have no idea what the answer would be even for one on standard gearing.

Still nobody has answered my question about the weight Bias, I have one half of the answer but I dont know which half, I have a percentage split but uncertain if it is the race bike or the road bike.
Best I borrow somebody's 999 or 749 (Chippy) and find out what the standard road bike is, then I could move onto a 999R (Everton) and see how alloy subframe and lighter Termi exhaust effect things.
Then I will be able to answer my own question which I think should make me the winner :frog:

just thought of another question or is it 2 questions

Who would be interested in buying Red M600 Petrol tank off me with a dent in it but is still very suitable for track use
And who would be interested in a M600 swingarm with the suspension loop

Sorry kev, the weight bias question is beyond even me!
For the road bike it's usually in the brochure isn't it?, but that doesn't seem to be availabe yet, at least not on ducati.com

Nick you haven't even had a answer to your question about General Failure, what I can tell you about him is that he will soon be leaving your hard drive alone and will reappear on May 1st at Cadwells Woodland circuit where he will access your electrics and slow down your bike just as he does your hard drive. :frog:

F**ker!

You'd better hope he does!
