have started planning next years project- ok so the above may not be feasible ( didnt get any replies:puzzled:)apart from fitting the six speed cluster in the 600 gearbox and adding an oil temp guage as per the ducati performance catalogue part no 965069AAA where does the sender fit????? is it possible to plumb in an oil cooler to original 600 crankcases? and also in the ducati performance catalogue there are some variable-advance control units- do these just advance the ignition timing if so , for what purpose??higher torque? faster revving?or just moves the torque of the engine to lower revs ?

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:

NBs996
09-Feb-2005, 01:47
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

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

monstermob 998
09-Feb-2005, 07:13
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?

madmav

legal tread depth for a bike !


Bike 1mm

Here's the procedure.
Get bike out of garage.
Check tyre pressure (yes I have a digital tyre pressure gauge of my very own).
It's invariably 4 - 5 lbs down on the front and between 2 and 4 on the back.
Take it to garage (200 yards up the road)
Add air.

re-measure pressure next time I get bike out - about 5 - 7 days later.
pressure dropped again.

I have to say, I think it's something to do with the fact that I'm riding on these 208RRs. I've never had this drop in pressure on any tyre before, unless I actually had a slow puncture.

And what about the tread??? Where's you're reply on that?

Leave it till you're sober to answer because I don't want to have to struggle with some uninteligible drivel - (she can bl00dy talk! :lol:)

:sing::devil:

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!)

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:

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.

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 ..

NBs996
15-Feb-2005, 00:29
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?

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:

Nick, I had no idea the consumption could vary that wildly. To be honest, I don't notice how it alters on track days because I have all my dials taped up so don't look at mileage. But it seems that I'm about right on average riding, which enables me to plan my trip abroad in 100/120 mile pit stops. Are there any guides of Europe that tell you where to get fuel? Oh man, it's too complicated to think about. I expect I'll just pack a rucksack, book a ferry, buy a map and wing it! bouncy::bouncy::bouncy::bouncy::bouncy:

Brake lines...

Most brake lines feeding twing calipers seem to have a single line from the master cylinder splitting into 2 about half way down to feed both calipers.
Other setups, which are not so common, have 2 separate lines from the master cylinder on a double banjo.

This question is because I'm doing a twin disc conversion to the Monnie, but don't know the pro's and con's for the the different brake line configuration.

Any braking experts among us?

16-Feb-2005, 13:14
Nick the two line option from the calliper is the most common on race bikes as it only envolves banjo fittings, my 998 has a T- piece just above the bottom yoke but is not the way I would go if I was making up the hoses myself.
Some bikes do come with a splitter box that is usually cast alloy and is bolted to the bottom yoke, again this system usually only envolves banjo bolts but in this case 6 of them, the weak point of this system is that the splitter box can easily trap a bit of air that is hard to bleed out.

My preference is Two hoses from the mastercylinder fitted with a double banjo bolt that has a bleed nipple in the end, unless you use a Brembo or AP Master that has its own built in bleed nipple

16-Feb-2005, 22:58
Single vs. Dual Lines

From a hydraulics point-of-view there’s no difference. However, the two-line configuration has a longer total hose length so you’d expect that you’ll have a little more volume expansion under pressure than with the one-into-two line configuration. More expansion of the hose will give a slight springy feel to the brake lever but won’t affect stopping power. The difference is so slight that the other factors mentioned should be considered instead.

16-Feb-2005, 23:43
My choice is to always fit two lines up to the master cylinder. Some people dont like this idea for some reason, but the thing I really really like about it is gravity ! Those pesky little air bubbles will always go all the way up to your master cylinder and with most setups, they will self-bleed when you put the bike on the sidestand. I even go as far as taking the calipers off when bleeding new fluid, cos I get gravity working the bubbles out then too. The job is done so much faster, without paying stupid money for a contraption that is trying to push air downwards !
I learnt the trick from trials riding, where believe me, you get into situations where your brakes _have_ to be absolutely perfect, or you're on your ear literally ;)

What are the comparative weights of 900SS, 851, 748 and 916 engines ?

skidlids
17-Feb-2005, 00:09
Have you got some large scales handy
currently out of the bikes and available for weighing I have a 955 engine along with engines from a 600 Monster and a 748 and if my mate gets his finger out possibly would be able to weigh a 900SS engine as well
From lifting them at various times I would say they are all quite heavy, heavier than my ZXR400 engine and my R6 engine and my Fireblade engine even my TL1000 engine feel lighter than the 600 engine

phil_h
19-Feb-2005, 20:51
Hmmm ... shame oxford isnt an easier journey or I'd bring my bathroom scales over !
I'm enjoying the low-speed smoothness of the 748 so much compared to the 900SS lump in the beast that I am wondering how much heavier it would be if I put an 851 lump back into it !

NBs996
25-Feb-2005, 08:51
Simple really, it has a high content of hydrogen chloride (hydrochloric acid), which the freezing point as around -114degC.
Your battery acid will freeze well above this point though, because there's a high water content which , as we all know, freezes at 0degC.

So depending on the percentages of HCl and H2O that you have in your battery, the mixture will freeze at somewhere between -114 and 0.

Wavey discs...

The original concept of these was so that the edges of the the disc would run across the surface of the pads and shave a tiny layer off, this was supposed to stop the pads glazing. Negative effect of course was the pads didn't last very long!
I may be wrong, but I think the first team to use them was Padgetts? Kev is gonna tell me I'm wrong!

But we have them on road bikes just cos they look flash!

25-Feb-2005, 09:51
You need nice narrow tyres on snow. Big wide four x four things dont exert enough pressure on the road to cut through the snow to the road below. Look at rally cars used in snowy events. They run tyres that are only about 100mm wide.
Also most four wheel drive things dont have diff locks which makes them a bit pointless in my opinion.

Who owns Ducati (the company) these days? Or who has a controlling interest?

ali
25-Feb-2005, 12:19
Last minute question:

Lots of discussion going on about length of inlet manifolds for 600/900 2v, the theory being that the shorter manifold (on the 900) gives better top end power than the shorter. This is (in theory) because the 900 has more torque low-down, so can afford to be tuned for top end power.

My question is 'If I fit the shorter inlet manifolds to my 600, what do I use to connect the carbs to the airbox??'

I spoke to Nelly about this, and confused him greatly.:lol: He'd just fitted Mort's even-shorter manifolds to the blue beast, but couldn't remember using anything different from standard to connect the injector bodies to the airbox!

Cheers,

Ali

i might be talking b*******s but can you not do away with the air box and fit a couple of K+N filters straight on to carb intakes?
something like these ;
http://www.knfilters.com/universal/universal.htm

i appreciate that these may upset the dyno kit if you have one etc
i dont know if there is enough room to do this its too cold to have a quick look at my own bike to check but i would consider it to acheive what i think you are trying to do i have used these on several cars in the past with a bit of main jet and needle tinkering i had good results

or is this against the rules?

The most recent info I can find: Ducati Holdings Group is owned, at least 33.4%, by Texas Pacific Group (TPG), a venture capital company in the U.S.

How much of the company is public I don't know, but a quick look makes me think most of the rest is, and it's owned by find managers, etc.

Ali you could always dump the airbox and CV carbs and fit a set of nice exspensive Kiehin smoothbores.
I understand from reading the rules that to fit the shorter inlet tracts you need to cut the cross brace out of the frame.

Being as I sold my 748 track/race bike to Old Yella for just over £2k I have no intention of spending any more than that on my 600SS so that rules out getting to much done to the bike especially on the tuning front as I just sold a more powerful V-twin race bike that has been out playing with the big fish/sharks in SoT, Powerbike and Open.
I’m still going on the maxim “don’t race what you can’t afford to trash” after chucking a £4k bike in the skip at last years TT I think i'll try and restrict myself to a £2k bike this year.

Ok a last question then.....

Apart from the obvious expense - I cant help wondering why Ducati didnt make a gear driven cam train for the belt drive bikes ??? If H0nda could do it with the VFR range, couldnt Ducati - or does the Desmodromics (?) prevent this in someway?

I was just thinking about the carnage (Bikeage ???) that could be produced if a belt ever snapped :o

Sure there'd be a few miffed dealers out there if the belt didn't need changing every ten minutes! It's also worth bearing in mind that Honda can do things with mass-production engineering that Ducati can only dream about...

As an aside to this question, does anyone have a cast-iron example of belts snapping? What mileage? What damage? Which cylinder? What's the difference between a duke belt that needs changing every 12000 miles and a Honda one that lasts 85000?

I'm with skids on this one. A bike you can afford to bin has to be worth 2secs a lap!

Not that I wouldn't want a set of FCRs, but if I had some they'd be 41s and on my SL....:D

Seen the carnage of a 996 belt snapping at a Pembrey practice day a couple of years back when I guy I was often racing against decided he would try and get 4 race meetings out of his set of belts, not only did he need an expensive engine rebuild but also lost the points for 4 SoT races as the day was followed by a 2 day race meeting. Luckily the Desmo Due belts aren't under the same amount of strain as the Desmo Quattro belts but they will still need replacing at regular intervals. Luckily they are fairly cheap and easy enough to do.

Well..I remember reading a thread about a belt snapping.....

Destroyed valves and pistons.
Damaged valve gear, con-rods and barrels :o

In my question I did actually mean why didnt Ducati do the gear driven cams on something like the SL maybe, as a limited production run to make it really 'special' (with a bit more power to boot !!!)
***I think I've just created a niche market **** ------ NOT !!!

Ca-cycleworks seem to be the peeps tp talk to about FCR's on Ducatis - I've seen a few banks of 4 - 41mm FCR's for some of the Suzukis etc and wondered about splitting them in half but, it seems like a lot of problems for not much money saving.

How much of the company is public I don't know, but a quick look makes me think most of the rest is, and it's owned by find managers, etc.

Hmmm... dead right Ali, Shareholders.
Looks like TPG are the controlling partner, other shares held by the board of directors of DMH.
The rest, I wouldn't like to speculate... but you can get their investor profile from yahoo financials for the princely sum of $25!

I dare say one of the euro versions of ebay may be able to help. Tend to get quite a few race bits...;)

Cheers for the ownership info guys. I too thought it was Texas Pacific Group but a guy i work with found some info that said VAG had a large interest.

can i have one last question please?

tony rutter had some success back in the eighties/early nineties racing a 600 ducati -i believe that is what the 600SS engine was based on-- any one know what spec the bike was as regards to carbs,cams,pistons, suspension, exhaust and or any other go faster bits?----cant seem to find any info on the web

The earlier bevel drive bikes were desmo ( well, most of them anyway... ) and they used a shaft to drive the cams!
There is no reason why the cams could not be gear or bevel driven...it's just that they aren't anymore!
And of course we'd all have to go and join the DOC :lol:
Hurrah for belts!!!!!
:P:P

So, for a last minute bid for some more points before closing time...

What's the thinking between belt driven and chain driven cams?
Surely the chain drive is much more reliable right?
So why belts instead of chains?

p.s. yeah rushjob, I know we'd all have to join the 'onda owners club!

Actuallly, gears are more reliable than chains...ever heard the old joke
Knock knock...
Who's there?
Honda camchain tensioner...........
:lol: :lol: :lol:
Chains sap less power than gears,
I'd imagine belts less so still
( Lower reciprocating mass..... )
Noise levels for belts are also lower than chains or gears....
My Guzzi had a gear driven cam....what a wonderful noise that made:lol:

Sorry it's dragged on this long.

Judgement day looms so a few odd brownie points could be acquired before bed time. :P

Ah yes andy, I remember my cbr6 - took me ages to work out what that knocking noise was!

Maybe there's some thinking that the belts being external will save a bit of space in the engine (where chains need to be inside the casing for an oil bath), so the engine can be made slightly narrower and save a few more gramms?

Just thinking out loud...

Time's up. Thanks to all of you who took an interest.

And all of you who took some benefit. I know this board provides a plethora of information on a huge range of Ducati topics.

Currently in consultaiton with the other judges. Anticipated posting of results Sunday evening.
