Neil at Cornerspeed an official Ducati service centre has already in contact with JE Pistons on our behalf as he uses them for Pistons for the 748 to 853 conversions.

hopefully they will produce the piston kits and list them on the site as a stock item like the 900ss 944ss,
But not HC ;) :)

I bought a pair of 904cc hc pistons a few years ago when the pound was strong and got them for £150+ postage.

Hopefully that will be the case

as for buying Pistons

I had arrive yesterday a really good pair of 583 pistons and rings from a late (1999 - 2001) engine that I won on Ebay for 99p last week :)
Now to get the Class B bike built and get it running.

So far I have sold 583s to Andy Sheppard and Dallas, they seem to do OK on them. Andys was the earlier engine with 2:1 Primary and Dallas's the later engine with the 1.85 primary and Clutch Slave on the left. even my original Class B bike wasn't to bad netting me a few trophies

I was lucky last winter when i found a pair of pistons/rings and cylinders
which had only done 2k miles. (got them for £100 complete)
Phil's got my old pistons which had covered 25k road miles and a seasons racing :o
they measured well out of tolerance and were scored badly on the skirts.
But it still ran :)
Pity I didn't check the static ignition timing last winter as it's a mile out
(retarded) max retard on pickup mount/adjuster plate :(

no wonder every class B rider past me down the straights

Note to self...... check the timing you retard! :mad:

I was amazed to find out how far the as delivered Cam timing can be out from the recommeded settings when checked, so it doesn't suprise me the same can apply to the Ignition timing, may well be one of the issues with my 620, note that at Cadwell your bike Steve was one of the few that didn't pull a gap on me out of the slower corners.

Kev
I was amazed that the adjuster nuts are un touched and show no marks that
it's been adjusted.
Phil has a very good write up on his blog over on ducatisti all about cam timing etc and how to do it :)
My pulleys are unajustable but you can make offset woodruff keys according to Phil (Ghost)

I'm a little layed up at the mo after a op .........
But i will check the cam timing and let you know.

Mmmm, no answer to that one yet then Antonye???

Chris,

Discussions with tyre suppliers have started this week and at the moment we are gathering information, so that a balanced decision can be taken.

It is not expected that all of the necessary facts and information will be available till the middle of next month at the earliest, so people will have to be patient.

This is a complex area and has enourmous safety implications for riders, so of necessity something that is not to be rushed.

Chris

No problem there Chris, I was just wondering why there had been no answer to Antonyes post.



Chris:burn:

That's because there's not going to be an issue once the weight has been added to the bike
With a couple of suggestions for a minimum combined rider and Bike weight, I thought 400kg should reduce the risk of most tyres sliding about wet or dry.

Lets get this absolutely clear once and for all shall we? This alleged letter from Pirelli DOES NOT EXIST. I have spoken to Steffen Baum, Technical Director of Pirelli Racing and he is aware of the series, and is aware that such a letter was requested, but PIRELLI REFUSED TO PROVIDE SUCH A LETTER. Eddie Wright, a former Pirelli Director who is now MD of Competition Logistics, who run ALL Pirelli race efforts, ALSO confirms this letter does not exist. They have also LAUGHED at the suggestion that they would EVER have written a letter telling us we must use ZR rated tyres, then 2 years on, re write the letter to say they are no longer suitable and that we MUST use H rated tyres.....In fact, Pirelli tell me that for us to use these tyres is a pain in the **** for them, as they do not sell the H rated tyre in the UK so it DOESNT promote their product, and they ONLY bring in 60 pairs a year specifically for our series, and these are ALL sold to Holbeach.....hence the monopoly. The few that are available outside this source are grey imports..........So we have been fed a line on this one, as have Pirelli, who have been told that we as riders have INSISTED on using the tyre we do, and do not WANT to use a better spec tyre....they are bemused to say the least....Please feel free to ask him should you wish to disbelieve what I am saying. A certain member of the race committee that has just resigned has also confirmed from the DSC point of view that this letter does not exist. I think he finally got sick and tired of the bullshit that he has been fed, the way that we and Pirelli have also been fed it....

I have had tyres from a number of UK sources all of whom get them direct from Pirelli (UK).
Paul at SMD Tyres tells me that Pirelli have now passed distribution of the Diablos (H rated or otherwise) to Cambrian Tyres in Wales but that it is still a UK model and still readily available.

Not sure but wasn't it Eddie Roberts who was the former Pirelli Director.

Same here, although admittedly my last pair of tyres were purchased in 2007 (just before my big off at Castle Doom!) and they came from my local tyre depot place who had them in stock.

So from a safety point of view, we're fine to just go out on any old set of tyres now, right?

Lets go for the 100 post again with this one!

tyres are over-rated. rims is where its at

Now that is an interesting idea! I wonder how much extra performance can be wrung out of a better set of wheels?

Lol, that will open a can of worms:eek:


chris:burn:

One might suffer from being accused of it being deliberate - in order to lighten the mood and reduce the amount of invective!

However think how much weight could be saved if we allowed plastic rims.

Something like this then, even come in a variety of colours:)

Chris:burn:

Maybe we should see if Polimotor could do pistons for the Class B bikes

http://www.lolaheritage.co.uk/scrapbook/004/004.htm

Got some slugs in a tupperwarebox that'll give your can of worms a race as long as I can use Chris' wheels!


Are we at 101 yet?

I've been told that Oval wheels are best, along with stripey knee socks, large check trousers, braces and a curly wig, and a brightly coloured bowler hat with a bird inside it.
Top this lot off with a big red nose that honks when you squeeze it!

And don't even get onto the 'rimming' debate !!!!!!!!!!!!!!!!!!!!!!!LOL !

I was thinking of taking a lead from Hengist Pod out of Carry on Cleo who invented the square wheel! It apparently gave a somewhat clunky ride!

No Handbrake required though

None of my business, but the 'safety' point is a complete dead herring as baldrick would say. If you were serious about safety you wouldn't let riders risk themselves and their machines on cold tyres or road tyres in soaking wet conditions, you'd allow warmers and wets. I used to race road tyres in March in the cold and wet, but I'm older and wiser now:lol:

As for weight restrictions, please be serious:(

You should be thinking of reducing rules, not making more complexity, DD is a minefield already

WeeJohnyB

Hear Hear, a sanitised statement.

Free the Maxxis 6!!

wets & warmers
 

I rode on slicks on my 999 at cadwell the race started in the dry, It then started raining and two bikes crashed.

then it was red flagged and we were given 5 mins to change to wets.

then it stopped raining and everybody went out on slicks.

then it started raining and 2 more bikes crashed.

then it was red flagged again.

Safety isn't slicks, if its wet, wet tyres are great, if its dry, slicks are great, but inbetween is horrible!


I've just bought a set of wets, £280 (bridgestones) and I'm told if it stops raining and the track dries up abit their knackered in a couple of laps. if its raining very lightly or stop start, people use slicks because they still offer more grip/speed as long as it doesn't get too wet! :confused:

cheep racing?

With slicks you need to keep them hot, wet, hanging around and restarts all work against that.
as for wets when I raced in F600, powerbike, open and SoT I learnt to carry a set of part worn wets for those conditions where the track was wet at the start of the race but likely to be dry by the end of it.
When I had the Fireblades, i had a wet bike & a dry bike and eac had a choice of tyres. Drys & Inters for one and wets & worn wets for the other, not cheap but I had more spare cash then so it wasn't an issue and a worth while investment when entering 12 races over a weekend

and hows the slipper clutch Matt

Whatever tyre we end up using ..........................................

I have just sold my scrubs to a 600ss owner on ducatisti and need to get
whatever we use fitted asap as i cant move my 583 out of my shed :mad:

4 of the 5 of you that consider taking the **** out of serious suggestions to improve the series dont even ride or turn up at DD races, so instead of being busy cuddling up to each other and patting each other on the back, why dont some of you get off your arses and attend a few meetings, and see for yourselves the groundswell of opinion from people that wont necessarily stand up and be counted here, because believe me, carry on being such ****ers and you wont have a club before much longer. You are so far up your own arses that you cant see the problems for looking. Well dont worry, I'll get Maxxis to withdraw their offer, you stick to your guns and bury your heads in the sand, and watch when a rival sponsored series starts, which one day it is sure to do if you carry on thinking you dont need to develop and improve. I cant believe allegedly adult people see their way clear to talk such utter ******** as I have just read in this post. Why ask for suggestions for improvement when all you want to do is take the **** out of any suggestions that arent yours? Many people have left this club because of exactly this attitude, and still you cant see a need to change your attitudes....it's pathetic, it really is.
Oh yes, and if any of you ever have cause to need that non existant letter, remember that....it IS non existant.

The book is now closed and will soon be paying out on this bad boy going over 100!

a serious piont!
 

contentious yes but serious, so let loose the childish banter and leave only sensible suggestions, as people have already said there are refresh programmes for next season on hold until this issue is resolved and we would like to test with the new tyre asap. i know i would. so come on ladies and gents, stop the mud slinging and lets get on with the business at hand, please!:(

You can't and won't please all of the people all of the time.

The forum can't win, it is accused of being too serious, then not serious enough?

There is a structured process in place for the refresh/suggestion of the rules of DD for 2010, it has been clearly stated how the process will be handled.

The majority of DD'ers do not post on this forum, but many utilise the correct email process to make valid suggestions.

The organisers of DD have stated they will not be taking random suggestions from the forum.

But it remains a place for discussion, debate and **** taking, you are either in or out.

You decide to participate or not.

The peasants of DD have been revolting for years....long may it continue!!

As all serious suggestions should be submitted as layed out in accordance with the Desmo Due rules and that being the basis for this topic as noted in the very first post, then any suugestion made under this post aren't considered as offical and leave themselves open to attracting banter.

So far emails have been received that have included among others

Removal of the wording to do with ignition timing to allow it to be altered
Allowing Crank Balancing
A combined minimum weight for Bike and rider
Use of Carburetors on Class A bikes
Change to Maxxis tyres
Blue Printing of engines
Change wording to cleary ban any use of devices that change ignition timing
Don't go to Maxxis, if not Pirellis then look at Bridgestones
Use of Wets
Use of Warmers
Switch to Dunlop Alpha 10s
Open up rules on sub frame mods futher to allow for crash repairs
Do away with the control tyre and allow a tyre free for all where everyone can use what they want

In some cases there is only one suggestion with others there are two, three or four

piont taken
 

i take the hint about about being too serious and have already submitted my email suggestions.;)

Do it my way or I will take my ball home... :lol: How to make friends and influence people?

Well that's probably the final nail in the coffin for the Maxxis debate; - why would a race series want to commit its riders to a tyre that could be taken away from them at the drop of a hat because somebody did not get their way? I can see it now...."Protest that rider or I will get the offer withdrawn" :rolleyes:

Good luck guys with your ideas for next season, as has been said you are never going to please all of the people all of the time and tyres for some reason seem to be such an emotive subject, they have been for the day of conception of DD, - I still have the e-mails from March 2005....Go for Barum tyres, add a bit of fun! ;)

Ian :)

Blimey!

I don't give a monkey's ball bag what rule changes come out as long it doesn't hit my wallet, if Maxxis want to offer budget tyres and they're safe then why not let them? There are 2 tyre manufacturers in F1 and it's a battle betwen them, Otei has offered to test Maxxis out so why not let him? I'd rather take the word from a good fellow racer who'll be looking after his own arse than a marketing guy who wants to get his company noticed. If we do then change to Maxxis let those who has forked out on Pirellis (like yours truly) run them till they're done and then change. After all isn't this meant to be a way to get people racing as cheaply (not forgetting safely) as possible?
I agree with Nog about the **** taking as this is people's racing next year we're ranting about, but as long as this thread is banter and the serious stuff is discussed through the proper channels then let's extract some more urine in good humour. As for those who just talk a good race, get of your arse and show us instead.

Just waiting for the "I'll have you know I used to be......." and the "I can't race any more because........." excuse brigade to pipe up now.
As stated in my end of season report, there are sayers and there are doers, if you're a sayer then shut up and start doing before you comment.
And thanks Nog for trying to sort something. (and yes I know you shouldn't start a sentance with the word 'and')









That should stir some 5h1t.
