@Old codger:

" It took next million races to get aluminium chassis. Another million to get aluminium non-stressed chassis. Few million more to get complete aluminium bike with aluminium swing-arm. "

" I've told you a million times....don't exaggerate "

Now Now, Don't be so sarcastic.

Thanks Cammyspop

With those sealing rules I can't think of a single part that would affect power delivery that can be changed, unless they've found a sly way around it then all of the following are ruled out - valve timing, compression ratio, bore/stroke ratio, crank weight, rod length, chamber shape. The only thing I can get my head around is it might be possible to change valve lift.

If we think better maybe will see that Ducati are doing what they can at the momente.. Because we forget that they have engine Rules and limit engines to used.. They can t just bring one completed engine just like that.. thinghs have to be very study, with very carefull, the last thing we whant for this year is Engines failures, realiabilaty problems that will put an end to the standings 2012 champion.. I agree the most importante parte to change is the ECU and other electronics step by step they will get there.. If they rush the program it can be wrost that they are now.. Maybe its better for we all chillout and give this guys a breack to make there job..

Given the fuel pressure limits in the rules, it is probably dealing with fuel injector distances from the intake valve, throttle body sizes, and staged injectors. Burgess alluded to the staged injectors, there are probably smaller injectors for the low rpm and low throttle openings that allow easier smaller atomized fuel amounts to make it into the engine at perfect ratios and driveability style responses, and then a farther stepped out injector set for the massive horsepower required for the wide open throttle.

Why is Ducati so afraid of the engine rule? Just unload a powerhouse engine, and if it fails, and they run out of engines, the rules will be changed on the fly as they always are.

Do you think the show is more concerned with sponsorship/money, or the sport's integrity? It's already a gong show, so imagine what would happen if Ducati ran out of engines with 4 or 5 rounds to go - would they keep the Ducatis and VR off the grid? Of course not. Just as they folded at the knees to get Marquez onto the Repsol ride, they will do everything possible to keep their bread & butter warm.

Tis the sport.

kerkz, no manufacturer wants to risk harming it's reputation by having engine failures in public, probably more so when they're already under performing. That's why failures are always claimed to be electrical.

However the penalty for exceeding the limit is only a pit lane start which they may use in order to try something new, they've done it before.
