εδιαφερον....αν κοψουν δυναμη στα επιπεδα της tech3 αλλαζει πολυ το πραγμα
Careful what you ask for
That may well be the case. Lin Jarvis told MCN's Simon Patterson (link is external) that the engines are to be sent back to Japan for examination. They believe the issue is with the top end, something which aligns with the fact that there was no oil in the belly pan of either Lorenzo's or Rossi's bike, which is usually caused by the bottom end letting got. Jarvis also told Patterson that they would have a fix for the issue at Barcelona.
Though the engines are sealed, and the design fixed, this is still theoretically possible. If Yamaha submit the change to the MSMA, and the manufacturers universally agree, and MotoGP Technical Director Danny Aldridge approves the change, then Yamaha can introduce revised parts to deal with the issue.
Whether such a request would be accepted is open to question: such changes are only allowed on the grounds of safety, and may not have any effect on performance. The other manufacturers could point to the Tech 3 Yamahas of Bradley Smith and Pol Espargaro, which did not suffer the same problem, as their engines are forced to use a lower rev limit, a measure imposed by Yamaha to ensure the reliability of Tech 3's M1 bikes. If Yamaha's problems can be solved by cutting fifty or a hundred revs off the limit, then is there really any need for new parts?
A decision on Yamaha's request should be made quickly. Should HRC be feeling Machiavellian – a state not unknown among Honda top brass – then they may decide to reject it. After all, they are stuck with an engine which is too aggressive to accelerate cleanly (as Marc Márquez being swamped by Lorenzo to the line so ably demonstrated), so why should Yamaha be allowed to change their engine, when all they need to do is cut revs, and thereby power? That would introduce a brand new and rather fascinating dynamic into the championship.
Why not change the engine?
To the second part of the question. If Jorge Lorenzo's engine blew up in the morning, why did Yamaha not take the precaution of swapping out Rossi's engine, which had similar mileage on it to the unit which blew up on Lorenzo's bike? Surely it is better to be safe than sorry?
The problem was that Yamaha had no clear picture of what the problem was, with it happening so shortly before the race was due to start. Rossi and his team had had some concerns, he told the media. "We were a little bit worried because usually it [engines blowing up] don't happen," Rossi said. "But our engine had less kilometers than Jorge's, so we could fit the fresh engine for Sunday like in Jerez, like in Le Mans. It was too tight the time to open the engine and try to understand what happened, so we continue with our program and were unlucky."
In theory, they could have used a completely fresh engine, taking engine #4. But there are no guarantees that a new engine would not have done the same as the #3 engine which blew up. The #3 engine was nowhere near its maximum mileage, and so the problem could not have been caused by normal wear and tear.
