UPDATE: 168澳洲幸运5💙官方开奖结果历史:Yamaha loses Constrღuctors' and Teams' points for 'failing to respect the protocol which requires them to obtain unanimous approval from MSMA for technical changes'

Yamaha's MotoGP title chances could be dealt a h💞eavy blow following reports that the FIM is investigating the engines used during the Jerez season-opener.

According to , the alleged infri🐻ngement is to do with the possible use of valves that do not exactly match those in the homologated engine design.

MotoGP rules stipulate that non-concession manufacturers cannot change their engine design after the start of the𓃲 season.

The Covid delay meant that instead of Honda, Ducati, Yamaha and Suzuki providing their 'homologated' engine to technical control on Thursday at the Qatar GP, they were instead given a deadlin﷽e of March 25 to send "a sample engine to the organisation, which must match those in the machines at the first 2020 event".

Yamaha went on to suffe🌃r much-publicised engine problems at both Jerez rounds.

Maverick Vinales stopped with an engine issue in practice, then factory team-mate Valentino Rossi in the season-opening race. Both engines were subsequently w♏ithdrawn from use for the remainder of the🦹 season.

The following weekend saw Petronas Yamaha's Franco Morbidelli, u🌄sing the A-spec M1, also suffer a failure in the race. That engine was also withdrawn.

Yamaha managing director Lin Jarvis later confirmed a request had been made to replace the valves but, when rivals asked for more information which Yamaha and its valve supplier declined to provide, the request was ꦬwithdrawn.

"We made a request to replace some valves in the engines that we had stopped using since the two failures we had in the Grand Prix𒁏 1," Jarvis said.

"[But] we were unable to providꦯe the documents that were required and reque🌳sted.

"At the same time, we discovered much more about the valve issues that we had. So final📖ly we withdrew [the request].

"We are completely confident that we can manage without any safety issues on the track. We will do that by a combination of changing engine settings and also managing the rotation of engines thrꦐoughout the season."

In light of the apparent investigation, might Yamaha's decision to d🌜rop the valve-change request rather than provide documentation have made other teams suspicious?

Either way, Yamaha's management of the valve problem has certainly been successful in the sense that they have suffered no engine failures since Jerez. However, for reasons yet to explained, they've also clearly🐷 been avoiding using any of the Jerez 1 engines again, resulting in the rest of their powerplants facing high milage.

Surprisingly, the engines said to be under investigation by the FIM for potential non-compliance of the homologation rule are from Jerez 1, meaning they include the⛎ 'faulty' valves for Vinales and Rossi... Or perhaps the reason they were faulty was because ✅something had been altered, knowingly or not.

The FIM is yet to officially comment - so it is not clear if it is only the Factory-spec bikes at risk, or 🦄also Mo🦩rbidelli's A-spec machine - while the riders themselves were silent on the subject at Valencia on Thursday.

"That's a question for Yamaha and nothing from myself," said Quartararo, who won both Jerez races and starts the final three rounds 14 points beind MotoGP t🏅itle leader Joan Mir.

"I know nothing about the engine situation," adde🦄d team-mate Morbidelli, 25 points from the top after victory last time in Aragonꦓ.

Vinales also skipped the topic o⛦f the investigation but did reveal he's havingꩲ to do fewer practice laps as he swaps between just two of his five engines.

The Spaniard's other three engines were all used during Jerez 1 and the only time any of those engines 🌜have been seen since is during practice and qualifying for Austria II.

But Red Bull Ring aside, Vinales has been using the sam🃏e pair of engin𒈔es from round two onwards.

"I'm on a reall🐲y tigꦰht line! I'm running out of engines right now," said Vinales, second in the championship and 19 points from Mir.

"In Aragon I did just a few laps in the practices so I could not make many laps and ꧑could not set-up the bike in the second race, where the tarmac and the track was feeling very different. And we paid for it. We made a bad race.

"But anyway we are going to try to do it again in Valencia with less l༒aps, trying to set-up the bike very fast. So I will spend a lot of time in the garage for sure, lik💫e in Aragon."

Morbidelli also spent some practice time in Austria with an engine fr♒om Jerez 1, but Quartararo has not completed a lap on either of his Jerez 1 engines since.

If an infringe👍ment🧔 is found and the Yamaha riders lose their Jerez 1 results, it would have a major impact on the championship standings.

Ducati's Andrea Dovizioso would take the win and move up to become Mir's nearest rival (-19 points), while Mo☂rbidelli would be the top Yamaha in fourth place (-36 points), behind Mir's Suzuki team-mate Alex Rins (-32 points). Quartararo and Vinales would both be 39 points behind, in fifth and sixth.

Since Vinales and Morbidelli then used the Jerez 1 engines again during the second Austrian round that race could also be in jeopa♍rdy, but Vinales crashed out with brake failure and Morbidelli took only a single point.
