Naughty Yamaha

So, Yamaha have been caught swapping the defective valves in their engines for all riders....

Details are still emerging, no-one seems to be 100% clear on exactly when/how this has happened.


The best I can tell, the designs for the engine were supplied for homologation (along with a sample engine) ahead of the Qutar round.

This round got COVID cancelled and we had a 10 week break.

During this time, Yamaha changed the valves ahead of the first race in Jerez.
The same valves then failed in the high heat of the Jerez rounds and junked 3 engines.

Yamaha then apparently reverted to the original valves for the remaining, unused engines.

As a punishment, Yamaha have been fined 50 constructor championship points and 20 world championship points

The individual riders points are unchanged.

Given that the penalty for taking a 6th engine is spit lane start, do we think that this is sufficiently l artificially lenient?

Dorna just keeping the championship alive?

I haven't read about any sanctions yet. Is it fair to penalise a rider who has unknowingly ridden a non compliant bike? And is it right that Yamaha only cop a team sanction, whereby a rider can still claim a title on a non sanctioned machine?

It's an interesting question.

I think this is a case of the rules being made up as they go along.

If this had been discovered at the beginning of the season, I'm fairly sure we would have seen individual rider sanctions being handed out.

As it happens, this attempt at circumventing the rules (assumingly for increased performance or reliability) has completely back fired.
They lost lots of engines and had 2 race retirements. As a result of the lost engines, they have had to detune the remaining engines and are now in deep trouble for the last 3 races (Mav only has 2 engines left and is saying he can't do all the free practise sessions in full as the engines won't last)

I've think they've looked at how situation has unfolded and have decided the riders have probably suffered enough...

Wonder if Yamaha are required to go back to the "faulty" valves?

This is a good question with everything being already homologated for 2021. One would have to think if Yamaha change their engines then they must be punished again next year or it opens up for everyone else to do the same.

The valves that were part of the original homologated spec are actually the 'good' valves and are what all of their current engines are using.

They actually changed the valves for the Jerez rounds with the ones made from Swiss cheese - It's not actually clear how this has been done as the engines get sealed and by all accounts, no seals were broken.

So they are already running the valves that were signed off officially, but they managed to get different ones in for Jerez...

Mav has just confirmed that he talking a 6th engine and will start from pit lane.

Yamaha have attempted to cheat and in doing so, from the first race effectively reduced their engine capacity to 3/5 of it what it should have been.

How many heads will roll?

It's a team sport. To get a good result, the rider benefits from the bike as much as the bike from the rider. So if the bike isn't legal, the rider hasn't competed legally. If the rider is penalised, the constructor's result will be affected. It's pure politics why the rider's points aren't affected.... that's down to the power of the dollar.

I've always felt that engine homologations are terrible for those behind and a free ride for those at the front. I think it's even worse when there's a reliability issue amiss. The team is then stuck with it for the entire season or even the following season depending on the period of homologation. I know the sport and teams need to implement rules to contain cost. But the rules should minimise homologations that lead to fixed (ad|disad)vantages that teams are unable to try to correct as needed over a season.
