Apparently there are other suppliers that has noticed this rod-issue...
Hurricane is also awake on the matter...??

So, don't shoot Mcx just because they highlighted it and came forward with the apparent issue first of all!

Why would MPI try to explain what MCX is doing????
"Hello,
The MPI Viper turbo is continuously durability tested by Yamaha, It is retested exactly for this reason, and almost every model year has changes. The “New” 2016 motor was in testing last year. Fortunately these changes which include Rods, Crank, Head, etc are new to the consumer this year, but were fully covered in durability testing last season (one of the advantages of the Factory Yamaha relationship). We have no opinion as to the new components at HP level above 240HP. We have ALWAYS maintained that it was/is not advisable to operate this motor in “stock form” above 240HP. Since the 1st generation of this motor in 2004/2005 season, we have advised modifications for HP levels above 240HP (after market rods, head studs, etc). Our stance on the 2016 Viper motor is that the 190HP Yamaha version as well as the Stage 1 upgrade is “Reliable” with a stock motor. Durability data backs this claim. We consider Stage 1 with pump kit and 4th injector kit to be 235HP (examples: 10PSI at Sea-level and 14PSI at 10,000ft). "
Hurricane Turbos has also delayed shipping of their turbo kits until this is solved.
That is frickin' hilarious! You should consider being a life insurance analyzer-Ben Stiller/Along Came Polly has nothin on you

Im bringing this back up to fill those in that may be concerned with what I have found out.
First, I talked (ok perhaps yelled at times) at my dealer about this. He is a good man and cares. He didnt find out about the engine change until this fall.
Anyhow, he called his Yamaha rep, Mpi, and Troy Johnson and basically he said they are not having issues with the 180 kits. ( He knew full well I wasnt going with a 180 kit). But he blamed the failures on those dang Canadians and low altitude.....
So, I had Brad do a little digging for me, and this is what he has come up with.
First, the 180 kits are not having issues. So if you are running one of those setups you should be good. Thats where it ends.
Mcx lost there 190 kit after an hour on the dyno. Hence they have stopped shipping kits. So has Hurricane..
Basically the rods will no longer hold up to those power levels. It is a fact and one you should face if you are looking to run these engines at or above those levels. Corrillo should have there rods out in a few weeks, but I was told there is a Swedish company that has been working on it since the first failures were known. They should have rods out first. I am not sure that will help us much over on this side of the pond but?
Regardless, if you have a late model 2016 engine and it is boosted, and you are running over the 180 hp range you need to be concerned. I was told with Evo pulling timing on there kits, that the 210 kit may be ok, only time will tell. The other kits are not pulling timing.
Take it for what it cost you. I am going to chance running the 210 tune until i get my hands on some Corrillos.. It sucks but what do you do....

Man what is Yamaha doing?? This is such a step in the wrong direction. So how about the crank itself? How do we know that will hold up?

I dont think anyone knows that really. The rods have been a surprise. Once the rods are fixed and some time is spent on the machines, I am sure we will find out. I would honestly be surprised if the crank has issues. It would have to be very weak to have issues... but who knows.
kind of sad that the very thing that sold people on the four strokes is now weaker then the two's.... I can run big boost on a Cat 800/1000 all day long without worry!
I hope the rods fix it....
Just FYI. I have another solution for the rod problems.
The older Nytro/Viper crank, rods and pistons fit straight into the new engine, so the the balance shaft/weights. I bought a used crank, rods and pistons from a 2014 Viper with 25miles on it for around $800.
Decided not to wait for the Carrillo or Swedish rods that MAY come in 4-5weeks.

If this is the direction they want to go then my next sled will be a polaris. I might as well buy something that I know is going to break on me instead of a false sense of reliability.
Yamaha reads these forums...YOU ARE LOSING SIGHT OF YOUR CUSTOMER BASE. We want sleds that last!
