got my sled 2016 mtx viper out for a ride north of here 60 miles. ran great for 20 miles with new rods and new mpi turbo then she quit .something locked up took it back to dealer starter locked up on flywheel.I was running around 6000 rpm and she quit can a stater really kill the motor.too bad it quit quite a difference with the turbo

Yes. One of my worst nightmares. Should be a recall. I assume you have the early engine?
 
late build 16 with new rods just installed as turbo was installed . looks like oil hose that goes into cover where ringear is got loose so we lost oil pressure and why starter locked up engaged . looks like a longer hose would keep hose from working fitting loose. dealer has been great got warranty left that's good first t ime yami left me stranded dating back to the 70,s

I would look hard at the solenoid. There is plenty of oil in that cover. I think the hose you are talking about is the one added with the Turbo. Thought that was just vent. Is the One-Way bearing shot along with the starter? First 16.5 new engine with starter issue. Sucks!
 
Like cannondale stated, make sure the starter didn't stay engaged due to a stuck starter relay. Pull the starter apart to see if the magnets came loose due to overheating and locked up the starter while it was engaged. Having an indicator light like many Nytro owners installed to detect a stuck relay after startup still wouldn't be a bad idea.
 
the hose added for the turbo that goes into where the plug was. was loose and Yamaha thinks that caused the issue. I don/t know waiting for new starter
 
I find it hard to believe that caused an issue with the starter clutch or gear. There is no oil pressure in the stator cover that would cause a starter clutch failure and that hose doesn't carry pressure. If you lost enough oil from the loose fitting on the cover I'd be looking at possible valve train and/or connecting rod damage which should occur before any damage to any other internal engine component. If The engine did loose oil pressure due to no oil and the engine locked up I'd bet a connecting rod seized on the crank. How low was the oil?

My dealer ALWAYS replaces solenoid with any new starter. Its good insurance.

I don't see how the oil return hose from the turbo bearing that goes back into the stator cover had anything to do with starter locking up, I'm very familiar with what your talking about, i just installed my turbo last week, like Grizztracks said, unless you lost oil and locked motor up.
 
engine is free after starter is disengaged and full of oil
If dealer doesnt replace Solenoid. Do it yourself. They are very affordable and sure sounds like cause of issue. I would want to see old starter. If teeth are missing since it happened at 6000rpm they should be retrieved or stator or even engine damage could very well be in your future.
 
If the starter stayed engaged until a failure occurred that locked the engine enough to stall it I definitely would be looking at the gears under the stator cover. The starter gears aren't that strong and you'd think a lockup would have done some damage to them.

HOW MUCH OIL WAS LOST?
did it lose enough oil that the engine shut down because there was no oil pressure?

no codes no alarms just a couple ounces of oil lost
 
Oil loss did not cause anything in the starter or starter gears/clutch to fail. If the gears and one way clutch aren't inspected a complete engine failure could occur if any metal drops into the engine. As stated, it's common practice to replace the starter relay after a starter failure.
 
thats kind of what I THOUGHT. should have never added turbo and have them change rods was trouble free for 1800 miles and they reflashed it
