Are you saying that your dealer guaranteed you that it was OK for you to run pump premium at 18lbs. of boost?

I'll side with apexman. Dealer did the install, and setup. Told him what he could run for fuel. He runs that fuel, and engine fails. Dealer is backing up their work, they made the mistake, and they're standing behind it.

Why is apexman getting trashed for this?

Now, if apexman, turned up the boost, past dealer setup, or didn't run the required fuel, or fiddled with the setup, then the dealer should worry, void warranty, whatever, then that's different.

If I were the dealer, I would purposely set the boost, under the pump gas limit, by 3 lbs. Safety margin. imo

Ummm, YA, thats exactly what i would be calling him. The results are laying in your crankcase or belly pan. I know your dealer, Miles, and i dont know why he would try and re-invent the wheel to claim from a dyno result that pump fuel is ok @ 18lbs. Fix your "lean" spot and go run it again on pump @18lbs and i'll bet you the results will be the same.

And Geno, no ones "trashing" Apexman, just stating the obvious....... If your dealer told you to run 18lbs on pump would you ? No, prolly not because you've got some knowledge on these turbo Yami's, which is my original point. 1 person in the world says pump is fine to 18lbs, but every other person says its not. Common knowledge or common sense must prevail at some point.

blowm motor on nytro

ok si just talked to mechanic #2 piston shows signs of detonation (my mistake for saying lean) they are going to reset for 15 lbs.theye also have a feeling that boost control rod may have froze. i am only relaying info FROM THEM SO NO ONE ELSE HAS PROBLEMS.so darko if sets boost at 15 lbs at my elevation of 4500 feet and says i am good to go do you think i should tell him he is full of BS

stop being haters

Doesnt sound like this guy is smacking on anyone, sounds like he is braging up his dealer as he should.
I dont know how the snow is where he is rideing but anytime in the last month around here I couldnt have told you what my sled was running for boost till I stopped and cleared the guages. It sounds like it went lean because the stock fuel system cant keep up with 18 lbs. If the rod was short and not allowing the wastegate to open all the way he may not have even known it was over boosting till it was too late. It may have worked fine till he held it open for a extended run.
If i bought a turboed sled and was told I could run pump at 18 by the guy who put it on i would ? it but If he was willing to back it up and fix it i would run it..

Bahahaha, your storys already changed on this thread 3 times.

Lets get back to the FACTS.

- you said MILES "GAURANTEED" to you that runnin 18lbs on pump was fine.Right ?
- you also stated it wasnt a fuel problem
- also that it was lean
- then you also claimed it was dyno'd for 18lbs on pump.

NOW, you chime back in with a total different story and ask me if i would call him full of sh!t ? We'll someone sure as hell is full of sh!t.

hey darko i do not know why you want to argue so badly, i posted this so this does not happen to anyone else. the facts are i was told to run premium and i did,i was told sled was set up and ready to go. i did not change anything on sled, #2 piston is toast and so are case halves boost will be reset to 15 lbs and we will try again. and yes miles is an excellent dealer who stands behind his work.

 

[Thistledoo]

From what I have read on here and seen 15lbs is too much too.....do you want to push the envelope to the max or do you want to just ride at 12lbs and not have to worry about the whole deal?? Wonder if Miles has ever been on MXC's website....maybe he didnt believe eric and his dyno?? I'd tell him to set it for 12 on pump like everyone else and ride or do you want to be hauling it back weekly??

i will tell them 12 lbs but miles will have the final word here

 

[DARKO]

Who's argueing, all im doing is trying to get your facts straight. Lets not forget your the one asking who is full of BS and who to tell there full of it.

I know Miles is an excellent dealer, and i also know hey would NEVER tell you or anyone else that running a MCX Turbo nytro at 18lbs on pump is fine, or "garenteed" or he dyno'd it to run 18lbs on pump.

In one sentance your making him sound like a stand up dealer by standing behind his work, which i personally know he is and always would stand behind it. But, on the same note you telling people that he told you it was fine to run that high of boost on pump doesnt make him look good at all.

Here's a tip for you, next time you fill up at shell, chevron etc and then see 18 on the gauge, turn your control rod out 3 or 4 turns or run C12 or AV 100ll. MCX, Alpine etc with head shim are safe for 14lbs on good pump premium @ 5000' ft or more, any more than that and your rolling the dice.

All a thread like this that changes by the minute does is confuse the sh!t out of newbies to yamaha, boost etc. It's pointless to fire up a thread with guessing, wrong information, stated claims that are reversed later on etc etc.

Wonder how Yamaha feels?

Here's a thought - if Yamaha thought that a Nytro would be ok on 15 lbs boost on premium pump fuel, they would likely build a production model that would run 10 lbs boost on 87 gas and call it a "limited edition" and offer full warranty with it. I don't know your dealer, but I suspect that Yamaha is unknowingly paying for the repair under their warranty - and that is fraud, plain and simple. No manufacturer should be expected to pay for any mods that cause damage to their equipment. That's one of the reasons new sleds cost so much. My 2 cents.

That's a fact. If anyone reading this, is a DIY'er. Set it at 12lbs., for pump, at 5000ft.

I believe he said they were going to fix it at THEIR cost. Not warranty it through Yamaha.

Yeah, I wonder if Yamaha is unknowingly paying for this one?

Bingo!!!

 

[BigFish BC]

wow this is a crazy thread thought it was common knowledge by now( 12LBS BOOST ON PUMP FUEL)you take big chances above that once you take a few runs at a hill & heat the motor & turbo up,deto becomes a problem.every time i go out i find a spot to take a quick test to make sure my boost is good.it only takes 3-4 good runs at a hill at 4-5lbs over boost to take out your engine.this is why most guys recomened a higher oct than needed if you do not have a boost gauge & a/f gauge & actually use them there is a good chance you will be putting a new motor in your sled ,all this power does not come for free.

 

[Turbo Tim]

waste gate rod was set to short dealersaid premium was ok for some reason the motor got to lean not afuel prbolem. will be ready for weekend and we will try again

I can sum this up for everyone .
Pump premium + Turbo = Blown engine .

Who cares if yamaha is paying for it, you can't honestly say that if you were in this guys shoes and the dealer said "hey bud i'm gona slide your $5000 engine through on warranty" you wouldn't do it? anyone would, if not then your just stupid, we pay $14,000 for a machine that costs about $2000.00 to build so IMO take what you can get and your fooling yourself by thinking prices would go down if less people would make warranty claims!

If anyones getting ****ed in the sled world its the consumer not yamaha!
