Engine failure

[~TABASCO~]

Any new info on what actually happened ? From the original poster / Yamaha ? Photos?

my ffiend in NC just had the rod bearing go out on his 2016 or '17 model. only 88,000 miles. dealer/yamaha quoted him 10K in parts/labor, they may or may not cover.
fyi- my top end still has not been torn down for inspection and repair.

Hope your luck is better than mine and my friends!!

Not as yet, it is in the process of being stripped down. Mr. Yamaha took it fir exploration, and I will be invited to visit at some point. But it only left here on Thursday the 24th.

Took it? Like they loaded it and drove away ? Did they only take the motor, or whole bike?
Thanks fir the info (thumbs up)

What is their plan? Replace, repair, charge you, or cover it?

I think the first will be “investigate”. Curious about the outcome like the rest of you.

I would see what Mother Yamaha thinks about it. They may show some love, which means they will get the parts or engine for you. Such an odd failure, they may want it for analysis at the factory, which means they usually will give you a new engine.

You have to work on them and don't let up.. Get your mechanic to push the buttons for a complete rebuild. It took me over a year and a class A service manager from Bobby J's to wake up mother Yamaha to fix my engine rev stall wiring issue. Brought the scratching heads from California to New Mexico to fix it FREE!!
All this maintenance and oil change done by a certified Yamaha mechanic or you? And if you do you have record of what you did and receipts on the things you didn't?
If they find a factory mechanical or material flaw you may just luck out. I hope for the best..

In 1970 I had a 56 olds that got about 100 miles a quart. Holiday gas stations had remanufactured oil for 19¢ a quart! It did keep the mosquitoes away!

It's a GMC what do you expect.. My friends had 65 SS Impala that would drink a gallon of the recycled aviation oil just going to school and back. One day it just blew a rod.

So I was told today that 1 of the 10 clutch plates (No 6) simply disintegrated. Which then somehow was sucked up through the intake, and literally just raked havoc. The question being answered now is, was it a faulty plate to begin with, or was it inserted incorrectly! See pics.

Also the left connecting rod broke, but not horizontally, vertically. Which was how the engine was still starting and running.

Geez! I've never heard of anything like that happening before. That's crazy. Did you suddenly notice anything different in your clutch pull or any slippage?
Please tell me they're giving you a new motor after all of this.

I would love to see a picture of the con rod

I can see how the oil pickup was blocked, starving the rest of the engine from lubrication. Probably caused a seized and subsequently spun main bearing leading to the broken rod. Not sure I understand a horizontal vs. a vertical rod break, but would love to see a photo of it.

. . . . The question being answered now is, was it a faulty plate to begin with, or was it inserted incorrectly! See pics.

Now, it's been awhile since I replace clutch plates, but, I didn't think there was a front or back to them. I thought they were the same on both side. So, I would vote for defective/faulty plate. I had an '83 Dodge Rampage that had an exploding clutch plate; faulty material. (yeah, I know, not the same situation)

I always wondered who actually bought these back in the day!
Definitely not as cool as a 1st GEN Subie Brat (which had the rear facing throw-up seats in the bed).

So it all came down to oil starvation. I'm good with that.

 

[Sierra1]

The new motor still shouldn't be on his dime though.

Wow what a mess! Sorry to hear of trouble like that. Sure hope it gets fixed and doesn't cost a fortune. Between myself and my buddies and then our boys there have been a truck load of burnt destroyed and blown up clutches in my shop getting replaced. Especially with the boys! Anyway I have had to clean out some metal from the sumps and oil pick ups but never had an engine fail or even be hurt by it. Guess were were lucky. Hope it all gets resolved fast and free!

Usually the destroyed clutch gets noticed before the oil pickup gets plugged by debris. I can picture a scenario where everything feels normal until you try to stop and go, meanwhile you've gone a hundred miles at 80mph with no flow.
