Well maybe my ears are wrong but it sounds like the bike has had exhaust mods.
If so questions to be asked.
Was the cat removed to?
Was the bike tuned?

That really sucks and scary how that went down could not tell about exhaust but I could hear something going wrong a little bit before it broke almost like the timing chain let go maybe who knows. It would be nice to find out though on new bike hope it's not out of warranty.

The owner states in the video about oil blowing on his brand new Austin Racing Exhaust. So.....probably with midpipe and maybe not a chance to flash tune yet?  Anyways, hope warranty covers it! |

Did not watch the video in its intirety its actually hard to watch to be honest nobody wants that to happen to anyone. But if that is the case with this guy's problem then it could be a valuable lesson to learn make sure you know what your doing with engine mods.
Not saying this is the case here but I heard over and over over the years frome forums and engine builders about air fuel and piston swelling from heat running a lean condition.
Personally I would not run a cat delete with out a flash pretty much all bikes come leaned out from the factory as it is with cats

Anyways, hope warranty covers it! doubt it. I rode mine like hell with a 3/4 exhaust and no flash and had zero problems. Throwing a rod through the block isn't because of a cat delete and no flash |

I gotta agree with that. You're not going to get this type of catastrophic engine failure from no getting a flash on an aftermarket exhaust. Sometimes these things just happen. We're riding heavy aluminum blocks that have 4 cylinders that are generating sometimes 10s of thousands of explosions every single minute. Sometimes it just goes bad. It's really a wonder how it doesn't happen more often.
My Triumph with the 16,500 RPM redline, just a wonder that the engine just doesn't explode at that level.

will84, I was just pointing out that owner could have been in a lean condition. There are several factors that could lead to a catastrophic failure. You rode like hell with a 3/4 exhaust and no flash, but I am assuming you eventually got it flashed??? Anyways, I hope we can get a root cause analysis from the original poster and help us all in the process!

I wish the spark plug where easier to get to then you would be able to see or at least a better idea on how the bike us running as far as air fuel.
As far as the video it did not seem the guy was in the high revs to throw a rod I've only heard stories about rod or bearing failure in the high or redline range

Ok so I'm a dumbass I just watched it again and read the caption and clearly the rider thought a rod let go so I stand corrected and why it let go could be many reasons.

I don't get people riding around at stupid high rpms in 2-4th gear all the time. They're definitely built to handle high rpms, but I don't get that crap.

It was my license plate on my 95 Z28 back in 96 and I’ve used it as a forum name forever. It is pretty funny though! I used to do my share of drag racing at the track and only with manual transmissions.

Hey everyone, this is my video and I am the owner of the bike.
The bike had an Austin Racing exhaust. It had a midpipe so no cat.
I installed it around 1600 miles and the engine blew at 2300 miles. No tune. This happened on Saturday night, and I had a dyno tune scheduled for Tuesday morning.
The bike is under warranty. But yamaha wants to rebuild the motor and not replace it with a new motor. I have reach out to a lemon lawyer and he is going to try and have the bike bought back or replaced. Feel free to ask me any questions about it.

I don't get people riding around at stupid high rpms in 2-4th gear all the time. They're definitely built to handle high rpms, but I don't get that crap. I mean this isn't necessarily applicable to the current video and street riding In a straight line, but as far as cornering and riding the bike agresively, this is the best way to ride the bike for a few reasons. You're in the ideal powerband near max horsepower and torque making the bike more responsive, the higher RPMs make the bike more stable and less likely to "bog down" when cutting the throttle or reapplying it which in turn can prevent wheel spin and crashes, and you have more engine breaking helping you slow the bike down and keep it stable during deacceleration. There's a bunch of science to it that I'm just not smart enough to explain as far as centrifugal forces and all of that. So generally, you're more stable and safer taking a turn in 2nd gear at 10k RPMs vs taking the same turn at 3rd gear at say 5k RPMs. Take the same turn at 4th, 5th,6th at very low RPMs and youre just asking to crash. |

I have reach out to a lemon lawyer and he is going to try and have the bike bought back or replaced. Feel free to ask me any questions about it. Thanks for reporting back! Lemon laws differ greatly from state to state but they are generally straightforward. Unfortunately most won't declare a motor vehicle a lemon until after the dealer is given multiple (usually 3) chances to fix it. And unfortunately if it's their perogative to rebuild the motor, then you might be stuck with that. Just document everything as even when the bike eventually goes off warranty, you still have a case against them. But obviously your lawyer knows more than me about your states laws. I won a lemon law claim against GM in NJ so I went through the entire process there. |

Lemon law doesn't apply in your case unfortunately. Lemon law requires usually three trips to the dealer to fix a problem that doesn't get fixed.
If Yamaha is willing to rebuild it then that's what they do. I've worked in shops for 20 years and never have I had a manufacturer replace an entire engine. I've rebuilt many under warranty

Sorry to see that! but happy to see no accident/injuries (most important). What exactly happened? you have some pics to share of engine damage? What engine oil you were using? |
