Flashing the ECU is probably a sticky point as it changes the dynamics of how the engine runs, Yamaha would probably push back if you had a failure like the ones experienced by a couple of owners here. I think the safest assumption would be if you flashed the ECU, and especially if you put on 3/4 exhaust (sans catalytic converter), you have voided your warranty and a Y.E.S. agreement wouldn't be worthwhile. Just my opinion. Yeah, that makes sense. The net cost of everything that may fail outside the engine would probably be less than $460, but I still think the 2 failures were anomalies. I don't think I'd try to pull wool over the eyes of a dealer by lying about the decat. It's a risk I more or less accepted when I installed. |

Mike I think you've over estimated the consequences of using 15W-50 a little.  Surely a family of 5 won't all die?  ?? |

Not to mention the emotional distress from losing her husband and children. All because of 15w50....such a shame  |

I simply said 10/40 and 15/50 are DIFFERENT oils, and it pays to learn about that. And unfortunately, Yamaha doesn't specify the conditions which each is best. If you don't run the bike hard constantly, and use the bike in cool weather, 15/50 is not the best oil to use. If you did your research, then you wouldn't be ignorant  . We all are ignorant on many subjects, but at least I admit it, and sure as hell wouldn't engage in a discussion without doing my research first. But to each his own. Was just trying to help, but I'm done here with the oil subject . On the warranty issue, running the bike decatted without a tune is just plain stupid IMO, as the engine runs way too lean. So either do it right, and acknowledge your powertrain warranty is over, or don't touch the bike . And those who think Yamaha wouldn't know if the cat was removed, they're not that stupid. |

A guy from the UK had a catastrophic engine failure while still under warranty, (2 years btw in UK)
yamaha said it was caused by lack of oil, the guy swore he checked it a few days earlier and it was fine but they came back with statement about how the engine can use a litre of oil very quickly, they gave figures but i cant remember what they were, but it was something ridiculous, anyway they refused to pay out and he was left with a huge bill, ive not heard of any others in the UK though except that one and its a very popular bike.

It's hard to know who's telling the truth with just one side, but for better or worse, just like with humans, 'forensics' can tell what happened. And it's relatively easy to tell if it was oil starvation, meaning not enough oil. So my guess is Yamaha is correct. He could hire a lawyer and mechanical experts to challenge Yamaha, but he better be right, or he'd lose a ton more money than just paying for the damage. If he didn't check oil level before his last ride, not worth fighting (or blaming) Yamaha IMO, and I assume that's what he decided as well. But my main reason to post is for everybody here to learn from his lesson: CHECK YOUR FLUIDS BEFORE EVERY RIDE. With our bike, it literally takes a few seconds, since all fluids (coolant, oil, brake fluids) have a window. I go a step further: keep all fluids at the max level, and also check tire pressures, since our bikes don't have TPMS (I miss that). The last one can save your bike and your life, so very important too.

i found the original post on facebook and this is a quote from him
"no warning light ever.... i checked it and it had 4.1litres.... 400miles later it had 2litres and a shattered shell bearing"
i would have expected an oil warning light at least
scary story

I'm calling BS on Yamaha UK's statement that "the engine can use a litre of oil very quickly". That's true only if there is a massive leak (loss of drain plug or filler plug, major seal or gasket leak, or ring failure, and probably a few other things), but a normally functioning engine/transmission with few miles on it will NOT use a litre of oil very quickly. If a litre of oil is lost in 400 miles there is a problem with the engine, and if Yamaha is copping to the explanation that this is somehow normal they are being flat out dishonest, not unusual from a corporation protecting their assets. It doesn't do much for their reputation but if they figure enough people won't find out about it they will often take the deniability road. Harley Davidson has taken this approach for years as there were always enough new customers (marks) entering the market to make up for dissatisfied customers who got burned by a massive failure so H-D merrily carried on and said 'tough luck' to the unlucky ones.
The oil light on our bikes is an oil PRESSURE indicator so depending on how the system is set you could loose a couple of litres of oil and the light might not turn on, as long as pressure is maintained. On the previous FZ1 bike the oil light was a LEVEL indicator so you would have gotten a light if the oil was being depleted. No idea why they changed.
And it is always a good idea to check the fluids before your ride. I do it at the end of the ride as I clean the bike up before rolling it back into the garage. If the oil level is good at the end of the ride it will be good the next time the bike is rolled out. And I always check the tires for any nails or debris that could cause problems. I've had a couple of small nails found that didn't cause loss of pressure but had to be taken care of. |

"no warning light ever.... i checked it and it had 4.1litres.... 400miles later it had 2litres and a shattered shell bearing" That red statement is BS, since you can only check level thru the window, not exact quantity. The only explanation of exactly 4.1 liters is that he just changed (not checked) the oil, and could have messed up the job by not installing the oil cap, or something else. But leaving that aside, let me explain why the entire sentence is just BS IMO. First of all, It'd be extremely easy to prove that massive oil consumption/loss without any engine disassembly: spark plugs would be fouled to hell (I'd be surprised they'd fire that long), exhaust would be very oily, and airbox would be an oily mess, and no evidence of an external leak. Why no word on that? But here is why I believe that entire sentence is BS, and without further evidence, I wouldn't put the engine failure on Yamaha: 1. With that oil consumption rate, a CEL would have been triggered way before 400 miles, with many DTCs (misfires on each cylinder, etc). Very easy to check that the CEL light is working properly by turning ignition on. 2. Bike would have run like crap for the last 200 miles (if not more), and smoke like a chimney. No way the lack of performance and stumbling would have gone unnoticed until engine seizure. 3. And finally, if engine seized due to oil starvation, the low oil pressure warning would have triggered when oil pressure was low, giving him a chance to shut the engine off before seizure, whatever the cause of oil loss was. Again, very easy to check if sensor and light are working properly with ignition on. My guess with the information given is something else happened (possibly a botched oil change job), and he's trying to weasel his way out of a new engine. Without any further evidence, the blown engines remain at 2 (this one not included) in my book . |

i did wonder about the 4.1 litres bit myself, although if you put 4.1 litres in and it was halfway up the window, you could assume that every time you check and its half way theres 4.1 litres in it.
that said, it sounds more like it dumped the oil rather than lost it some other way, maybe the sump plug came out, that happened to me in a car once, but as soon as the oil light came on i stopped the car and the engine wasnt damaged.
i guess we will never know what really happened
