1199 Sudden Engine Vibration on track...

So not to beat a dead horse but what changed between being ok with riding the bike with a sudden vibration to now where you’re worried about the bottom end grenading? Amazing that you put all those others at risk just so you could enjoy a few laps. I’m with bp and calling that a dumb self-absorbed entitled move

How many miles on the bike and are you the first owner?

What’s the history of the bike?

6k on the bike and no I’m not the first owner.

Full service history with the bike.

Split the casings and found this…. Failed main bearing, looks like something managed to get in there! That would explain the vibration!!

Interesting. I normally see conrod bearings versus the main bearings...?

Curious have you pulled the crank & rods and inspected the rod bearings?

What did yours look like!?

Some more pictures of the rod bearings, not sure if they’re that bad?

Can you feel any of the lines on the bearings with your finger nail?

Make sure you clean out all oil passageways with some compressed air. Those bottom end bearings look like they’ve been oil starved. Prob from your water pump gear disintegrating and clogging a passage. Those score lines are a tell tale sign. I think you caught it in time where you’re good for a rebuild

Upon stripping the bike down I found that the oil cooler return pipe to the radiator was blocked I rekon that’s what’s caused it, everything just got way too hot, oil too thin ect. Oil strainer was clean with hardly anything on it and there weren’t that many pieces from the water pump gear that had come off and I found them all.

Bit of a shame but I’m going to break the bike down for parts. Don’t want to faff around rebuilding the engine to find out it’s something else!! It’s been fun stripping it all down so at least I’ve got something out of it .

Thanks for all the help on this everyone

What was the return pipe blocked with?

Gunk and crap where the bike had been sat for a bit! It’s only a small pipe isn’t it. What a shame!

Sorry to hear but I totally get it. Sounds like yours was a case of the gear followed but a number of others things likely started from the gear. If you change your mind and need help let me know just too bad you are so far away!

Thanks very much Seth much appreciated

Guess it wasn’t so smart flogging an engine w a bit of a vibration

What do you mean?

In your original post you noted a whine coming from a disintegrating water pump before the trackday and despite this still decided to stress the engine. And even after a significant vibration you decided to keep going. It’s not surprising that the oil return got plugged from the plastic/fiber shavings from the water pump gear. Not sure it can be any clearer. Hate to say it but this is your fault

dude honestly what is your problem haha. You’re a sad sad man, just remember the world doesn’t need people like you.

Of course it’s my fault you moron, I don’t think we all need to have that confirmed do we? And nobody was asking whose fault it was were they? What a strange thing to say. The post started asking advice on what people think it was not asking if people thought it was my fault. Absolutely pointless comment trying to get a reaction. I took the bike to a track a flew round for the day, had a blast and unfortunately the bikes oil coolant return line was blocked from corrosion from being parked up for so long which cooked the motor whilst it got to hot, absolutely nothing to do with anything your saying about. Certainly nothing to do with a couple of bits of plastic that came off the gears which I found in the sump. I had a great day, in fact having so much fun I didn’t want to come in and loose a session so I kept riding it and yes probably caused more damage but who really cares, it’s what it’s all about and I had fun, some people would call that living, something you don’t know a lot about. Bikes now in bits, do I really care? No! I’ve quite enjoyed taking it all apart actually. Now I’ll just ride the v4’s on track and sell this for parts happy days.

You’re no help to anyone, completely useless. All you’ve done on this thread is make negative unhelpful comments. You’ve actually taken your time to be a problem that’s how pointless your time is to you. Instead of spending time with family enjoying the great things in life you sit on here just being annoying. I feel sorry for you, if your parents could see what you’ve become they would be ashamed you absolute looser.

Enjoy wasting more people’s time on forums and making yourself look even more little and sad than you already are.
