HI THERE,JUST WANT TO POST SOME PICS FROM MY ENGINE THAT DECIDED TO STOP WORKING BY KILLING ITSELF

I WAS DOING ABOUT 80 km/h (50 MPH) AND IT SUDDENLY DIED

I HEARD A NOISE FROM THE ENGINE AND IT JUST STOP RUNNING AND BESIDES THAT THE REAR WHEEL STOP TURNING AND I ALMOST BROKE MY A*S.

THANK GOD THERE WAS NO CARS BEHIND ME,SO I COULD PARK THE BIKE,CALLED MY BROTHER TO PICK US UP AND WENT HOME.

SO THE NEXT DAY (SATURDAY 15) I OPENED THE ENGINE AND FOUND THIS...




























BY THE WAY...THE CYLINDER ITS RUSTED BECAUSE I PUT EVERYTHING IN MY YARD AND IT RAINED ALL NIGHT LONG AND I DID NOT EVEN NOTICE THAT.

AND AS YOU CAN SEE THE LH CONROD IT IS BROKEN,ALSO THE UPPER CASE AND BOTH CASES ARE DAMAGED INSIDE,AND ABOUT THAT PISTON

LETS NOT TALK ABOUT IT


ALMOST FORGOT


THE RPM`S WERE ABOUT 5K WHEN ALL THIS HAPPENED

expensive rebuild youve got yourself there.good luck with it.

danny.

Ouch. Is that rust I see in the barrel. Do you have steel liners as opposed to to original nikasil plating?

ouch .

but looking at your other piston, I'd say your engine should have had a rebuild some time ago

That looks grim mate.

I'm glad it didn't bite you, 'any landing you walk away from is a good landing'.

I would suggest that the small end bearing was the first point of failure here, I know it's only a moot point though.

The motor looks like a write off to me or at least big rebuild, crankcases are machined as a pair, new crank, piston(s), ooer, etc..........

Good luck with it and I'm glad you escaped with only wallet damage (and a pinch mark in the seat!).

That is one serious seizure, I've blown up a few engines before but nothing like that!

I wish you luck with the rebuild Edgar (assuming you are going to rebuild the bike?) I would try to find out what caused it to seize in the first place though.

Best of luck luck mate.

A fairly comprehensive failure there Edgar mate I think you need to find a replacement motor.Best of luck

thank you guys.

yes i will try to get another engine,running or not just to bring the bike back to the road where it should be.
