2007 Yamaha FJR 1300 Broke Down-- MORE CARNAGE

In this video I removed the valve cover and intake camshaft to see what kind of clues I could find as to why this happened to my new to me FJR.

Someone did something wrong when adjusting valves maybe? Never heard of this with an fjr

[@herbiesgarage681]

Yeah, it was ashame to see this nice engine have this catastrophic event. When I took it apart it looks barely even used on the inside. I hear that a lot about the fjr engine and I think it is a very reliable and well built engine.

Looks like design malfunction, maybe you can get by with just a head. I couldn't ever trust that again lol.

[@herbiesgarage681]

I bought a 2012 Engine on Ebay, this engine would cost too much to fix. I'm not sure of the cause really. Thanks for the comment.

[@johnhopperstad2785]

That’s what happens when piston contacts the valve either you spun a rod bearing which is unlikely or your cam chain was so worn out your cam sprocket skip a tooth or your cam tensioner failed

[@herbiesgarage681]

I’ve checked the cct and cam chain as well as alignment, everything is good. I believe the previous owner did or had done a valve adjustment and something went wrong. From the first day I got this it acted funny on #2 cylinder with the throttle body sync. Something held the valve open long enough to come in contact with the piston. A lot of carnage in there.

[@edgardomatos6923]

wow , absolutely crazy . why does that happen. ?

[@herbiesgarage681]

I'm not sure, it's kind of a mystery but I suspect someone did a poor job on the valve adjustment, but just a theory.

[@frontcentermusician]

Yep. Find another engine for peace of mind. Keep that for parts.

[@herbiesgarage681]

Yes sir, that is exactly what I did, Thanks for the comment! : )

[@JerryHawk250]

Hopefully you have no other damage besides maybe the piston.

[@herbiesgarage681]

It's too much damage, I ordered another engine on Ebay

[@kensmith3665]

Is that a thing with FJRs?

[@herbiesgarage681]

I don't think that it is, everyone that I talked to about this engine said it is a bulletproof engine. I just happen to get the one bad one. : )
