Blown Motor Pics

[senecak19]

For those of you inquiring... Here's the culpret behind my blown motor last weekend.


This is what the air box looked like when I opened it up.



Then we found this...



This is the oil pan I used to drain the oil in the bike... the sludge was already in the pan from being outside, but those shiny bits weren't... those came out of the motor.

a kick in the nuts

I thought the fairy dust was supposed to make the bike faster...

Excuse my lack of 4 stroke knowledge, but I am guessing that the valve was the culprit?

[CBR929RE]

I'm confused. those look like pieces of an acorn but how did they get to the motor side of the air filter? the filter should block all that from the outside.

[JohnnyV]

I believe they are holes ripped/shot through the air filter from what was formerly a valve.

[wiggeywackyo]

Looks like the valve snapped at WOT and then decided to send pieces of stem or seat up into the air filter while getting wedged into the head?

[CBR929RE]

ahh yes now I see the valve being broken in there. would have been my second guess but I kept thinking stuff flows in so wasn't thinking of it popping out.

Hopefully the valves on that 750 engine your stuffing in will be a little stronger.

[senecak19]

Don't be a dick. There's a bone stock 599 motor going in.

And yes, the valve broke sending pieces up onto the air filter

[Nazo]

Don't be a dick.

You sound like Lisa and as I tell her,....I'm working on it!
I don't think anyone really thinks your putting a 750 engine in.

Hope the install goes well, looking forward to see what you can do on a fresher motor.

Can't believe no one said this yet ... "That will buff right out!"

How is the bottom of the motor?

[senecak19]

Don't really know how the bottom end is. It appears fine but with all the metal shards that came pouring out its probably toast.

[Kurlon]

I don't think anyone really thinks your putting a 750 engine in.

Of course not, that'd be absurd. No one would waste the effort. Now a fully punched out 750 with a one off billet head... NOW we're talking!

[senecak19]

Okay, now how do I get my hands on one of those?

[Pigman]

Damm.........it did eat a valve

A 600 motor with 750 parts?

And apparently didn't like part of it. Engines should not projectile vomit.
