I have a buddy that bought an 06 636 for the sole purpose of stunting. He's been doing a decent job of converting and adding crash protection. He was practicing 12 o'clocks and stopping/starting off the bar. He pulled away and everything stopped. Motor is locked-up solid. No oil in the crankcase. We are assuming the oil has it hydra locked, but don't know why. He is tearing it down now.

Any ideas if there is something that needs to be plugged or disconnected to prevent this in the future. Also any other helps would be appreciated.

Thanks

If I could draw with keystrokes, I'd draw you a picture of a baking pan. In the middle is the oil pump pickup tube. Say I lift the pan, the liquid that was laying flat, waves to the rear edge of the pan.

Now there is air on part of that pickup tube or screen. If I stand the pan vertical, imagine no oil for seconds, as the pan hangs there, the engine looses oil pressure to keep the parts from grinding on each other. That oil pressure floats the parts in the middle of the tolerance. Lose the pressure is like dropping a ball from your hand to the ground. You had that pressure to hold the ball from galling on the ground. So, imagine the cam drops on the float. The springs push metal into metal. At pressure, you are pushing a solid liquid up against the cam tower not a hard cam steel metal up against a softer metal which is aluminum.

Imagine the rod bearing or ball bearing being hammered on the fire stroke. It slams down on that oil film. You lose oil pressure = BAM! Is the slam on that soft aluminum bearing insert. BAM! is it squeezes out and galls up being hammered as if you took that rod and just smacked the bearing insert.

Heat builds up, and you get the rest of the story, being the engine parts are at the bottom of the sump pan. How about we figure out that if we have a pickup at the rear, it needs some gate or resistor panels that keep the oil from channeling toward the front on the hard braking we are now in.

Remember, we are at hard braking is one slosh to the front is no oil loss on the hang time entering a corner, you fist slow down for it. OK, so we have the gate gaps in place, hard brake, hard accel, and wheelie covered. Now what about a front stop pee?

Pizz in my pants all day is think up a sweep arm in the down sensor is a pendulum catching stop pea on a pea or a dime you wheelie up from it and any other stunt is follow the oil trail.

I would need to see the oil flow chart. This gives a picture where the pickup begins and how and if you can design something from there. Now, you said, "no oil in crankcase" means to me, zip, zero, nada. Next, you mention "hydra lock" as if there is oil in the crankcase. I have to combine those two thoughts and assume you meant there was no oil in the crankcase but at the back of the case with the transmission parts say.

Therefore, you have to search if the aftermarket is addressing the design you might need as far as chasing that oil loss syndrome is not a hydra locking effect. There may have been a momentary loss of oil at the pickup tube or pickup screen. This would be a design change you would have to over ride so as not to lose oil at the oil pump pickup area.

Try this:

If this is strictly for stunts, my warning banner is out [you are on your own theory in practice] being someone may have tried this; blew out the seals and all. But since I have the engine down, I can now see a visual of how much oil I can get away with. Say, if I can EYEBALL a case to oil pickup tube?

Eyeball the case horizontal~over the pickup tube, both at the transmission angle in the wheelie mode is straight up. Where is the oil level? Is it over the tube as if I double checked and flipped the case to be at my wheelie stop it, I get it already! Now WOT?

That is what I am saying> is not to WOT the bike anymore. I now need a catch tank so if the pressure in the case >over loads< the air, then that oil is heading out the breather tube. I need to see how much pumps out first time out. I see it fill up, she is killed the instant I see it coming out.

You loose oil pressure, your buddy may have a gauge "how fast in time it took" to cook it to a welded ball of metal. So, as the test goes, I have no clue how the pro'z address their oil pickup delivery??? This ideal of over level is what I would do: IF mine were to be a stunt bike only. This is how I would handle a slow rpm runner that stunts at 3 levels. Meaning, the playing field works on either wheel or both.

Ok Hub. First and foremost, thank you for the reply.

I know and understand the function and path of the oil as it is supposed to be. I know that some bikes oil pick-ups are not fixed. As they swivel to follow the oils path in the pan. I however, don't know if this bike has that system.
As you said with the lack of oil "zip, zero, nada" is correct in part. There is no oil in the bottom end of the engine to see through the sight glass after an hour of sitting on both wheels. In conjunction, no oil has come out of the bike.
Therefore my conclusion was that the cylinders were hydra locked from the top. I am (for the lack of a better term)assuming the oil was pumped into the air box, then into the combustion chambers which locked the pistons hydraulically. Since that is where the oil was.

Once the oil was drained from the upper engine parts, it started and ran flawlessly other then the smoke for 15 to 20 minutes.

I think that a catch bottle would be the way to go. The oil would go into the bottle in an inverted maneuver then flow back into the motor upon descent. If indeed the oil is pumped into the air box, we need to know from where and that would be the feed line for the bottle. The pick up tube is still a question, but maybe not as serious as it was able to pump the motor empty in a wheelie position. Stop pee is the other side of this card.

No oil no matter what wheel = Seized parts. Tear it all down.

You have damage if it seized. You also have to understand how to design that catch tank to fill a bladder and then feed the oil back into the engine. You have 14.7 psi to mess with on every stroke. So for one action, there is an equal and opposite way to plumb that oil and air pressure... Let me know how you did it.
