Hey everyone.
Last night I was playing in the ditch a little and I we ended up putting my XTX on it's left side for about 4 mins before my buddy could help me right the beast. Heavy to push it back over myself and I weigh 225 lbs and work out regularly!! Anyway to make a long story short oil and gas were coming out the left side vent on the cowl. After we righted the sled I checked the oil and it was low so I added a quart. The oil light went off but I could not start the sled. I waited another 20 mins and tried again but not go. It would not turn over. Any ideas? I have her sitting on my trailer and plan on looking at it next Saturday when I have some time. I know I will need to clean the airbox and probably change the oil. Is there anything else I should be checking. Could there be an possible engine damage? Anyone else have this happen?
Happy riding!!!!!

Is the kill switch down?

could be hydrolocked from the oil, if it got into the top of the cyl.

I am thinking hydolocked as well. I am going to pull the plugs and clean the airbox then turn it over to get the oil out of the cylinders.
Thx!

When did hydrolocking get to be so popular?
Just to get an idea of how difficult it would be to pull a large quantity of oil into the throttle bodies you should pull the air box cover first.

Mine has been upside down for three hours-accident. Flipped it over- started up but oil was down somewhat...It did smoke for a bit

The big difference between being upside down and on it's left side is that when on it's left hand side the oil take i at the highest point and on the perfect angle to drain off into the airbox and into the cylinders. IMHO this is a bad design. There should be some sort of shut off. Yamaha should also have a warning label on the sled that let's the operator know that if your sled is on it's left side do not attempt to start it after righting it as it may cause engine damage (i.e. throwing a rod.) I hope in my case this did not happen or it will be the last Yamaha product I buy. I have owned several Yamaha sleds and have been pleased as punch to this point. However, this issue has me a little peeved. I hope things work out for me when I check the sled out on Saturday. I will keep you posted.

I meant to say oil tank is at its highest point

Contact MtnViper. He has the fix to the oil leaking out the vent problem.

The throttle bodies are tucked well up into the air box. If the sled were upside down and tipped to orient the motor much higher than the rear of the sled, the air box would still have to fill with oil before it could reach the intake - plus the sled would have to be running.
On its left side the oil tank is at the highest point. However, due to the placement of the tank vent port (which will also be at its highest point) only a relatively small amount of oil can run out. Any oil that did leak from a left-side down condition would just run out the air box intake ports and not rise to the level of the throttle bodies.
Hyrolocking from this mishap is pooh-pooh. Your non-starting problem is due to something else.
There's a combination tether and check valve setup sold by a TY member that can eliminate this worry altogether and by coincidence there’s a fresh posting to call your attention to it. At the very least, install a tether switch if you plan to go track up often.

Yeah, it would take time and alot of oil to fill the PTO culinder in that attitude.

Guys I was down a quart of oil when I checked and the sled was not running. The sled was on it's side for no longer than 4-7 mins. I hope the non starting problem is not something other than oil in the cylinders??? If it is what do you guys think it may be. When turned over the starter does not engage. Also thanks for the info on the check valve. I will 4 sure be buying one

When you turn the key to the run position does the pod light up and can you hear the fuel pump spool up? These would be indicators that you have some battery power and the kill switch is up.
In your first post you said it would not turn over. The post above says the starter does not engage; do you hear the starter run when turning the key? Any sound at all? If not, track down the starter relay and make sure it's not fogged from moisture and that it's seated in the socket. Make sure all relays are clear and properly seated while you're at it. Maybe water or snow rolled off the panel and into the relays while it is was rolled.
Anything else happen when you went track up? Any impact, all the panels stayed on, any wires get snagged when rolling back over?

Yes the gauge pod does light up and the fuel pump cycles I can hear that No kill switch issues either. However, when I try to start the sled it just makes almost clunk noise. I have not tried to do this too many times as I fear the cylinder has a large quantity of oil in it and I do not want to throw a rod.
The sled did not go totally track up. Just on it's left side. Not impact. The roll to it's side was slow motion but I could not stop it due to the angle of the ditch The panels stayed on and nothing got snagged. Moisture could be a possible culprit. I really want to pull the plugs and get the air box clean before I turn it over again.
Thanks

I have seen what hydrolock can do to a nytro. Was at my local Yamaha shop talking to the mecanic while he was changing the starter on a nytro that had hydrolock. They drained the cylinder and replaced the starter, and all was good. Untill the customer went out for his first ride, as a result of the hydrolock one of the rods was bent, and eventually snapped and made a big hole in the engineblock. He got a new engine on warranty.
Do not try to start the sled untill you are sure its not hydrolocked!
I certainly hope that you dont have this kind of damage!
