About 95% of us do if not more. time for a poll? lol.
Actually good advice for all motors, vary the throttle the first few hours of use.

I personally am not 100% for the whole break in period. I believe that you should mix the gas but I also believe in you should break the sled in how you are going to ride it which means if you are going to be going wide open go wide open. What has me convinced on this is studies that the engineering university that I go to has done. Bassically the studies show that the engine will wear in properly if you ride it how you are going to. not everything is going to seat properly if you dont go wide open and you are going to be riding that way often.

its not BROKE IN til its BROKEN!
Still don't understand the exact reason for mixing the first tank of gas with oil.
Makes about as much sense as taking a new motor apart before you run it, you never know they could have put it together wrong at the factory, so just to be on the safe side you know.
If everything is right to start with there is no need to mix the gas with oil. On your machine you have a oil tank and a gas tank and thats pretty much all that should be in either of them.

Wrong!!!!!!!!!! The extra oil is to prevent a melt down if your brand new oil pump is not working from the get go. Also the extra oil in a Poo helps the rings seat a bit better. I ride them hard right out of the crate and do not have issues ever. I had babied a new 2000 700 xcsp back in the day did the entire break in thing, and that motor was a turd. I firmly believe in preventive mantainance (walking out of the woods at night all alone really sucks). But that was for running out of gas.
X2 for what Wintertime said.
Ok, so if your oil pump isn't working out of the box, and you premix a tank, what happens on the second tank? BOOM.
I agree, and so will Mike on the running it hard from the get go to create cylinder pressure to seat the rings, but extra oil has nothing to do with it.

Perhaps it's because that is what the Mfg wants as an added measure of protection. Many an engine ruined fresh out of the box without the extra oil, due to the fact that some like to grab a handful of throttle before the engine is at a reasonable operating temp, then, bam! Cold piston seizure. That could be a matter of Warranty or No Warranty.-Mezz
But then again, is that due to a lack of oil?
The window of opportunity for ring seat is pretty small on any new/rebuilt motor. No matter what you do after that window is closed the rings are what they are and theres no going back (unless you hone the cylinder and install a new set of rings).
The additional oil will only stop/prevent ring seat.
But then again, if the rings don't seat on a two stroke motor whats the worst thing that could happen? It will burn oil? Oh wait, they do that all the time anyway and there's no crankcase breather so you'll never know just how good the rings are seated.
So, carry on.

Oil or lack of oil has little to do with cold seizures. Cold seizures happen because of different metals expanding at different rates. Your pistons are aluminum and your bores are nicasil. Your rings are steel. If it is 10 degrees when you start it up and operating temp at the top of the piston is is 1300 degrees you have a lot of expanding to do by all parties concerned. It is common for large bore twin 2 smokes like 800s to have scuffs and scores on the pistons after the first 10 minutes of operation. Minor scuffing and scoring will have a minimal effect on engine life or operation. The single most important thing a person can do while breaking in anything is to properly warm it up before you hold it wide open. It is a good habit to get into even after the break in period is over.
You don't check the the oil when you fill up with gas?? I guess you might go boom.
Two week trip in Canada (remote area) with new sleds. At first fill up buddy noticed oil had not moved. Added oil at each fill up, pain in ***, but better than sitting in a cabin with no TV for two weeks.
I always started the season with the first tank with premix.

Thank you! great answer.

The primary reason for premixing the first tank is to ensure that there are no air bubbles in the oil injection system which prevent the proper amount of oil to reach all parts necessary and to make sure that the oil pump is working properly. I personally believe in running a little bit of oil in my gas tank even after break in. I would rather foul a plug than an engine.
