I'm attaching a picture.. After a long weekend of riding, I have oil coming from my head gasket in 1 cylinder. My sled only has 1200 miles on it. Any idea why it might be doing this?

looks like your manifold gasket is leaking

yup, thats oil blowing straight up from exhaust. A leak in the head gasket would leak coolant.

2 strokes only have coolant under the head gasket, no oil. That's your manifold gasket like others said.

Oh okay. Well could not enough back pressure cause this? Because I made a homemade can last weekend due to my factory can rusting out. I just made a 4" can so I could ride this weekend but I didn't put anything inside the can to baffle it. Yesterday I cut out two, 4 inch circle plates and drilled holes in them and I'm going to weld them about an inch apart from each other inside the can to help baffle it and create back pressure.
If so, do you guys think my motor is in bad shape now or do you think it's just a gasket? I rode about 62 miles this weekend with my homemade can. I just don't have the money right now to spend 300$ on an aftermarket one..

Remove exhaust manifold and clean the gasket thoroughly. Dust with copper coat 2 or 3 times. Leave time to dry and flash over between coats. If you don't want to wait. Warm it up on the shop heater. Once to copper coat touches the surface it drys instantly.
The plug on that cylinder might look abit different than the others.

The other thing is, it ran great all day Sunday. When I loaded it on the trailer and brought it home. I went to pull it off and it wouldn't start. Eventually I got it to start and it sounded like it was running on 1 cylinder and didn't have enough power to move. I shut it off and pushed it inside. Then I let it sit for 3 hours and then tried starting it again. It fired up the first pull and runs fine. Idk if it flooded itself somehow and if that has anything to do with the oil. I'm guessing it does because the motor was spotless of oil and stuff before this

Easy fix as described above by couple of bucks for exhaust. A new gastket all together is cheap enough. Trailering will flood engine from time to time with all the bouncing and such. If you dont have one install a simple gas shut off valve, and that will prevent this from happening. Also you dont need a aftermarket can, unless thats what your after. The power gain is minimal if any and are just noise makers IMO, infact most cans decrease power just not sure on your model. You can post a want add here and pick up a stock can for cheap im sure.

That's what it looks like when you have an antifreeze leak on your head gasket.
