Hello, i recently just put a new cluch plate kit on my blaster, and a new oil seal behind the sprocket. Now when i start it up its burning tranny oil. I never even took the clutch basket off and am stumped why it os doing this. Any help would be greatly appreciated.
Need help engine burning tranny oil

How much oil did you put back in it when you put it back together?
It only calls for 650 mL or about 2/3 of a quart. Was your engine idling way up when it got warm before?
That's an indication of an airleak which would also explain the drinking transmission oil....

I put exactly 650ml in. It is very hard tp start, and when it does i have to hold it wide open to keep it running. I used 10w-30 synthetic, what the manual calls for. Also i noticed when i put the clutch in the first 2 plates by the basket wouldnt move when i pulled the lever, would that have something to do with iy?
You need to build or buy a leakdown tester. Member slickerthanyou sells them really reasonably priced.
Basically, you pressurize the engine to ~7psi and see if there is any air leaking. I have a sneaking suspicion that you won't even be able to get it to 7psi, with the symptoms you are describing.
you need to do what civic said! get a leakdown tester and test the motor for airleaks. you probably already had the leak before the clutch replacement just got worse
Good news is, it's VERY unlikely that anything you did involving the clutch or output shaft seal had anything to do with this. The only thing you "did" was fill it back up with the proper amount of transmission fluid which allowed a hole in the cases or leaking clutch side seal to begin sucking in that fluid.
Buy or build yourself a leakdown tester and find your air leak. I would start with the clutch side crank seal.

learn it's not that hard to remove the carb and exhaust. then do the test. if you can do the clutch you can do this
you spray soapy water on the engine and where it bubbles is where the leak is. best to pull the clutch cover for the test
The leakdown tester installs into the carburetor boot after sealing up the exhaust port hole. You then pressurize the engine to ~7psi and use a soap solution to pin point the leak. Because air will be squeezing out of the engine only, you will be able to see wherever the soap solution bubbles, there's the leak.
But its definently a seal though? So weird cause it ran perfect before i did the clutch, it was just slippong.
can't be 100% it is the seal. but that is the most likely culprit. and like civic said. before you were just sucking air bc your oil level was probably too low to suck oil. sucking air will blow your motor faster than anything. you need to address this problem and stop worrying about why or how it happened
The seal only has to leak a little to allow unwanted air into the crankcase, this will lean out the fuel mix.
A small air leak will make a leaner than normal mix and the motor may seem to perform very well but may overheat and damage the piston.
Fill the oil to the correct level and it will be pulled into the crankcase and burnt.
