no oil in crankcase

I have a 2007 400ex and performed a oil and filter change on it and over filled it with 2 full quarts.. When I check the crankcase oil check bolt nothing comes out like there is no oil in there and the manual says fill the resevoir if no oil comes out but the oil resevoir is already overfilled like coming out the cap overfilled?? So what do you think the issue is? I fear of burning up my engine if oil is not getting to it!!! Please Help Thank you

This might sound like a dumb question, but just to make sure are you checking the right place? There should be a dipstick on the right side of the crankcase to check the oil level, not a bolt.

Place the vehicle on level ground. Start the engine and let it idle for 5 minutes. If the air temperature is below 100e (50F), let the engine idle for an additional 5 minutes (a total of 10 minutes). Stop the engine. Remove the oil filler cap/dipstick from the oil tank and wipe it clean. Check the oil level by inserting the filler cap/dipstick into the filler hole without screwing it in.
The engine contains a sufficient amount of oil if the oil level is between the upper and lower level marks on the dipstick. If the oil level is near or below the lower level mark, add the recommended engine oil up to the upper level mark.

You only need to use the bolt check if you have reason to suspect the oil pump isn't working. If you remove that bolt the oil should be at the bottom of the hole, meaning oil won't necessarily drip out

There, guess it wasn't a dumb question because I learned something new. Unlike my trx300, a 400ex has a dry sump engine. Please excuse me while I go learn some more about dry sump engines...

I have been checking the oil the proper way but I have relized when I changed the oil I drained the cranckcase with the check bolt not the proper drain bolt on the other side oops. So there is alot of undrained oil proably would'nt you think? with the full 2 quarts I added there is way to much oil in my quad could I have done any damage to the engine with to much oil? I will drain some oil from the resevoir and that shoud get things back to normal I would think or should I drain a little from the proper crankcase drain bolt? I still dont understand why there is nothing coming out of the crankcase check bolt with too much oil in the quad it's like it's not getting there that worries me? Thanks for any help.

I would think it would regulate itself and keep any extra oil in the tank and not in the crankcase.

You were supposed to add about 1/2 quart through the top of the engine.... you need to remove the 10 mm bolt under the oil lines and pour oil into the top of the engine until it starts to run out of that hole. Put the body back in. Then you can top off the tank.
