When I hold my 200DX at full throttle, Oil seems to be coming from top of the head under the gas tank, I don't believe this problem started until I over filled it with oil. One person said it may be the Valve Adjustment, if so would this also explain the lack of idle. I have tried adjusting the Carb. (Just to let you know a 200DX is a four stroke, the predecessor to the Timberwolf) I usually take all my bikes to the dealer but I believe this could be a minor problem. Thank you guys for your help.

 

This seams to be a common problm on this board..
Take the plastics off and remove the gas tank. Then retouque all the top head bolts. Unlike your bike MY race bike was designed to blow oil from the top. I have a breather hose connected to a res bottle that drains off. Good luck with you oil leak. ATV's Don't Leak They Just Mark Their Territory!

 

If you put too much oil in, the motor probably built alot of pressure and either blew a seal or gasket or it could have cracked the head if you really filled it up but most likely a seal or gasket
