dirt bike help... got 2 problems HELP ME PLEASE

what can be causing my dirt bike to want to keep pulling and revving when im in gear. its like it idles well, but when i get going it doesnt want to slow down, it still wants to pull although i am not on the throttle. the throttle isnt getting stuck though because when i go up to the next gear the motor calms down and let me control it again

could it be because i have a broken stud in the cases which lets the cylinder leak


another problem the bike gives me now is it now throws oil out where the exhaust hooks to the cylinder could this mean that i need another top end. top end on it has 5hrs max on it since rebuild.

what can i do to stop these problems

the bikes is a old 78 Yamaha YZ400
