It was fuel it was the cdi box changed it and runs fine now

I have a 2006 ltr 450 the starter is out on it but you can roll start it 2 days ago i rode it took a lil longer than normal to start but it started and rode just fine. Put it in the shed went to ride it tonite was even harder to start but finally got it started. When you go to hit the throttle it cuts out then it clears up and then would be fine if you bumped the throttle or was about half throttle. If you went full throttle it would bog down spit and sputter and the longer you did it would lose power gradually until it finally died. Any ideas on what it could be thanks in advance and this is my first 450 fuel injected quad

Need some help i have a 2001 400ex that smokes on start up and smokes even more when you give it throttle. I just noticed that it leaks oil at the header and motor connect. I just got it from a guy that said he rebuilt the top half and he told me that the valves needed to be adjusted. But what will make it leak? Thanks in advance
