Very Odd Problemo

[400exrider989]

alright so my buddies 07 kfx has a problem, everytime he goes to start it it would fire up for a few seconds and then wouldnt run, he said it sounded weird and needed to be given throttle to stay running. so instintly i figured must be clogged jet, but he said no, he said after he tried to keep it running for a few seconds he checked the oil and he said it literally shot out of the hole, this has happend twice so far. my guess is that the oil filter may be clogged and be stopping oil from flowing or its wy to full and it couasing preasure inside the crank case, or a vapor lock type thing. the only thing he has done is changed the coolant to prevent corrosion

thanks for any help and sorry this is in both open and kfx section, its just i am fustrated and sick of this
