I just finished putting a new tranny in my 01 raptor but I'm having trouble getting oil pressure . I put a qrt in the oil tank and some down the threw the top of the head and I cant get any to come threw the oil line in the top of the head. and there was very little in the oil filter . Is there a proper way to get the oil to prime? air pressure threw the oil tank or putting oil down the oil tube? my be I will have to pull the clutch cover and check the oil pump gear.
