My buddies 97 600 sx used almost a whole tank of oil for one tank of gas while riding this weekend. The other 97 Sx 600 in our group didn't go through near that much. The oil pump was replaced before by the prior owner due to similar problems. The pump on the sled only has 3 months use on it. I know it was replaced because he sent the old pump with. maybe it just needs to be set? i noticed two tick marks engraved in the pump housing and one on the acuall lever connected to the cable. how do you set this up??
