good afternoon
After running my BF5 across the lake yesterday I noticed a little oil under the head unit, only at WOT for about 2 min it started to spray. not leaking at any other RPM range. Engine runs great and always starts first or second pull. After investigating I figured out it was coming from the crank case breather tube. Checked oil and I must have over filled it because it was a little over the full line. Checked compression its with in spec. Removed fly and pulled the crankcase breather apart , diaphragm and filter looks to be in good shape. I will put new oil in and only fill to half way between min and full mark. I am checking the oil level with dip stick in but screw down. Is there anything else i should check? has anyone herd of this problem before?
Thanks everyone!
