Fixing/modifying a 2008 Heritage softail. The bike had front end damage and probably lying down for a while. The engine oil reservoir was empty. I drained all the oil from the bottom. Prob a quart came out. I put 3.5 quarts of synthetic. Also changed all other oils. Painted the bike, replaced front end etc etc. The bike was on a stand all this time straight. After marrying the TSM, I started the bike, it started and was running fine. After two minutes the engine oil reservoir cap flew and oil splashed all over the place. It was overflowing and seemed kinda dirty and frothy. Where did all this come from? I drained 3/4 of a quart started it again and after one minute the level in the reservoir started to rise again to reach the top. I shut it off and wan to know experts opinion.

 

Mod please delete this. my bad. I posted twice. Got my answer in the softail forum.
