burning oil when bike is at operating temp!!

[Doctorshred]

I bought the bike as "salvage" it was in a fire, and had burnt enough to melt most of the wiring, and the carb a little. I slapped on a new S&S super E carb, and re wired it long story short thing runs great with plenty of power.
I have been running Castrol 20/50 non synthetic oil with a couple of oz. of "Lucas Oil Stabilizer" in my crank case. I have always used Lucas in my hot rod chevy's, but I am beginning to question it in these v twins. Also are these older fxr's just prone to burning a little oil when there hot with high millage? Could the fire have damaged something internally to make it smoke like this? It runs great by the way, and is fast as hell with no backfires, or misses one so ever. I even get the back tire to break loose in second when I am hammering on the gas, so performance wise It seems fine with no lack of horsepower one so ever...
If you have any ideas please let me know.... Or if Lucas is a bad idea for an evo please let me know that as well. I hear "Amsoil" is the way to go what do you guys think.
Thanks for your time....

What is your compression? How much oil are you losing? Are you sure your burning it and not losing it someplace else?
