Is this a 103 -> 110 "conversion" by chance? If so, who's cylinders did you go with?
Just curious b/c I've done quite a few now with S&S' conversion kit and they're solid.

PS: You could examine the back side of the valves with a bore scope or pull the manifold
and pipes. That will help eliminate the possibility of it being a leaking guide/seal. (If it's not
that, I'd suspect the cylinders)

if it was all of a sudden,either broke ring or guide loose (guides coming loose is a fairly common problem with 110 heads),one would think it would be smoking a bit (or a lot) with either one though.one other thing you may want to look into is sumping,the oil out of the tank can be in the lower end,run it for a bit & drain the motor (not the tank,the plug on the bottom of the motor)

If the dipstick shows low (hot check), try letting the engine idle for five minutes and shut it off, then check the dipstick again.  If the oil level has increased significantly, the difference is the oil that was sitting in the sump instead of the oil pan.  A sudden increase in the amount of oil left in the sump on a Twin Cam is often caused by an oil pump scavenge side failing.

A bore scope would come in real handy when checking the other possibilities such as cylinder wall damage from a broken ring, or the intake and exhaust ports for signs of a valve guide issue.

Only a few ways the oil could be that low after 400 miles, and none of those ways are good.

Only thing that is certain is I need to get to a motorcycle drag race.
