Default No compression

Went to start my 1984 flh after sitting for a few weeks, puked oil out the breather like it always doe's after sitting, then it started on one cylinder and quit. Tryed to restart and it shot the dip stick out of the oil tank and sounded different when it was turning over. Checked compression and have none in front cylinder and 15 in rear. Any ideas ?

Thanks Scott

Turned it over with both sparkplugs out and it's still shooting the dipstick out of the tank.

Pushrods are going up and down. Had the issue with the dipstick shooting out back in march. Did it a few times at start up and then it was fine . Quit doing it after about a week.

If the bike was running fine before it sat for a few weeks, then about the only thing that would give you 0 compression with the pushrods moving is going to be stuck valves...how many weeks is a few?

About 4. Was running good before that. Had it down to put a "Big Cert" in rear plug hole.

try a different compression gage before moving foward

if the readings are more normal in the readings than replace the plugs

having both cylinders like that and no running issues last time riding something else is going on
