1986 FJ1200 Spews Oil from Crankcase Breather Hose

. so oil meter may be off but after dropping oil+filter i was putting the right cc's according to manuel,

You can't blindly trust the amount specified in the manual.  You MUST check it at the siteglass.

Here's what I do to ensure my oil level is correct for an oil and filter change. 
Pour in about 3.5 quarts.
Start engine and let it idle for about 2 minutes to distribute oil and fill up filter.
Shut engine off and let it sit on the sidestand for about 15 minutes to let the oil drain back into the sump.
Put bike and centerstand and top off oil level to top of siteglass window.

If you don't put it on the sidestand to drain back, you'll end up putting too much oil in.

Hi, it seems you have checked all that I would, are you sure the breather to the air filter box is not blocked creating engine back pressure?
