pulled all fuses all fine
checked all conn al tight
installed a new main fuse
turned the ignition on the dashboard

No.... Don't have a place/tools/or
the time a local independent mech
will be but if I could point him
in the right direction before he gets to
deep might make it easier on him and my pocket

OK...I'm gonna theroize this problem with the information you provided.
Unplug the regulator module and test again.
I did review the power distribution system schematic.Every line that comes from switched ignition is fused below the 30 amp.If the 30 amp main fuse is blowing its from a short tied to the switched ignition line and not from any external parts.
eg..If the radio were bad it would blow its fuse.All the other fuses are ok.
The regulator ties directly to the 30 amp fuse and is activated or enabled by switched ignition.
This is assuming the bike is OEM wiring and there's no additional equipment been added to increase the load from the 30 amp fuse.
As I recall,with the engine not running,the bike draws around 15 amp from the battery with the key,lights and ignition on.
Should there be a problem in the regulator module,when its energized,it may add to that load enough to blow the fuse.
