Anyone know the front/rear wheel weight distribution for a Tourer?

I have a small trailer that I use for two dirt bikes loaded side-by-side.  The trailer deck is barely long enough to support the back tires.  I want to add a wheel chock on the tongue to haul a street bike if I need to. I figure my Tourer is the heaviest bike I will ever want to haul on this little trailer, and I want to get the weight distribution right for tongue weight, thus my question in the subject line.  I can mount a steel channel so the Valk’s rear tire can overhang the deck, if needed.

The rough estimate is 10 percent of the total trailer weight should be on the tongue. The tourer is about 750 + trailer (250), therefore 100 lb on tongue.

I know this. I want to know the motorcycle’s weight distribution on ITS wheels so I know how forward to place it on the trailer.

Got a farm supply store nearby? They may have a scale that goes up to >400 pounds that you can ask to roll the front wheel onto.
Standard curb weight is 769#, so if it's 50/50, 385# on the front wheel alone. You can do the math from the actual reading.
