Ah, yes. This subject and endless discussions of it cannot be found on the forum . . . In most of this great land of ours, the rule on the streets is that, if an intersection is controlled by a light, you obey the light. At stop signs, generally, whoever arrives first has the right of way. If in doubt, yield to traffic from the right.
Follow those rules at four way stops, and you will likely encounter very few problems. The size and/or speed of vehicles relative to one another has little to do with right of way.
Of course, being among the lightest and slowest of vehicles on the road, it behooves you to make certain that other traffic is actually aware of and willing to yield to you when it is your turn. You don't want "he had to right of way" to become your epitaph.
Of course, the bible-thumpers in this "community" will go on about how stop means stop - foot down and all. Follow that wrote advice if you choose - it will not necessarily make you a safer rider. There are many times while encountering a stop sign when the safest move on my part is to keep moving and be clear of the area before oncoming traffic arrives. . . but you will actually find posts in this forum where riders are advised not even to accept a driver's offer to yield when offered because of possible legal "consequences" should an accident (god only knows of what sort) occur.
I think you already know from experience the inherent risks of your method of handling four-way stops.
Use your head and you'll be fine.
