Thanks: PS: My bike looks a lot like yours.It certainly doesn't hurt to occasionally run on reserve. Even though there's only a tiny bit of fuel kinda "stuck" in the reserve valve, there's also a tiny but of micro particles -- dust, dirt, etc. -- stuck in there as well. Letting fresh fuel run through the reserve valve for a bit will prevent any build up.
By design, the fuel valve assembly sits above the absolute bottom of the tank. That way most dirt, dust, etc. that inevitably enters the tank ends up settling below the fuel valve assembly. The ensuing sludge will eventually need to be cleaned out. The good news is that it takes years for any significant amount of sludge to build up.
It's an archaic system, but it works pretty well!
I gotta laugh with reading this post @gdb069A good practice is to occasionally reach down and switch to reserve and then back. This ensures you know how to do it without looking if you do run out of fuel plus it helps keep the valve in good order. I do it about 2 - 3 times a season.
That's pretty much what I do but being in town makes it a lot harder. I have had from 32-45 mpg depending on my driving, traffic, stops, etc. I hate that I can't look into the Honda tank and see the fuel. In my other bikes I can tell how much is in the tank by a quick glance if I haven't paid enough attention to the mileage.Back when I had bikes that had reserve, I would run till I needed reserve, record the trip meter reading, then go gas up. This way I would know the tank mileage then run it completely dry and record that mileage. Then you know how far approximately how far you can push it.

Mine doesn't get as good gas mileage (modded 750 ACE) and it varies depending on how hard I push it (35mpg to 50mpg, US gallon) I run with the petcock on until it complains and switch to reserve. It doesn't just instantly die and have no qualms switching in any traffic situation. Not having reserve and a bone dry tank is too scary a game for me.I ride with the reserve valve open at all times and reset the trip meter every time I gas up . I do not want to have the bike quit out on the road without warning and have to switch to reserve possibly in a poor traffic situation. I usually fill up no later than 200 miles. I normally leave for a ride with a full tank.
I also reset trip meter every fill but why not just ride with fuel valve ON and reset trip meter. You may have to refuel at 180 miles. That way you will always have a little reserve. To me it just doesnt make sense to be out of fuel "possibly in a poor traffic situation" when you can simply switch to reserve. PS there is some warning that you are running low on fuel since the fuel is sloshing around a bit so you will notice a lack of acceleration and maybe slowing a bit providing adequate time to change to Reserve.I ride with the reserve valve open at all times and reset the trip meter every time I gas up .
