How much gas does your V Star 650 use before you need to switch to reserve?

How much gas can you use with the pepcock at on? It seems I can only consume 2.8 gallons, even though the tank is supposed to be 4.2

The only think I can think up is maybe I'm not filling the tank as much as I think I am.

I was going down the road and the throttle became unresponsive in the same way it does if I drive down the road with the pepcock off by accident. I only rode 138 since last fillup. Fortunately I was close to a gas station and was able to coast up to a pump.

I didn't try using the reserve.

What position is the long tab in (up or down) normally when you ride? The reserve should work, but if you're riding with reserve on then you have no backup when you run out.

No, I ride with it down. I just didn't try to turn it to reserve cause there was a gas station right there.

I'm thinking I'm not filling the tank all the way up. If the reserve is designed to hold back .7 gallons, it should have been able to put 3.5 in it instead of only 2.8.

I've been refilling every 100 miles and it has been taking almost exactly two gallons. I thought 50 miles per gallon seemed to good to be true, but I just didn't know. I just hit 600 while I was riding today. This is my first bike.

V Star 650. I just expected to consume about 3.5 gallons before the main line ran out. I just open the gas cap. Even after riding 15 miles since filling it up, it still looks filled to the brim.

I get from 155 to 165 on the 3.44 gal and this is over 42,000 miles.
also you should flip it to reserve every few tank to remove any condition that may be in there.

I have just about every fill up since I bought my 650 last August.

I tend to fill up a bit after I switch to reserve. I'm usually at 150-170 when I switch to reserve. When i'm good I usually can routinely hit 168 as my reserve is needed. I can hit 200 while on reserve, but I'm usually near enough to a gas station, I had to push one time since I really was testing it.

I have had as little as 35mpg in a 20 mile per hour head wind.

You probably already know this, but just for fun...
There is no true "reserve tank" on the 650.
There are only two pipes in the same tank. Those pipes are different lengths, so when the level of the gas drops below the upper end of the "main" pipe, the "reserve" pipe is still submerged and can suck most of the remaining gas into the petcock and on to the carb. I average about 54mpg.
BTW, I've found that a lot of systems in a lot of bikes are not set accurately. I've only got about 3 miles when I switch to reserve after damn near starving it into stalling on the main. I'll eventually take the thing apart, clean it and find out how I can adjust the height of the tubes, but in the mean-time, I'm terribly anal about filling up no later than 168 miles.
