So I was walking to my bike with this really cute girl in my class and I got on the bike and started it up. Reved it a couple of times to show off infront of her than it cut off (Guess that wasn't so smooth to do). Than I was like okay, let me switch to reserve. So I switch to reserve and it cranked up but than cut right back off like I didn't have gas in the reserve tank. Than the cute girl from my class pulled up next to me and was like are you okay?....So after a couple of seconds being on the reserve tank. It fired right back up and went to the gas station to get gas.
I guess bikers whos bikes run out of gas isn't getting the ladies now of days lol
But that's why I asked if it was seperate tanks to fill up because I just thought my reserve tank was empty when I switched over.

The trick is to either watch your mileage and estimate whenever you need to switch to reserve, or when the bike starts to hesitate switch immediately before you run the carbs dry. If the carbs run dry, you will get the behavior you are speaking of where it takes a bit of coaxing to get the bike running again.
You may already know this, but you seem like a new rider by the question you asked, so here is my advice:
1) Fill the bike up to the neck of the tank with gas, make sure you reset the trip odometer
2) Ride the bike as you normally would, but once you get about 130 miles on the tank, stop, record the mileage on the trip odometer, reset it, then refill the tank.
3) Write down on the gas receipt the mileage from the trip odometer. Use the gallons purchased and the mileage to determine your fuel economy (mileage ridden/gallons purchased)
Say you had 135 miles on the tank, and bought 3.25 gallons of fuel to fill the tank back to where it was before (135/3.25)= 41.5mpg
Use that knowledge, with the knowledge of how many gallons you have before reserve to estimate the range you can go before you need to switch to reserve. 41.5mpg * 3.7 until reserve = 153.55 miles
In the above example, I would be safe and switch around 140 miles, and start looking for a station.
Note your fuel economy will depend on a lot of factors, so don't measure once and think that number will not change. The following will affect fuel economy:
-Whacking the throttle either while moving or just revving it hard while stopped (more fuel used)
-Higher sustained speeds = more fuel used
-Tuning of the bike - poorly tuned, less fuel economy
-Jet kit/shimmed carb needles = richen the mixture, more fuel used
-Letting the bike idle for longer periods of time, or sitting in traffic a lot (fuel is still being burned, but no miles show on odo since bike is sitting still)
-Altitude = bike may run richer at higher elevations since the air is thinner
-Headwind = less fuel economy, more RPMs required to compensate
-Gear/luggage/passenger = more weight, generally the worse the fuel mileage
All of this may seem like common sense (and it really is), but knowing these things can mean the difference between pushing a bike and being able to ride it to a gas station.
Consider these two situations:
Last year coming back from Indy I was on the interstate and was pushing the edge of my reserve, and when I pulled off I found all the stations were out of gas (hurricane supposedly disrupted supply), so I had to ride about 30 more miles to get to a station. Lesson learned there - you never know so don't push your luck...
Riding the Blue Ridge Parkway, there are *no* gas stations along the parkway, and many of the exits are for access to small towns that may only have one station that may or may not be open. Again, it is best to know these things and plan fuel stops and not assume anything, else you may find yourself walking. Know your route, and plan accordingly for gas stops.
If you are on reserve and the bike dies again, you can sometimes rock the bike from side to side and free up a small amount of gas that is not accessible to the pickup 'straw'. This varies by bike. I own a KLR650 and I have had to do this because I let the bike tip over in the yard, and failed to estimate the amount of gas that poured out. If you can rock the bike and hear sloshing, there is a slight chance you can get the gas to the pickup and ride a few more miles.
