Question about Motorcycles
Hi Butc, yes you should hear the fuel pump I would check the pump relay first and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of over use of enrichner.
5. Vacuum hose to fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, loose, corroded or broken battery terminal connections especially the "NEGATIVE" cable inside the harness at both ends.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to faulty ignition coil, ignition module or sensors (MAP, CMP CKP and/or BAS).
11. Sticky or damaged valve or pushrod wrong length.
12. Primary cam sprocket spline sheared or missing spacer.
13. Security alarm needs a reset.

You have a couple of electrical checks you can do first. Yes this will be somewhat painful. The other item is if you go through these troubleshooting steps you won't be happy if your fuel pumps DOA.
First replace your fuse, I know it may look good, but replace it anyway. Next check your relays, then under your speedo console there is a connector on the tank. If this connector has been unplugged it is very easy to bend the pins inside, check for that. Check for power to the pins. If you have power and still no working pump, then it is an entirely different task and somewhat costly.
A bad fuel pump is not a real fun replacement sometimes it is however not a bad idea to replace the whole ball of wax which can run you about $400 for parts at retail. If you conclude your pump is bad just post with your year and model. Hope this helps,

Sometimes there is adaquate pressure and we don't hear the pump, but it does pump while crank and running. A couple of things here, one is the fuel filter, etc. and battery. You did not say how many miles are on the bie, somethings like the fuel filter are usually replaced based on mileage; while depending whee you are 3 years on a battery is about all you can expect.
The reasons why the bike dies can be many, especially at low RPM or idle. Check your air filter, replace if needed. Change your plugs if they are questionable. Change your fuel filter if you have 40K miles on the bike. Unfortunately you could have a range of sensors that are "tired" or about to go bad if the problem persist. The easiest thing to do is take to your dealer if after changing plugs, fuel filter, and air cleaner doesn't help. The dealer will hace the specialty tools to test the sensors and other components that may be in question. Usually they can determine what needs to be done in less than an hour.
Hope this helps.

Ride the bike until it starts "holding back" or whatever it does. If you think it's fuel level related. Disconnect the fuel line at either the carb or the tank. Turn the fuel on, or if you have one of those vacuum operated petcocks, apply vacuum with a hand operated vacuum pump to open the petcock and test the fuel flow. See if you have a full stream of fuel coming out of the hose. Then fill the tank, and retest. Notice the difference in the flow.
Now, if there is a noticable difference, what is causing it. It could be the petcock screen. I've seen the screens have a "too high" standing pipe for the main fuel supply. The screen has a "pipe" made into it that is usually about an inch above the petcock. Fuel flows down this pipe when the petcock in the "ON" position. When the fuel level in the tank falls below the height of this pipe, the engine sputters and sometimes stalls indicating that you need fuel. But, when you switch the petcock to "RES", another hole in the petcock, which does not have the standing pipe, will open up and allow you to use the remaining fuel in the tank. On a Sporty, this is usually somewhere around a gallon of fuel or about 40 miles or so.
One other thing that could be effecting this the level of the bike. If they has been lowered this could have altered the "level" of the bike. On a Sporty with it's small capacity tank and the shape of the tank, if the has been lower by as little as 1" in the rear, it will cause a problem such as this.
I notice that the bike is a 2010 model. If it's still under warranty, take it back to the dealer and let them figure it out. That's what a warranty is for. But, just in case, keep this things I've mentioned in mind.
