My bike bike runs on main tank even on low somtimes shows some missing. I think my reserve tank doesn't work.Any suggestions?

Check the reserve fuel line and the main fuel line to make sure they haven't been switched. I purchased a Suzuki Intruder and was riding all the way to reserve to check the mileage and when I ran out I couldn't start it even though I switched to reserve. Turns out that someone had the tank off to service the air cleaner and had reversed the two fuel lines so the fuel valve was running the bike on the reserve tank tube. so when I switched to the reserve position it was hooked to the taller brass tube in the tank and the gas level was already below it. The tanks just have two brass tubes, one taller than another so gas cannot be sucked below the taller tube when on main and then when switched to reserve it sucks from the shorter tube allowing the remaining gas to be used.

Does a 2008 Harley super glide have a choke

This bike is fuel injected, therefore no manual choke. Choke or fuel enrichment in fuel injected terms is controlled by the ECM in conjunction with the engine temperature sensor. There is no 'reserve', but you will get a 'low fuel' warning light when fuel is low, same as cars.

Reserve fuel tank question...

Check that fuel valve, pull out that output fuel hose, turn the valve to "reserve", if fuel flows, that means it works( fuel valve ), if no fuel flows, that valve has STUCK valve flow.

Most bike problem is in that fuel valve.

Hope that helps!

On my 1994 fireblade which way should the fuel tap face for normal tank compared to reserve? my fuel tap is long at one end and short at the other but which end is normal for fuel?

Start with the fuel tap (called a petcock) in the horizontal position. This is pointing toward the back of the bike, and it is in the "off" position. Turning it counter-clockwise to point up is "on," and turning it clockwise to down is "reserve."

Normally, you'll want to run the bike with the petcock set to on, and save the reserve for the emergency situation when you run out of fuel.

Just got a trophy 3. dont know what position is which on the fuel tap? no markings.

Usually the fuel valve is this
Straight Down = ON
Straight Up = RESERVE
Horizontal/Across = OFF
There may be some difference with the manufacturers, or with custom fuel valves (chrome), also, fuel injected bikes usually do not have reserve or reserve position on fuel valve. If you have fuel injected bike, they do not like to be run out of gas, keep the gas level up.

Having a problem with fuel pump/fuel line if gas is put in gas tank it will not run to bike have to put it in a smaller fuel holder and then it goes straight to bike?

I'm not quite sure I understand your English. However these bikes' fuel supply operate on vacuum and if I understand correctly you're not getting fuel to the engine. Check firstly that the vacuum pipe connected to the fuel supply valve is working correctly. 3 pipes: 1 Main fuel supply. 2 Reserve fuel supply. 3 Vacuum.
Sucking on 3 will result in fuel pouring from 1 or 2 depending on where the valve is set.(Reserve or main). If not the valve is faulty.

What are the petcock positions on my 2003 bayou 250

There are three positions. Usually when the handle points to the rear of the bike the fuel is off. When the handle points down the fuel is on and will feed fuel until the reserve level is reached at which time the bike will stop running. When the lever is pointing toward the front of the bike it is on reserve and it will start and run until the bike is completely out of fuel. If you run on reserve to get to a source of fuel remember to put the lever straight down or next time you will not have a reserve. When the bike is parked the lever should always be in the off position.

Where is the reserve tank

Is your bike fuel injected or carbureted? If it is fuel injected the tank has a 4.5 gallon tank and that's it. If it is carbureted the fuel petcock is a three position valve (ON, OFF, RES), the valve is configured in the tank where ON allows fuel to flow until you are down to about 1/2 a gallon at which time you would turn the petcock to RES which allows the engine to use the last 1/2 gallon of fuel and gives you time to hunt down a gas station.

There is no separate "reserve" fuel tank.

Fuel Reserve switch

Typically there are three positions to choose from. On means you are using the main tank. Reserve means reserve tank and off means no fuel available from either tank. the off setting is used when trailering your bike.

How to refill the reserve gas tank 1981 Honda CX500 motorcycle

there is only one tank to fill on your bike, your getting confused by the reserve. The reserve is just on the fuel tap itself. It has three positions, on , off and reserve. In the on position your fuel tap will be able to drink about 90% of your fuel tank and then it wont be able to drain anymore, then you must turn your fuel tap to the reserve position and it will be able to drink rest of your tank approx 10% that is left. So next time you fill up at a petrol station make sure your fuel tap is set to on, then when your bike starts to splutter out of fuel you can turn your fuel tap to reserve and get yourself to the petrol station to fill up, making sure you then turn your tap to on again. If you keep running out on the reserve it can cause debris in your tank to clog your carb up.
hope this helps
