What You'll Learn
The Kawasaki VN750 has a fuel capacity of 3.6 gallons
Another user reports that they average 120 to 130 miles before switching to reserve. They also mention that their fuel gauge doesn't work, and from what they've heard, it's not worth fixing. Instead, they rely on their trip meter to keep track of their mileage.
Some users have discussed the idea of occasionally running the bike on reserve to clean out any water deposits or stale gas in the reserve system. However, others have pointed out that this may not be necessary, as the fuel is mixed when fresh fuel is added. Additionally, running the bike on reserve may result in more crap in the reserve side filter screen.
The Kawasaki VN750's fuel capacity of 3.6 gallons provides a good range for riders, and the bike's fuel economy contributes to its efficiency.

The gas tank is considered small
The Kawasaki VN750 is said to have a fuel tank capacity of 3.6 gallons. However, some users have reported that their fuel gauge reads empty at around 2.6-2.7 gallons. While this capacity may be sufficient for some riders, others have noted that the gas tank on the VN750 is considered small.
The perception of the gas tank being small may be due to a combination of factors. Firstly, the distance one can travel on a full tank depends on various conditions such as riding style, speed, terrain, and even the rider's weight. For example, at higher speeds above 55 mph, the mileage decreases significantly. One rider reported getting only 30 mpg while riding steadily at 85 mph on the interstate.
Additionally, the reserve fuel system on the VN750 can be a factor in the perception of a small gas tank. The reserve fuel is not a separate tank but rather the last bit of fuel in the bottom of the main tank. Some riders have shared their experiences of running out of fuel or having to switch to reserve after covering distances of around 100-150 miles. This relatively shorter range compared to other vehicles may contribute to the perception of a small gas tank.
Furthermore, the accuracy of the fuel gauge has been questioned by some VN750 owners. Some have mentioned that their gauge is not precise, leading to uncertainty about the actual fuel level and range. This uncertainty may prompt riders to play it safe and refuel sooner, which could contribute to the perception of a small gas tank.
The small gas tank perception has sparked discussions among VN750 owners about potential modifications. Some have expressed interest in installing larger fuel tanks, with one rider mentioning a 5-gallon tank installation. However, these modifications may not be feasible or desirable for all owners, and the small gas tank remains a consideration for VN750 riders.

The fuel gauge is not accurate
The Kawasaki VN750 is said to have a fuel tank capacity of 3.6 gallons. However, some users have noticed that the fuel gauge is not always accurate. In some cases, the gauge may read empty when there is still fuel in the tank. For example, one user reported that their gauge read absolutely empty at 2.7 gallons, leading them to believe that the actual capacity was only 2.7 gallons.
There could be several reasons why a fuel gauge is not accurate. One possibility is that the fuel level sensor is not working properly. This sensor is located inside the fuel tank and uses a float arm and wiper assembly to measure the fuel level. If the sensor is not working correctly, it can cause the gauge to give inaccurate readings.
Another potential issue could be with the wiring or connections to the fuel gauge. For example, if the connector to the fuel gauge is loose or disconnected, it can cause the gauge to malfunction. In some cases, corrosion or a faulty connection between the male and female plugs could be the issue.
To troubleshoot a faulty fuel gauge, there are several tests that can be performed. One test is to stick a wire between the two female plugs on the bike for the fuel sensor. If the gas gauge responds by moving, then the problem is likely with the fuel level sensor. Another test is to pull apart the 2-wire plug assembly on the front right side of the speedo assembly and use needle-nose pliers to short out the pins away from the assembly. If the fuel level needle moves, then the speedo assembly is likely functioning correctly.
It is important to note that the fuel gauge on the VN750 may not show more fuel once the petcock is thrown to reserve. Therefore, it is recommended to keep your speed down to easily go 150 miles on a tank. Additionally, some users have reported better fuel mileage when using synthetic motor oil and/or switching to iridium spark plugs.

Mileage depends on driving conditions
The Kawasaki VN750 is said to have a fuel tank capacity of 3.6 gallons. However, some users have reported that their fuel gauge reads empty at around 2.6-2.7 gallons. The bike's small gas tank and varying mileage make it challenging to determine how much fuel it can hold.
One user reported getting 64 MPG when riding at highway speeds of 70-75 MPH. However, another user experienced a decrease in mileage once the tach exceeded 4,000 RPM. Riding at a steady speed of 45 MPH on the Blue Ridge Parkway, they achieved over 60 MPG. At higher speeds of 85 MPH, the mileage dropped to around 30 MPG.
The Kawasaki VN750's fuel efficiency is also impacted by the type of fuel used. Some users have reported improved mileage when using regular fuel instead of high octane gasoline. Additionally, synthetic motor oil and iridium spark plugs are claimed to enhance fuel mileage, although these have not been verified by all users.
The accuracy of the fuel gauge on the Kawasaki VN750 has been questioned by some users, who have found it to be inconsistent or unreliable. This has led to concerns about running out of fuel, especially during long-distance rides or in remote areas with limited access to gas stations.
To maximize mileage, some riders suggest maintaining speeds below 55 MPH and keeping RPMs low. However, others emphasize that the Kawasaki VN750 is built for highway speeds and encourage riding at faster paces when fuel stops are readily available.
In conclusion, the Kawasaki VN750's mileage is influenced by various factors, including riding style, speed, fuel type, and engine modifications. While some users have achieved impressive mileage, the small fuel tank size and varying conditions make it challenging to determine a precise figure for fuel capacity.

The reserve tank holds 2.6 gallons
The Kawasaki VN750 is a motorcycle with a small gas tank. Its total fuel capacity is 3.6 gallons, and the reserve tank holds 2.6 gallons.
The reserve tank is an important feature of the VN750. While some riders choose to rely on their fuel gauge to indicate when they need to stop for gas, others prefer to use the reserve tank as a guide. Once the main tank runs out of gas, the reserve tank allows riders to continue riding for an additional 20 miles or so at highway speeds. This can be helpful when travelling through areas without gas stations.
The reserve tank also serves another purpose. Some riders use the reserve setting occasionally to clean out any water deposits that may have accumulated in the tank. This is because water tends to sink to the bottom of the tank, and if the reserve is never used, it could result in a collection of water in the bottom of the tank.
While the reserve tank can be useful, it's important to note that the fuel pick-up line for the reserve is shorter. This means that when the bike is running on reserve, there is still some fuel left in the tank that cannot be accessed.
