Compatibility issues due to drain holes
When it comes to the compatibility of Suzuki Mk1 and Mk2 fuel tanks, one of the key considerations is the number and placement of drain holes. The Mk2 fuel tank has two drain holes underneath, while the Mk1 tank has only one outlet. This discrepancy can pose a challenge when attempting to interchange the fuel tanks between the two models.
The difference in the number of drain holes can lead to potential issues with fluid drainage and venting. The Mk2 fuel tank, with its additional drain hole, may provide better ventilation and faster fluid drainage compared to the Mk1 tank. This could be a crucial factor for riders who frequently ride on rough terrain or perform stunts, as proper ventilation and drainage help prevent fuel spillage and ensure the fuel system's efficiency.
On the other hand, modifying the Mk1 fuel tank to add an additional drain hole should be approached with caution. While some riders suggest using a Y-connector to address the drain hole issue, it is important to note that modifying fuel tanks can be risky due to the flammable liquids they contain. Any modifications should be carefully evaluated and performed by experienced professionals to ensure safety and avoid potential hazards.
It is worth noting that, in some cases, riders have successfully interchanged fuel tanks between the Suzuki SV650 and SV1000 models, which are both considered second-generation bikes. However, even in these cases, minor modifications were sometimes necessary. For instance, when fitting an SV1000 tank onto an SV650, a small amount of metal needed to be cut from the bottom mount to ensure proper hinging. While this modification did not affect the fuel-holding capacity, it highlights the potential need for minor adjustments when swapping fuel tanks, even within the same generation of bikes.
In conclusion, while it may be tempting to interchange fuel tanks between the Suzuki Mk1 and Mk2 models, the compatibility issue due to drain holes should not be overlooked. Riders should carefully consider the potential risks and challenges associated with modifying fuel tanks. It is always advisable to consult with experienced mechanics or seek guidance from manufacturer guidelines before attempting any modifications to ensure the safety and integrity of the fuel system.

Y Connector as a solution
While it is not recommended to modify fuel tanks due to safety concerns, it may be possible to interchange a Suzuki Mk1 fuel tank with a Mk2 model with the use of a Y Connector. This solution specifically addresses the issue of the Mk2 model having two drain holes, while the Mk1 tank only has one outlet. By utilising a Y Connector, the single outlet of the Mk1 tank can be adapted to accommodate the dual drain holes of the Mk2, potentially allowing for a functional interchange.
It is important to note that this solution assumes that the fixings of the tanks are otherwise compatible. If there are discrepancies in the mounting attachments, it is unlikely that the tanks can be interchanged without significant modifications, which may compromise the integrity of the tank and its paintwork. Therefore, it is crucial to thoroughly inspect the tanks and their respective fixings before attempting any modifications.
The Y Connector solution is a relatively straightforward approach to addressing the drain hole discrepancy. By splitting the single outlet of the Mk1 tank into two channels, the Y Connector effectively mimics the configuration of the Mk2 tank. This allows for a secure and proper drainage system, ensuring that the fuel is directed through the appropriate pathways within the tank.
When considering the Y Connector solution, it is essential to source a connector that is specifically designed for fuel systems. This ensures that the connector can withstand the demands of the application, including the exposure to fuel and the associated pressure and temperature conditions. Additionally, the connector should be compatible with the materials of the fuel tank and other components to prevent leaks or corrosion.
Overall, while the Y Connector offers a potential solution to the interchangeability of Suzuki Mk1 and Mk2 fuel tanks, it is important to approach any modifications with caution. Safety should always be the top priority when dealing with fuel systems, and thorough research and consultation with experts in the field are highly recommended before proceeding with any alterations.
