Kawasaki H2 SX Problems

The Kawasaki H2 SX, renowned for its power and performance, has come under scrutiny for a potential problem relating to the supercharger impeller. While the issue may not be widespread, understanding its intricacies is essential for owners and potential buyers.

Identifying the Problem

The main concern revolves around three bolts located inside the air filter housing. If these bolts are not secured with threadlock, they may back out and subsequently pass through the supercharger impeller. Such an occurrence could lead to severe engine damage.

Comparing Different Models

The Kawasaki H2 SX is different from the H2R and the Z H2 models:

• The Z H2 and H2 SX use entirely distinct superchargers compared to the H2. This distinction implies that if the intake system varies, the mentioned problem might not affect these models.
• Parts diagrams reveal that the H2R model might not have the same issue since it doesn’t have the air filter housing directly bolted to the supercharger. Instead, the intake pipe from the fairing fits directly onto the blower.

Addressing the Issue

Several points were noted regarding this potential issue:

1. The problem primarily appears to have been reported in the early models, with the video example being a 2016 model.
2. Kawasaki seems to have addressed the issue in newer models.
3. It is crucial for Kawasaki to proactively inform owners of affected models about this concern.
4. There are speculations on whether missed service sessions or a recall might be the reason for the problem in some bikes.
5. While the H2 SX might be an unconventional choice for track day enthusiasts, many still favor it for its performance.

Conclusion

While the highlighted issue may not be prevalent across all Kawasaki H2 SX models, it’s crucial for owners to be informed and vigilant. Regular servicing, staying updated on recalls, and understanding the bike’s mechanics can go a long way in preventing potential problems and ensuring the longevity of the motorcycle.
