About the Honda SL90
Small sealing parts can address different leak points on an SL90 restoration.
A small SL90 sealing repair can involve the tank cap, petcock or exhaust joint. Identify the joint before ordering: cap rubber seals the filler opening, a petcock controls fuel leaving the tank, and an exhaust gasket seals its specified pipe or port connection. Check any substituted tank, tap or exhaust separately.
Check the component behind the familiar model name
An older SL90 may have a replacement tank or exhaust. Compare the tap mounting and outlet direction with that tank, the cap rubber with its groove and the exhaust gasket with its installed location. The motorcycle’s identification starts the search; the assembly details confirm it.
Know your SL90 before choosing partsSL90 repair checkpoints
Fuel tap and cap rubber
The linked fuel petcock is a replacement tap. The cap-rubber listing supplies a separate sealing part for the cap, not a complete cap or tap repair kit. Match each at its own location.
Exhaust sealing is a separate job
Compare the gasket diameter, profile and joint location with the exhaust fitted to the SL90. A fuel-system fitment match provides no information about an altered exhaust.
