Essential wear part to maintain the sealing of Mikuni HSR and TMR carburetors in 42 mm and 45 mm sizes. This O-ring replaces worn or cracked original seals and helps prevent fuel leaks, unwanted air intake, and idle malfunctions that can affect engine response.

• Compatibility: for MIKUNI HSR42/HSR45 and TMR42/TMR45 carburetors.
• Usage: maintenance part for replacement during disassembly, inspection, and overhaul of the carburetor.
• Signs of wear: presence of fuel traces, fuel odor, unstable idle, or deteriorating settings after a restart.
• Installation advice: check the condition of the seats and surfaces before installation and lightly lubricate the O-ring with a suitable lubricant to facilitate fitting and avoid pinching.

Ideal for riders who maintain their own machine or for workshops looking for a reference replacement part. Keep the carburation clean and reliable by replacing the seals at the first signs of wear.
