TSO Garage Note
An essential service kit for high-output two-stroke builds. Exhaust leaks at the spigot rob bottom-end power and create messy carbon buildup down the front of the cases. Keeping a fresh set of these high-temperature O-rings and high-tension springs ensures proper pipe positioning and an airtight seal under aggressive racing frequencies.
