When changing valve springs for performance upgrades, or simply replacing a leaking valve seal, it is necessary for the technician to completely remove the cylinder head from the engine, which adds unnecessary time and expense.
This "revolutionary and creative new tool" developed by Camarillo, California based JIMS eliminates this step completely.
"Our patent pending 'on bike' valve spring compressor kit for M-8 engines works with the cylinder head installed on the motor. Simply remove the rocker box covers and rocker arms and install this unique compressor on the rocker arm shaft. Once the cylinder is filled with compressed air, the technician can easily rotate the tool and compress the top collar of the valve spring, exposing the keepers to remove the top collar, valve spring and seal.
"This tool dramatically saves time for any technician working on M-8 performance upgrades or service work."
