CJR HD Valve Spring Set - CRF110
Honda CRF110F upgraded valve springs for OEM cylinder head. When running OEM or aftermarket camshafts, we find the weak OEM valve springs hit a limit at 10,300rpm depending on camshaft option. These springs are a great upgrade for even a stock camshaft and even better upgrade when paired with an aftermarket camshaft.
Tested up to 11,200 rpm on stock head and valve setups.
