I can get them for a decent price I think
The C14 is 80.04 for 12 or 6.67 each plus a bit for shipping.
The part # is 51358 and it fits a TON of other bikes
The Gen 1 is 3.91 each with both o rings
The part # is 24941 and fist most older Kawi's with the internal filter.
My SV650 is 63.48 for 12 or 5.29 each and fits most Suzuki's
