My 2000's petcock screen was torn.?? There was no way I could figure to replace just the screen.? Also my petcock wasn't shutting off the flow of fuel when there was no vacuum on it.? I replaced the whole petcock with Yamaha part #5LP245000100.? The Yamaha petcock is a basic on / off type (with no vacuum connection) but looks essentially the same as the original and fits the tank perfectly.? The reasoning was to simplify the system and when combined with the removal of the KCAS system I was able to get rid of all vacuum connections to the carbs. ? The Yamaha petcock was also a good bit less expensive than the original Kawi one. ?
