I'm not sure of the exact details.....but owners of '97 and newer bikes that had been issued Red OHV stickers in the past are now recieving "Green Stickers". My understanding is because of the confusion at DMV many bikes were wrongly issued "Green Stickers"..(kind of the luck of the draw on what you got). The sytem of who got what sticker was so thrashed they're starting over for '03. From what I heard '02 and earlier bikes are now considered "Green Sticker" bikes.
I guess it's time for me to put the '96 CR 250 up for sale.
