red
Actually, it's red for 98 model years and later (anything manufactured after Dec. 31, 96). Note that most 98 models were manufactured in that latter part of '97, 97's in the latter part of '96 and so on.This applies to all two strokes and any four strokes that don't meet emissions requirements.
Your bike definately is a red candidate, but you can assure yourself by looking at the VIN#. If there is a C or a 3 in the eight digit, it's red. Many of us in California have the offending digits, but still get a green sticky (because it was applied for when new). The DMV probably doesn't have the manpower to check the eighth digit of every dirt bike registered.
