My 10letter is an xSerial number on front of quad behind front bumper, generally stamped into a frame crossbar. The tenth letter/number from left to right will give you the year. There is a chart posted by Helmut on the forum that will help you cross-referance. Type in model year chart in the advance search field.
FOUND IT! I’ve had my fourlwheeler since ‘01 and I found out it’s 2years newer than I thought.. yesssss...(in my Napoleon Dynamite voice)So I can’t see the chart you posted and all i know it the tenth number/letter is a “W” which ales it a letter.. this is driving me nuts!
