hi all, just a question about my atv i've a bigbear professionnal YFM400FW and when i search on web pics of him i found that the Kodiac 400 is more similar then mine...for example the headlights are near in mine like the Kodiac. Maybe they're differents versions to europe/japan/US market? If i take service shop for bigbear 400 i can see a chapter for radiator/coolant but my model is air cooler with manual 3 positions shifts : high -low speed and rear... If someone have some info for my Atv? when i try to put my 17 number to know the year : it says that it maybe a japan model..... I had recently to change my carb intake manifold and i put a kodiac one....It's very difficult for me when i purchase something for this Atv to know what parts gone on mine.....
