Is there a carburetor kit for a 1999 klf 300 4x4 ATV?

I don't think so, because the Klf 300 4x4 was not a very popular model. Try searching for Carboretor kits on the Klf 300 not the 4x4, because it was more popular. But im not sure if it has the same tuning as the 4x4. Good Luck.

PS: For a I thought of getting a klf 300 4x4 but then i settled for a brute force 300 4x4 ( kvf300 ) instead. :)
