my friend gave me a his extra carb off his 2000 kawi kx250. he didnt know the size of it but i did little research and i think its a 38, 39mm. i was wondering if this monstrous carb will mount up on my stock intake. of course IF it does fit i'll have to have some big mods.. stroker, 240, ported etc.. but its free so it least i know i have a good carb to match when i get all the engine mods done..
