Ill Try cleanin my carb but wouldnt burn through cause i burnt a tank allready

CHECK OUT THE AIR BOX AND AIR DUCT GOIN TO THE CARB. IT HOLDS WATER BAD, MY KFX WOULDNT RUN RIGHT FOR 3 WEEKS UNTIL I CLEANED IT OUT AFTER I SUCKED IN SOME WATER.

haha.... a z400 rippin past 450's....

I wouldn't laugh to hard my friends has a z400 that smokes most anything he races granted its far from stock but it still can be done

i wasn't saying it cant be done.... i just have a really bad attitude against the z400 ever since i had mine. thing was a fricking piece of poop

Operator Error maybe....
