What do you think would win in a drag race my friends 99 400ex with a 440 kit,stroker crank,ported and polished,electron carb,pro circuit t-4,and a k&n or my 04 yfz450 with a full curtis sparks pipe,k&n,proflow intake,and rejetted? Riders where both pretty good but i think i am a better rider and as far as weight were about even. He claims his ex will hand my yfz it's *** what do you guys think?

The kid claims he will get 76 mph out of it but i remeber back in the day when all the motor work was first done and the guy befor him that had it was getting 71 mph out of it.

i have seen alot of ex's with similiar mods at the dirt drag strip out run yfz's with those mods...consider this tho tha drag strip was ran on 200ft so that might make a lil diffrece.

well i could gear a stock 250ex to do 100 mph but that doesnt mean it is fast
