got to keep you guys updated! haha, here is the update on my 400ex. i added an hmf ballance pro series slip on and a 450r carb with ZRPilot adapter. runs a 195 main, 52 pilot, a/f screw 5 turns out (needs a bigger main jet, but until then it runs mint, no more popping on decel). tell me what you guys think!

Thats a BAD ASS sounding 400ex!!!!!

God damn that thing thumps i love it!!!!

Id own that in a heart beat!!!

thanks man! yeah i love it! i thought it ran good before but after putting on the hmf pipe and 450r carb it really woke up! i got HUGE gains in bottom end and all it wants to do is lift the front wheels and spin the back tires! i have only owned it about a month now, i paid 1300 cash for it. since then i added the k&n air and oil filters, changed oil with honda racing oil 10w40, added the hmf pipe and the 450r carb.

niiice ex man, i swear them tires might be a little more bald then last time, lol, time for some fresh rubber

thanks bub! and yeah i got some front tires to put on but haven't had time to switch them over yet, and until i can afford new rubber all around i'm just going to switch hubs and run what was on the back of the blaster. that will work until more cash comes haha.
