426 problems!!

[biggun132]

i just had my 426 and hotcam stage 2 installed. done my 4 break in warm ups and went out for a ride. before the build i was running a 170 dynojet main. i have the powerbomb header with a fmf titanium 4 pipe, k&n with open lid and a rev box. it was running great. so i put a 180 keihn main in and was lean real lean. im already up to a 200 and it still is pretty lean and is getting hot real quick!! what could the problem be?? thanks

Are you sure its not sucking some air somewhere? That would deffinately cause a lean condition
