just got my 03 Z400 dyno tuned 46 horses at the rear wheels am working on getting some picks up and the dyno sheet can't wait to whoop up on some yfz first race is in 3 weeks will keep you guys updated

 

sounds great!!!!! what kind of gas do you run? do you have cams?

 

i run 100 octane allso known as cam 2 i have the hot cams and full head work port pollishing and flow tested and k&n no air box lid

 

i run vp's c-12 , i 'm running 13 .5:1 on a std. bore and stage 2 hot cams. do you like the 440? i was looking at the 435 athena then a got a shee so i just went with high comp and cams. will it eat some 450's??

 

you will most likely be real close and probally beat them till about 4th gear then the 450 will probally pull you they just have so much top end the 440 kit is good i just have had alot of carb issues with to lean to rich but now its tuned in

 

i was actually talking about yours,but thanks for the info. i raced a 450r with cams the otherday,he's about 50lbs heavier and had stock tires on(we were on sand). he was still coming out of the hole good. i went 1 tooth down on front sprocket, i took a big whole shot on him and was beating pretty good. we went about 200 + ft and he'd catch me at the end.i was pretty inpressed!!
i have a procom cdi thats adjustible but i have it on stock rpms.my buddy put my bike together and said i should run it on stock rpms till i get my kibble white valve springs in. i really miss that extra 1000 rpms. it doesnt feel like it pulls as hard on top. i thought about going back to stock sprocket.i was trying to get it ready and test it out before the clash of the titans in lousiana.after i get back im getting my springs in and a valve job done.
i also put a durablue lowering kit(front), man that really helpes me come out of the hole. i can sit about half way on the set and take off with out the front coming up!!
