Ok, ran the bike   stock, lil modded, now got evan more mods to  it. Last time i ran it it was 63.0 mph and 10.3 sec  in the 1/8 mile. I no its still very slow  but its work in progress. i just re jetted the carb took off slip on system and put full system and mess with the gears  lets see how she runs on sat night at countyline. 

63? My 03 was gps'd in the mid 70's with a yoshi pipe, and a +1000 rev box.

He said in an 1/8 mile. You were probably wide open a lot longer than an 1/8th mile.

Just to give you an idea of what a 450 with a pipe can do, I ran my YFZ on the 1/8th in Immokolee and got a 9.3 at 72.

But you can have that with some extensive engine mods... but your bike wont be the same for off road anymore.

Also if you get the launch down you can pick up some time.

It would also help to take a dump just prior to your race. Every little bit of weight loss helps. ;D

that is true i did   63 with stock pipe  i got full system now so i will let you all no how it runs after that.  i am getting cams, valves, springs, and port and polish the head   for the next step.   

If you're going to pull the head, you might as well put in a higher compression piston. You are 3/4 of the way there already. If you don't want to run race gas stay at 12:1.

i do wanna run race gas   i was thinkin pull the head now and leaving rest alone   for a lil because i really wanna run the 470 stroker kit with 15:1 comp piston and nos on it when i am finshed i gotta do more to the sus  before i can evan start to do that. my freind morks for machine shop so he is gonna do my porting and valves for me

this that 400 you told me way back that was going to run my banshee? might want to check again on that, spinning off the line with on dirt tires i was running low 9's an thats with pipes an a cool head with stock domes and an open air box... let me know if you need some company out there some time

i am going sat  night  you should def   come  and no  this is not same bike its a dif one. i have a feelin that i will be in low to mid 9 now just a feeling

i doubt i'll make it this week, need to pull it out, last time i rode it i think it had alot of clutch slipping, need to get it out soon an ride it

you still got a few   days tog et her ready 

if i wasnt in school all day it would be a possibility, maybe if i get working on it saturday morning i can have it good to go

If you are running stock suspension take all the rebound and all the preload off of the rear shock might make it a little softer and suck up some of that energy when you are launching it. PRACTICE your starts and you will see improvement for sure.

This is what you need, Z450 running on Alky

thats a very pretty bike i like it alot. how do you take all the rebound and preloud out of the rear?

Curious, but what mods were done realtive to the fuel injection electronics to handle alcohol?

It's a Z400 with a big bore kit. I would guess it still has a carb.

For some reason I thought it was a new 450.

No EFI, I believe it has a 44mm Lectron Carb.

 Wow, thats a long list of mods.
 The only mod that I had to do to run alcohol was to buy a Rhino :T. that bed will hold a large cooler with plenty of alcohol for a long day of idiot watching.

One other bit to help in the suspension dept. Take a tie down strap or ratchet strap and use it to compress your front suspension all the way down.

went out sat night i was the only  atv out there lol.   i was runnin  consetint   65/68mph   in 1/8th mile now. rec time  .780/.890 (so i need to work on that) and 9.992/10.121 time.  I  think my gears   are still wronge but i am gonna tune it up   and see what else i can do. i no its still slow but its getting up to speed now.

man, whats going on that you picked up so little from changin to a full exhaust system? i would think you would pick up more? what gear are you in when you go through the traps at the big end?

4th and its not wound out   i need  dif gears

oh man, five speed or six? you should be going through in top gear, atleast thats the way i have always done it, i usually hit 6th right at the stripe an just try to run out 5th

its 5 speed i got stock rear  but i went one down  in the front  it gave me more of the line but seems like my top end is gone.

Yeah, a bottem end sprocket will take off alot of top end. I currently run a 13 on my mx, but I think I'm gonna go back to the 14 because my 13 revs out the quad too quick, I find myself in 5th gear, where as with a 14 I am in 3rd gear producing more power.

yea i like the 13th when i am trail/rec riding ats alot of fun   just seems i loose alot of top end
