i am going to run my 99 400ex at the track tonight in the 1/4 mile. what do you guys think it will do? i have a white bros. e seriers slip on, filter, and jetting. im thinking 16's, any ideas?

 

well youre 60ft time will be amazing however you top out at like 55 if that , so once you reach that its slow going I am thinkin prob 20's.... plus on the street traction is too great and you wont be able to launch it very well , first will be useless.... good luck let us know your times

 

my kfx ran a 14 so youre ex will def be in the 18 or 20s

 

lmao atv steve if your kfx was stock their is no way its doin under 17 seconds..

 

well i ran, and i ran a 17.9 @66mph kinda disapointing, but owell

 

You have 400cc engine, four wheels on the ground, quad that is close to 500lbs + rider, what did you expect. Although probably fun to do ATVs are not designed to run record times on a 1/4 mile track, so I wouldnt be to dissapointed.

 

my 450r run low 13's at 95 mph. i am going to try and hit 100 b4 i am done with it..

if you strap the front and rear of your quad down you will launch alot harder.. or just get the crj lowering links....

also that sounds about right with a 400 what gears were you running. if you were running stock gears and you want to race on asphalt 1/4 mile anyway...

go up one in the front....

 

Thats not bad for a 1900s aircooled 400ex. some guys would come on here and say they did 100mph at 13.0

 

yeah i have a 14 tooth, but i think it wouldnt do me much good (or better) because i figure it would top out way too early and i would lose top end (even though i would gain accel.) but i think i will try it some other time just for kicks. but yeah no 100 mph at 13 secs here, although i did not hit my goal of 16 secs, i had alot of fun.
