boring out

[400EXrider#91]

i was wordering what would be the best bore for my 400EX...416,440,465...what do you think?

here she is on the old back yard table...its kinda small

[400EXrider#91]

oh yeah has anyone race cut their fenders themselfs? if so how and was it hard? can anyone help me out?

[MOUSE]

for the bore it depends on what type of riding you do mx or whatever.

and i cut my own fenders. started with a jigsaw then used a little sander to get them nice and smooth :cool:

i like my 416

invest in some boots, trust me from experience:devil


you do not look to big so i would say you should be happy with the 416, its a pretty big improvement over stock

[oynot400]

How much money do you have to spend? You could go with a 416 kit for a couple of hundred $$. That or you could spend over 3 grand on a TC 505.
What mods have you done and what do you want to do with it. If it is going to be a all out racer go with a 416 or 426 and a high compression piston. If you are just going to put around the trails and want some good low end torque then personally I like the 440.
Just remember a straight bore job will not get peak performance. A cam and some head work will greatly help out. Along with a pipe, filter, and a bigger carb.
There are many posts on this subject, go do a search and I am sure you will find what you are looking for. ;)

you look awfull small in that pitcure how old are you ?

[phatswinn]

red rider i was wondering the same thing, maybe u should be at least 15 before you start to bore it out, get some shocks from daddy first and a lenthened axle

[redrider ex]

Regardless if you are 15 or 25, you're not a "big" guy. So unless you are only looking to beat your friends in a drag race, I'd go with suspension. It will make you a better rider, and a much better jumper.

nothing can make you a better rider,you can only make urseld better

[Sparks425Ex]

You can't make your self a better ride just with mods but you can make yourself faster with mods. Suspension deff makes you faster on a track or anywhere. But you my not get any better.

Get Shocks first.

[wilkin250r]

Yeah, I didn't phrase that very well. It won't make you a better rider, but it WILL make it easier to handle and go faster on the track, which should allow you to PROGRESS faster in your riding ability?

[Andrew400ex]

yea thats about right..

[400EXrider#91]

ok i'm 14and a half and 5'6 150 pounds now that pic is me a year ago...so i have a 45' double and about 10 50' tables in the fields around my farm...i plan on starting to race soon at the local track(nonAMA) there is 250rs and raptors and stuff there so i need to steap the motor up a lil so i don't eat dust all the timeout a 10 riders i am usally around 3-6...thats just with a PC pipe and k-n
ok talk to you later...

-Corey-


P.S. i will get a new pic tonight;)

[BigThumper33]

Having a larger motor is nice but you can only go so fast over whoops, braking bumps, etc. Suspension will play a much bigger part in you winning races than your motor. I'm usually in the top 5 out of the gate at my races and I'm at the stock bore, heck I don't even have a new cam yet.

damn you ride a 400. o well i love my 300. im 14 also at 5'10" and pretty short around here considering my friends are 6 foot. i am smaller than you too. i weigh 127 pounds. nice 400. gotta love the yellow. i want to race also in longisland this kid told me stuff about it

[300exryder]

im sort of hoping i can get a new quad sometime soon, either a new honda with reverse if they ever make one or a raptor. Im 6'2" and 200lbs. The 300ex is still doing it for me tho. Its not like i race or anything, just a trail rider. Any one have a cheap raptor for sale?

[Andrew400ex]

im 15 and im 5'5 at about 110lbs. haha i been riding my 400 when i was 14 too and i was a lot smaller than. i got my 250x when i was like 5' and like barely 80lbs. haha its all in the skill

[400EXrider#91]
