I would get as much of your add ons as possible then rejet. This way you dont have to rejet for every part you replace. But dont drive around hard without rejetting. The more air you flow the more fuel your going to need. Without the rejet you could do some damage to your atv. Also you can step up to a hotter sparkplug

wats a hotter spark plug gonna do??

Put sugar in his gas tank. I think that going down a tooth will help you come out of the hole quicker. Then adding the slipon filter etc will give you more horsepower througout the powerband. Will it be enough to warrant a rev limiter remap im not sure

Send CK a pm. He drag races atvs

PM????????????

You might just want to take the spark arrestor out but you would have to add more fuel. You might lean out the mixture too much and burn up your valves

ha i dont want to be fixin things i want to improve lol..... ohh by the way i should mention the ex hasnt been rejetted since i put the white bros on

If ya want real gains do a stroke or bore upgrade and a cam. Those plus the intake slip on and dynokit will.really make your quad fly.

If you wanna play you gotta $$$$$

ya i just want to stop him from creepin past me in the cheapest way possible

I have a wb and its not restrictive at all. But any slipon will flow more air than stock

Sent from my SGH-T959V using Tapatalk

ya i have a white bros on right now

You should switch to a.free flowing exhaust (any slip on really) a free flowing intake or air filter

For stage two you need to open your airbox either by removing the lid or using an ehs kit

Then the dynojet kit will make hp. Without mods the jet kit wont do.much cept make your.wallet lighter

one tht blows out more air u mean than the white bros....... i was thinkin of buyin k&n air filter with an outerwear pre filter and then just cuttin the air box off and put in the jet kit

I have a dynojet stage 2, whitebros slipon, k&n filter and EHS airbox lid and i prolly freed about 6 max rear wheel horsepower

Remember a company makes hp claims using perfect parameters not on the trails

ya i see wat ya mean.....and im talkin drags so i need to find a good combination so he wont just loose me off the start and in the end i will pull on past him

With 20" tires in the rear a great combo is 14/38

With 22" tires 13/38

Dont enlarge the rear sprocket as you would lose ground clearance

Sent from my SGH-T959V using Tapatalk

i guess mine r 20" i think ......... like i said i want to be able to pull past him and keep him from creepin past me

If you go 16/38 you would have all the top.speed you need. In fact you wouldnt have a good bottom end at all.

Sent from my SGH-T959V using Tapatalk

would the dynojet kit help at all its suppose to add 15 to 25% horsepower..... i want to still have a pretty decent bottom end

What year u have?

2002:yes:

I rode arount RAC today with my 13/38 combo. It produces a lot of twisting power. I had to adjust the drive chain on the trail as it stretched. Too much power in fact it would break the rear tires loose on the trails. 22" rear tires coming soon to bring my top speed up. I can however crawl through the trails at walking speed without touching the clutch.

thts good im lookin for higher top speed with good torque combination

A 13t on the front of a 99-04 significantly reduces top speed.

Sent from my SGH-T959V using Tapatalk

i dont want tht to happen..... if i was to do a 16t in the front and keep a 38t in the back and then buy a dyno jet kit would tht raise top speed significantly and the jet kit would restore lots of torque??

i am changin my sprockets i want to add more torque but not lose very much top speed wat size should i use...... i would like to change the sprockets so i can beat my buddys 07 400ex with hmf slip on and rejetted..... we top out and then he slowly creeps past me:skeptic:..... wat size i need to stop this prob????

Good Morning . . Hope the new year is going well.

Mornin!!!....... my new year is goin great my ex is in pieces!!!

ight tht is wat i needed to no guys thanks alot...... tryin to decide wat sprocket sizes to put on my ex...........................

Heard the same thing later years dropped a front tooth

Sent from my SGH-T959V using Tapatalk

does anybody no for a fact this is tru??

hey is there a difference between the stock gearing on these models.... the 02 is 15t 38t...... r the others diff i hear the 07,08 is 14t 38t

okay, cool! i'm 5'9 without shoes by the way, lmao! so should i be good?

no prob man!!!! and yes ur hieght should be just fine i drove a 250 for my first bike also and i had no problems:yes:

I currently have a 2005 trx450r, which i'm trying to sell in order to buy a dirtbike! The only experience i have on a dirtbike is when i had my kx85 for a few months. I'm debating on whether i should get a crf150r or crf250r to start with. I know the 250 is big, and has a bunch of compression at a ratio of 13.2:1. But what do you guys think?

take the 250 u will just have to start out easy but u will get used to it...... i learned on a 250 as well...... even though i realy dont ride them anymore..... take the 250:yes:

I haven't found an atv that will touch my Z440 yet. Ltr450, trx 450s.. stock and modded. I recentyly did some work for a buddy on his 05 R6. Dragged 1/8 mile against my 440, beat him and he was so pissed he accused me of messin with his bike just so I could beat him haha

awsome!!!! it looks like a sweet bike:yes:

and a happy new year!!!!!!!!!!

Good Morning! It's X-Mas Eve!!!!

good mornin hope u have a great christmas!!!!!!!!!!!

merry christmas to all!!!!!!!!!!!!!!!!!!!

what is your preference on the location of gear selector and why?

i like left hand selectors because you don't have to take your hand off the throttle.

same here i like them on the left side!!!!!

I grew up on a yammy semi manual shifter. So when im not paying attention I upshift or downshift without the clutch on my 400EX. The owners manual says major damage will result but I havent noticed it yet

ya its not good for them i have only not used the clutch twice and tht was because i was holdin on to something...... if u do it alot it will cause problems!!!!!!
