I have a 00 warrior and i ti si braking a lot so i was thinking of getting a ex insted. i am 13 and love my warrior powe wise. would an ex be the right bike 4 me whut are the differencos between it and my warrior?
thanx!

 

The ex is more of a sport bike. The warrior is nice but it is heavy and has little ground clearance. The 400ex will have more power and handle much better. Good luck

 

400ex handles way better and has about 8-10 more hp, its also a much sportier machine

 

I live in Reno Elevation is about 45oo feet above sea level run a white brother pipe on back with K&N filter do I need to jet up or down it seems to run fine now but can't really tell if I need to do anything,,,as well I never got a head pipe with this white brothers do I need one will it help any, It cost about extra $200 would it be worth getting any more power??? Also my friend bought a 03 predator do I have any chance with keeping up with Him or do I need to go find a corner to crawl in??? Has anyone drag raced one with their 400ex??? results??? we will ride trails and sand together...

 

Thread Hi-Jacker!!!
Read the plug, that will tell you what to do with jetting.

 

don't get the head pipe until you do motor mods (if you're planning on doing them.) I put one on mine and it made no difference. The slip on with K&N did make a nice difference. Now that the motor is modded the head pipe is probably doing some good

 

Friend I didn't find that info thx, jim

 

ya i had a warrior it was a 99 and i had nothing but problems with it i had it for about 6 months and never drove it in the winter i bought a new 03 400 ex and love it the front end lifts up so much easier go for the 400ex big difference

 

I remember driving your Warrior. I love your 400ex so much more even though it doesn't have reverse. The differences from the Warrior and the 400ex that I noticed:

The 400ex is more confortable
The Warrior feels harder to shift through the gears (it's easy but the 400ex is so much easier)
The 400ex feels so much more powerful

 

I also live in Reno. I have found that the guys at BVH motorsports are very helpful when it comes to these questions. Your best bet at this elevation is to up your main jet to a 152 with a slip on. fast440 is right. You will basically be waisting your money with a head pipe and no engine mods. You may even lose power. And as far as racing the Predator "No chance of a win there". You would have to seriously modify your EX to even come close in a drag race.
