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

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??

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

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

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

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

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

which is the reason for the rejet

After all my mods I did, I also used a NGK D9 plug. Its tan in color so I must be doing something right :)

Did you learn that the tanish color on a plug is good from your Hanna Montana fan club? "you get the best of both worlds, lean or rich, no right in between"

      So.. it a weird one.. The quad surges as you go down the road. By the looks of my tracks, it's one wheel only. High range, low range, 2 wd , 4 wd.. It just doesn't matter.. 
      You can see in the pictures the marks it leaves. That was in a straight line, with hardly any acceleration. 
      Any ideas?

      I've been using Valvolene 10w 40 ATV oil but, it's like $8.00 a quart. Is that about the going rate? Or is there cheaper alternatives that would be suitable? Thanks

      Ok guys Ive got a few more for ya.
      TIRES:
      Ive thought about getting new rubber for the wheeler it has some half worn down 25" Kenda executioners on it and Id like to get something that maybe rides a little better and does as good or better in the mud if thats an option. Any tire model suggestions? Also I would like to go to a 27" or mayb e even a 28" are there any disadvantages to doing this would I have to change anything on the wheeler to make up for the larger tires? Ive had a couple people tell me that they would be hard on the clutch.
      WHEELS:
      Ive seen some really nice looking aluminums but not sure they are tough enough to handle trail riding...Are they??? If so what would you reccommend, id like a little off set to give it a slightly wider stance and better stability but a buddy has a set of ITP wheels and the rear is offset a lot compared to the frnt and it looks great but hes constantly getting the back wheels hung up on trails
      SNORKEL:
      I see that the airbox on the brute is where a normal wheelers gas cap would be, so that being said am I good to go with water as long as it doesnt go over that point os is it not sealed up to the box? Also how about the belt and it staying dry, do I need to do anything to ensure that it doesnt get soaked and leave me stranded.
      Oh by the way I love this thing the more I ride it the more Im glad I went with the powerhouse, Ive run with a couple polaris 500s 700s a grizzly 660, and 700 and a couple rincon 680s that were built and they cant touch my stock 750, although she likes her gas thats for sure i got about 50miles and Im needing a refill
