Ok, This is my first ever ATV. a 1997 warrior. It has a DG pipe, KN air filter and was properly jetted. The boot from my air box to my carb ripped to instead of buying and waiting for that part to be ordered I went ahead and purchased one or thise foam air cleaners that attach directally to the carb and deleated the air box all together since I am not into mud bogs or deep water. The Warrior runs perfectally untill I hit 2/3rds throttle in any gear then it starts to caugh and sputter like crazy. What is the problem and how can it be solved? Thankis in advance

 

well my friend has a 98 warrior as it sputtered and he changed the spark plug to a ngk racing spark plug and it stop sputtering and if that doesnt help u might want to re-jet it......did u re-jet it when u got a new pipe?

 

When I bought it a month ago it ran perfect. when I changed air filters it started sputtering. I told the dealer that i bought the foam air filter from that I used to have a K&N. He said that the KN and the new foam filter flow about the same and that I should not have to re-jet.

 

ahhhh. i didnt read ur thing all the way sry.....but on my old quad i didnt have a air box but if ur air cleaner get wet and ur carb sucks air it wont run right u need a air box or it might be sucking to much air thats y u need a air box...........even on my dirtbike right now it doesnt have a air box and i went through a mudd puddle and everytime u got it up to speed it would spit and studder really bad i couldnt run it right

 

its really doesnt matter if u take it threw deep mudd or anything as long as water hits it and get it wet pretty good it wont run right

 

Your dealer is full of shiz!! K&N's lean everything WAY out when I first out mine on and took off the lid the plug was completely white. Now that youve gone from K&N to foam u are probably running rich.

 

Well, I got one vote for to rich, one vote for to lean(to much air) is there any way to remedy the problem without rejetting. I don't need the air box because the conical air filter fits directally onto the carb. any other info/suggestions would be graetly apprectaited and thanks to the guys who replied.

 

start with the plug thay are inexpencif and esy to replace, also thay breal or grt dirty esy.

 

That was the first thing I thought of was the plug. I replaced it and it did no good.

 

i would just buy a air box to keep the air cleaner clean
