I was helping my buddy with his 400ex and we were changing out his main jet and theres a jam nut on

the main jet i guess to help put the main jet further down into the bowl, anyways i wonder if i could go

buy a low profile jam nut and go by the same principal on my raptor. It works on the 400ex and the basic

format is the same just put your jam nut on the main jet and then run up in your carb and bam! the main

jets is deeper in the bowl maybe fixing the problem with the cutting out in extreme angles.

 

That would make the problem worse, not better. The problem with it cutting out on an angle is the fuel level is too high, what your doing would be the same as raising the level.

 

But i think that i can tell that i can wheelie and it will go good cut out then go good i think if the main jet was a little further down it would be more fuel into the bowl.

 

Isn't there a saying about exp. being the best teacher. Give it a try.

Whats happening when you wheelie is the main is sucking to much fuel, not too little. Lowerring the main more into the fuel is just going to make the problem worse...IMO, but it never hurts to try.

 

how can it suck more fuel from being in an almost upright position

 

Take a glass, fill it 3/4 full of water, stick your finger in the middle of the hole just above the water level, and turn it on its side with you hand coverring up the rest of the hole.

How wet does your finger get?
I know thats not a real accurate test, but....LOL[img]i/expressions/face-icon-small-confused.gif[/img]

 

yea but i figured a bowl is not as deep as a glass nor is a finger as big as a main jet

but when it wheelie it gets gas then it quits getting gas then it gets gas again i thought maybe its because the bowl is full but its not just quite at the level of the main jet

so basicallly the bowl is full at the angle but its not at a approperate level to have a constan flow of gas and when it wheelies it starves for fuel thats why its cutting out

Im not saying your a dumb or saying i know more than you do ,its just i really am curious about it. Why does the 400ex have one it has to be good for somthing then again it is a honda.
