Did you change anything since the last time it was running well? If not it may just be a dirty carb. Also check to make sure the tank breather is working correctly.

 

i took off the hose breather compleatly it start right away but once i get it moving and try to get on the gas it will pop/bog and them start to accelerate ohh and i tried to do some donuts in it today and it felt like a dog i could not get it to rev over 3k and it was poping like crazy.

unrelated question

today when i was riding the ds my arms were killing me is there anyway to soften steering and the thumb throttle it makes my thumbs and arms real sore

 

i also installed a spring out of a 03 carb so it is shorter i dont know if that makes a diffrence but i thought id throw that info in there too thanks again.

Sounds like you did not get the bladder seated properly when you changed the spring.
Take the top of the carb off and check the bladder for tears.
If OK,
spray bladder with a light coat of wd-40,
install top and move top slightly side to side to help the bladder edges to fall into groove.
tighten top down.

If this does not help, let us know how it runs this time and we will help somemore.

im going to try that today once i get back from work will let you know how it turns out thanks again.

yea omr has this one i am almost certain becuase mine was running really weird one day and would accelerate instead of almost stall and I took the diaphram apart like omr is saying and it was slipping off mine wasn't torn and the spring needed to be adjusted and I sprayed it the diaphram with wd40 and then after that I also took out all of my jets and sprayed them with carb cleaner and she ran great after that. Just update us on how its running thanks.

i didnt have time to check it out today but i will tommorow if the bladder is torn how much is that peice to replace

 

update

i have taken out the bladder it looks fine but one of the screws that holds the top part of the carb was stripped and wouldnt close it all the way down so i think it was sucking air thru there got it fixed im going to test out the bike this weekend beacuse i cant drive the quad around here my neighbors are a little **** about that kind of thing last time they called the police beacuse i had the bike on in the back yard.
