i have a new 2002 400 ex bone stock and lately it has been having troubles starting.Even when its warm it has trouble to start again. I have to constantly pump the gas 5 or 6 times before it wants to start up. Has anyone had this problem or know why this is happening?

i tihnk ur problem could be caused by ur choke, make sure nothins wacky about it..... or else it could be ur idle, if ur idle is too low, it wont start up too easy, try turning it up some and if that dont work try the choke

Up your pilot jet to a 40 or 42 and don't use the choke when starting it..
