watsup ppl i just joined this forum i got a real problem with my 400 -lookin 4 some help/advice- i just changed the oil and oil filter and it ran perfectly right after, but after a short easy ride i let her idle for a few minites n she just cutt-off. since then i cant get her 2 start. can any1 help me??

 

What kind of oil did you use and how much? Did you change the plug? Did you check all your electrical connections and fuses? This may be irrelevent but what is your current jetting? Are you using the choke? Did you make sure your kill switch is completly in the on postions are you using a tether switch? How much gas do you have once it gets too low it will kill out and not fire back up. I know its dumb but ive over looke stupid crap like that before. Post up on this site too you will get a lot more feed back in the 400ex section www.exriders.com im a member over there too.

 

did you over fill?

 

Did you put the oil filter in backwards, it can only flow one way.
