Just picked up an 04 400ex.

Just got ride of my dirtbike and back to atvs. I was wanting to get a 450r but got a good deal on a 400ex. For mods it has open air box, stage 2 hotcams and different sprockets(not sure on size). Anyways it really hauls *** for a 400. It feels pretty close in speed to a stock raptor 660 i used to own. Anyways I just ordered a lexx slip on pipe. It was cheap and the stock muffler is pretty beat up. So i was wondering if anybody has good info on jetting for this set up. It runs great for the way its set up now, im just assuming i will need to change the jetting for the new pipe. Thanks

Start with a 155 main, 42 pilot, needle in the middle and 2.5 turns on the f/a.

Just good timing haha. I was checking the forums one last time before going to bed. But yeah, that should get you pretty close for the mods you listed.

Oh, and welcome to the site.
