if i get a lex mxe slip on pipe for 04 400ex what jets should i get for it?
I am also getting new rubber for it whats the best ITP Holeshots or Maxxis??

 

I'm new about this stuff but eeeh, what kind of riding do you do mostly?
and is that you on your quad?

 

not sure about the jets but if your looking at holeshots they have another CST tire like a holeshot. Look really good and about $30 cheaper. I would get the CST ambush on rear and ITP holeshots on the front

 

ya its me i just want a machine that sounds a little better, and has better acceleration and hooks up nice. Little more power too cuz my dad has a kfx 700 and he always beats...
i ride in a mostly gravel but there is some water/mud holes and a little sand

 

dont think a piped 400ex will out run a 700xx.

 

ya i know but just want a little more power to stay by it

 

Just a slip on? Try a 150 main with the fuel adjustment screw 3 turns out. Then do a plug chop and adjust if needed.

 

okay , i have to post this one, heres a chart of power increase if you'd ever like to switch to HMF on your 400ex.

 

thanx a lot that really helps
