    250x/400ex

    I agree, post up some pics of the front end. Also pos some pics of your 400ex fenders and how you mounted.Theres alot of people on here looking to do the same swap.And wich way are tires pointing? top to bottom, or toe to heel?If you have problems posting pics, I can help.

    i doubt the shock would have any effect on the camber/caster of the wheels.

    but as others stated: its hard to determine your problem without a pic.
    If you can't modify it why have it???

    the tires sit caved in, i can adjust it so that either the top is leaning in towards the frame and the bottom out or the other way around... my tires wont sit straight. idk if its the 400ex a arms that did that or i messed something up i will post some pics (is there a special way to get them on here how do i add them)? i want to fix the tire problem because its going to be only riding on the inner part of my tire and wear them off way to fast, but it still handles like my 400ex but turns like a tank because i got a 5 inch wider rear end also... i will post pics if i can figure it out and you guys let me know... thanks in advance

    my fronts plastics are not on yet but i made my own mounts, will get pics of it now and when finished, but best thing to do is to have 400ex mounts which works best... i made my own mounts easy because i have a 400ex and just made it buy measuring and looking at my 400, nothing to it

    a arms

    Hey, I sent you a PM. Also I have a 2001 400ex rear fender mounted up on my 250x,but I still have 250x front fenders. This is why I was asking about how you mounted your fenders up, and how do they look? Please keep me posted.
