i traded an old 95 jimmy 4x4 for an 01 400ex a couple years ago since iv gotten it iv replaced chain sprockets,bearing carrier ,dmc slipon ,seat, tires and all kinds of misc. stuff. well i tried replacing the swing arm bearings so for a month now iv been spraying with pb blaster and trying to pound out with a 5 pound sledge with no success so after cutting out iv decided to paint another frame i had and swap everything over . my uncle has some burnt orange paint leftover from a jeep he just painted so im going 09 450r theme with burnt orange frame and 05 white carbon fiber plastics and everything else black. im gona paint the frame to save $ to put into the motor plus im sand blasting everything and its auto paint with hardener and il do couple extra coats of clear.as for the motor i plan on doing a 416 11.1,hd studs and camchain and stage 2 cam nothin special but i should see a serious difference from the worn out stock setup. im gona try to down load pics of progress im sure il be asking lots of questions but i think it will be a good look whatch yall think?

Sounds cool, give us some updates as you go!

You're not the first one to decide to just rebuild the while thing after struggling with those pesky pivot bearings..

@ pbc400ex

I (as well as a couple of others) have added 450r swingers, just make sure you buy the 400ex pivot bearings, and reasearch the bearing carrier issue, its said to be off 1/8" in width compared to the 400ex one.. I used all 450r parts (swinger, carrier, brakes) so I dont know anything about that problem.. but It is easy enough to mod from what I've heard..

Good Luck! (Heres's mine, I rockguarded it black, seems to be holding up good)
