Well I put up a valiant effort to put the 400ex a arms on the 250ex. But I did fail. I just couldn't get the travel the way I liked it. So in other word anybody want to buy some 400ex parts?
I have a ported and polished head, 252x1 can, HD valve springs, wiseco 10.25:1 0.20" piston setup.
Just a little freshening up.
If anyone out there has an extra intake valve let me know.
