August 3, 20188 yr Any info greatfully appreciated, just part rebuilding my first bike (fantic 303)to begin in the world of trials . The headset bearings are rough . Any suggestions on bearing size ? I read in another post the 240 uses 25x47x15. I dont suppose that would be the same on the 303? Also how tight do you tighten the spanner nut when refitting everything
