    Carb rebuild

    carbs are not funny. what's funny is the totally inaccurate info given by those that shouldnt be giving any info! the pump bowl will not change anything in the jetting unless you are actually twisting the throttle fast enough to engage the pump to squirt into the carb throat. mid throttle is controlled by the needle size, taper and its clip position. usually you are 1 clip too rich if it bogs here. move the clip down 1 notch (ie that would be towards the top). the funny part is...thats shown in a picture in the back of your manual.
  2. use any cam between 01 and 13 that you want they all fit
  3. its not like you could simply pull the clutch cover, remove the pressure plate and actually SEE if the ball is there next to the shaft like it should be. no just keep guessing.

    the all ***new*** YZ250FX

    i stupidly commented on the altitude. i hadnt see the fische on the sensors.

    still no compression in yz250f

    the rings are not seated. take the spark plug out. put 3-5 drops of oil down the hole onto the piston crown then 1 squirt of wd40. and 1 squirt of engine start. plug back in quick. after about 5 cranks it should really stiffen up as that little bit of oil will seal the rings to the cylinder wall. now you can accomplish the same thing with about 50-80 kicks of the lever because that takes the sharpness away from the ring edge but idealy that needs to be done by the running motor not kick start lever.

    Aluminum conversion short list.

    well considering that the 2006 is an aluminum frame, yes on the 03-05 not much direct swap my good buddy texlabo (find his post) converted an 05steel to an 06alum. in the end it took so much of an existing 06 that it became an exercise in wrenching. bazooka yes i think it was the infamous psellers from bangadadangdang (banjo sound) alabama that produced the worlds most expensive roach bike.

    Aluminum conversion short list.

    simple answer -> you need a rolling chassis without a motor, but with EVERYTHING else. not simple answer...the list is longer than your leg.
