  1. I'm putting the cam back together on my YZ426, and went to time the valves, and noticed there are 3 marks on the flywheel in that timing check hole. My flywheel is stamped like this: |-| | There's no tc or anything under either of the three lines, is the line seperate from the two with the dash the correct line to time your valves?
  2. Hey, I've got a YZ426 with a lifter bucket that's scratched on top, I took it out and dropped it, and on the top it scratched, I was wondering if I could sand this smooth or do I need a new lifter? thanks

    YZ426, cam wear in cylinder head

    valvae clearance is out of spec by .03 on all intake valves, on exhaust clearance is in spec. It is the stock cam. The wear on the cylinder head by the cam is preventing the removal of 2 of the lifter buckets, so unless I get these burrs out with the lifters in place, I can't reshim to get back into spec. The wear is on both edges of the middle resting groove for the camshaft, which almost leads me to believe the oil hole may have been or may still be clogged. Can I blow this hole out with compressed air to clear any possible blockage? Is there another way to clear a clogged oil feed hole? I will check the cam to cylinder head wear specs like the manual says, but I still need to make sure it's not going to wear anymore.
  4. Hey, I'm in the middle of doing a valve adjustment on my YZ and the cam shaft looks like it burred the cylinder head very slightly between the middle and right lifters. I was wondering if it could be from a clogged oil hole, and if so, how do i check?? Also, would it be alright if i got rid of the burr with sandpaper? Thanks!
