2012 RMZ 250 Engine Ticking

Recommended Posts

Hey guys,

It's been awhile since I've posted.  I ended up buying my son a 2012 RMZ 250.  He was having problems getting it cranked when it was hot.  For example if he fell over in a race.  He would wear himself out kicking it.  I put in a new piston.  Got it back to top dead center.  Timed it with the cams right.  Fired it up.  Heard a ticking noise.  Figured it was the cam chain because of what I had read.  I ordered a new cam chain and Stage 1 cams from Hot Cams.  Now I don't know what to use to get the magneto rotor off, which is what the manual calls it.  I assume I can use a flywheel puller.  Does anyone know.  I also don't know what to use to hold it to torque it back down when I get the new cam chain on.  Any help would be appreciated.  I guess what I am asking is what tools can I use to take the magneto rotor off and put it back on.
