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.
