Hi anyone, I've torn down a 1994 yz250 two cycle engine only to find a burned piston and rod bearing. The crank case sections are apart. I need to pull the crank. Do I have to use the Yamaha "screw out the crankshaft tool" or is there another method to remove the crank from the right side? I have another spare crank and rod, so all I have to do is swap. Also, is installation the reverse of removal? Any proven methods would be appreciated. Many Thanks!
