Hi, I'm replacing the timing chain on my 02 WR426F, but i can't get the flywheel off. I've bought a flywheel remover, but no matter how much I tighten it, the flywheel won't budge. Can I damage the internals of the magneto by putting to much preasure on the shaft it sits on? Just wanted to be sure before I go hell for leather at it. Cheers.
