What does anybody no about siming the head on a mxz 700? is it worth it and what about realibilty?man i would just like to get a littel more out of her. isaw some good post onam snow but trust the opions here more.

I have the same question.

It can be some of the best gains for the $$$ that you can find. You have to have your factory head re-shapped or an aftermarket head (which I would recomend) to bring compression back up. You are looking at between $200 and $400 for the whole setup. Also, while it is down, I would look into a set of Cudney pistons, they hold up better than the Elkos.
