Two totally different power styles. I dont like the yfz cause you have to work so hard to keep it in a good power range (like 2 strokes) where as the raptor just kinda cruises in it but to each his own.

And the 660's frame and geometry sucks compared the yfz, so why would you ever take the yfz engine out of the yfz? And if it's a motor with no home, why not just get a yfz roller?

If you're going to transplant into the 660 I can think of a dozen other motors that would be a better choice.
