Yz cylinder dowels?

So I am rebuilding my 2014 yz 250 two stroke. I have the piston in and the cylinder cleaned and measured and everything. One thing I'm wondering is if it is normal for there to only be two dowel pins for the cylinder to slide over. The two that were present were on the foot brake side.. I looked in the manual, and while it doesn't make much mention on the dowels themselves, all the exploded photos I've seen show only two. Anybody know for sure that this is right?
