What's everyone's favorite hone for your cylinder? I assume flex hone but I just want to hear some opinions if anyone knows the part number for the right size flex hone I need for my blaster cylinder it'd be greatly appreciated
 
Depends on your bore size 10% larger than bore works for me you will also need to decide the grit... I like flex hone on 2 strokes because it doesn't snag ports. Others with more experience probably use the others with success.. Actually here is a link I ran across a while ago.. it may help you out..

Man, this 2 stroke world is so new to me. I always just use a drill and the hone tool on everything (4 stroke). Never even thought about messing those ports up. I have a lot to learn about 2 strokes!
 
In my opinion ... I use either a sunnen, or ammco positive pressure hone mounted in a drill. When you do it by hand (drill) , you can feel the "cut" as you proceed. When you do it this way, you can check your work often and get it spot on. A positive pressure hone works in principle the same way a auto adjusting cam chain tensioner does in a four stroke engine. It will only go one way and not the other. This way the cylinder is forced, or honed into a round shape (which is what you want for a good ring seal) instead of riding up and down in the "out of round contours" that the cylinder will have from the wear that you are trying to correct in the first place. Just my opinion. Don't rely on a flex hone to chamfer your ports. Take the time to do it correctly. Either by hand with a file and sand paper, or with a die grinder. No hack job crap here. Take your time when chamfering. Once again... my opinion.
 
So is the flex hone a good way or is the sunnen style best? I'm just looking to break a little glase I can still see most of the cross hatches I just want my rings to have a fresh seal. If I get the flex hone what grit will I need for namura rings I can't find the material they are made of any where
 
A flex hone / ball hone will do the job applying a cross hatch pattern, but I would only use this method if I knew that my cylinder was within specs. In other words... taper, out of round, piston to cylinder clearance, etc was within specs. A quick 5 to 8 second burst with honing oil is all you will probably need. Be careful and chamfer the ports by hand when your done.
