My 04 200 has over 350 hours on it, its time to inspect, clean the top end. I have read so many different Opinions on whether or not to hone the cylinder, type of hone to use etc.. its making me crazy I would appreciate some real life experience instead of opinions. One reputable engine builder says use a hone to break the glaze on the cylinder, he recommends a ball style hone. Another engine builder recommends a break cylinder type hone with the rectangular stones. He says the rectangular stones wont get stuck in and damage the ports. Quite a few say don't hone the cylinder.
I used scotch brite on my 88 cylinder. This method never really broke the glaze and I didn't get the desired cross hatch to help the rings seat.
Help me out oh wise ones!!
Type of hone?

Your cylinder is coated, for that reason only go over it lightly with a scotchbrite pad. Do not hone it unless you want to ruin it.

Sorry...you asked for 'real life' and not opinions...this is sort of 1/2&1/2..
I got a used cylinder from FRP. It's apparent that it has been honed because I can see the hone marks the same on the top as on the bottom of the cylinder.
Also, it appears to have been honed by a stone type tool, 'cuz the hone marks are 'straight'.
EG says it's OK to hone a plated cylinder..but he does NOT expressly state that for an electrofused (Kaw's oem method) cylinder.
Again...apparently Mr. Fredette doesn't have a problem with doing it.
Glad to contribute to the craziness!!
....like you need a reason?

The machine shop we use has ball honed plated cylinders for us in the past. We haven't had any problems yet. The ball hone is not supposed to be able to take off any of the plating. The "stone hones" typically are not recommended as they can and will take off plating if your not careful. We have not sent any electrofused (Kaw's oem method) cylinders to the machine shop for honing. Not sure if that make you more or less confused?

The problem with honing is it chips the plating around the ports... do it if you wish. Also, it may not be as big of a deal on a "fresh" plating either.

Yeah, ball hone only for a plated cyl....That's what I've heard anyway. World of powersports honed my WR's cyl w/ a ball hone to clean up some scratches in my plating. They stated that it was a band-aid in my situation(this was obvious), but that they do lightly ball-hone the plating on all cyl's when they do a top-end. I personally have used scotch-brite on un-damaged plated cyls, and they come out fine. You don't need to see a cross-hatch pattern to get good ring-seal on a plated cyl, but 'breaking the glaze' is a good idea. Steel sleeves are a whole 'nother story...
