To ball hone or to not ball hone a plated cylinder

[SmokinJoe]

I want to share this picture from my new yz250. Right here in the wiseco directions it says in caps DO NOT use a ball hone on a plated cylinder! Hopefully you guys will stop doing it cause your risking damaging your plating.

Correct, a plated cylinder will get damaged using anything that abrasive.
Scotchbrite, hot water, and wd40 to finish it up.

Those look like iron sleeves (I might be wrong of course), and in that case, totally acceptable.

Not trying to start something but how is a ball hone hard on a cylinder and not a brush type diamond hone?

Ball hone will hit the port edges make them chip thats why not recommended.

Just did a new top end a week ago, 2nd one since new. Cylinder still looks brand new, no scratches (except the still visible cross-hatch). 

I sprayed some decarbonizer in the cylinder, ports, PV, etc, and let it soak for awhile, then wiped it down with a paper towel. I've done similar things in the past... For example, brake cleaner and a paper towel. Then I use an air compressor to blow everything out.

Anyway, I warmed up the bike twice for a few minutes once it was back together. Then I ripped it hard at Glen Helen on Thursday. Literally, unloaded, quick warm up, start straight, then first big hill tapped in 3rd, next hill tapped in 4th. She felt as strong as new from the get go and ran hard all day. ?

I'll probably never change my methods.

Just my experience....  It says, "... Do use a rigid or brush type hone..."  

Only reason I've used one is to go 5-7 turns to put hash marks in it to allow the rings to seat properly.  Posted so I can follow.

I use one similar to this, a 3"& 6" blade depending the cylinder size for 30 seconds or so at slower speed. Does well

When running those hones, you need to be careful at the speed you spin it and pull it up /push it down. The faster you puah/pull it, the greater the angle of the cross hatch, and less oil retention...
