stick with the oem and ya ride more then 200 hours on a cylinder with some decent oil and a vertex piston but in the end the choice is for (C)oal(R)egion250.

I doubt Honda/OEM makers are actually casting cylinders for bikes of our era. They probably aren't doing production work for our bikes (05'-07') anymore. Economically unsound. The molds/dies, etc. have likely been outsourced, and Honda just stocks them for resale. The cross-hatching was very uneven on the "new" OEM cylinder as well.
I have some pics, so stand by as I upload them. The "Expert" at the major parts vendor said, "Ah, ain't no issue" and no return authorization cuz they ain't getting any better than that".
I called Bullshit and made them take it back. If I had an opportunity to inspect it firsthand, I wouldn't have purchased it.
Your call... I have a spare cylinder in solid shape. Going to Millennium. I'll dig up some pics of a cylinder that was done a few years ago by Millennium on a clapper, and I am still running it. Old OEM, rebuilt for me henceforth.
Honing appears sloppy and very uneven?
Pay your $, take your chances. Just my $.02.
Watch your squish via torque and base/head gasket thickness. ALWAYS MEASURE. Refurbished units suffer deck wear during cleanup.
What a joy it is. Best $$$ I have ever spent. Super easy to dial in.
Forgive me Jesus for the "Tusk" shifter thingie... Moment of weakness/stupidity while online. OEM is great.
Point is that, in my estimation/experience the poor quality of the OEM cylinders being offered today for bikes over 10 years old aren't my preference. Good Luck with your family!
Also, post from "40" member fellow in this thread on 1/23/2018 10:48 AM
He is SPOT ON in his analysis, especially his aversion to silicone in an air box anywhere.. Gas/gas fumes will decompose the shit out of it and you'll suck it into the carb/engine. NOT GOOD. One of the finest and most accurate posts I have read on this site ever concerning Honda 2T air boxes and engine health. Thanks, "40"!
Ride safely!

Seal All clearly states "gasoline and oil resistant" which makes it suitable for this application.
Click on the photo for a better view.
There are likely other sealants and adhesives available on the market that are also gasoline and oil resistant, however we have had good results using this one.
You will probably not be able to find a similar level of gasoline resistance in commonly available silicone.
Silicone is not suitable for this application.
