How do I indentify what cylinder("A" or "B") I have for a 2001 cr250?

Thanks,

It's stamped on the cylinder. For the life of me, I can't remember exactly where, but it's on there for sure.

As I understand it, the vast majority of them are "A" cylinders.

Do you remember if it's visible from the outside?

I have a cr250 cylinder in my hand, and there are stampings on the righthand side transfer port bulge,,,wish i had the bifocals on,,i thing it is in that string,,there is also a stamping under the reed chamber,,cant make out either with these glasses, but look at those points.

An A piston works well in a B barrel and a B will fit nicely in a worn A for the most part. If I recall there is only about .0004 of an inch difference and it is at the skirt of the piston.

Found the marking. It's near the bottom of the cylinder on the shifter side towards the intake. I have an "A" cylinder. Thanks for the help.
