A/B/C marking on cylinder (pic)

[MNKeith]

Easy question but I never found a clear answer, just want to be clear before I order another piston.

Is the circled spot below where the stamped cylinder size is located? It's marked "A" on mine so I assume so...but ya know...I don't like to assume.

I am planning on buying a Wossner kit this week, am all ears if anyone has other suggestions.

Yes, that is correct. There was another thread on this subject. That is the correct location and my bike has "A" cylinder like yours.

Thank you! I have been reading a lot of posts here, must have missed that one.

Follow up... Is there a crossover for the upper conrod bearing (the caged roller bearing)? Will the CR250 work? Any particular year?

 

[Jakobi]

The little end bearing is 18x22x21.8

Same CR250 pre 2007, or even a current model YZ250 by the looks (http://www.serco.com.au/bearing-218mm-p-16885.html)
