CRF's Only Forums

Hello, I am Brazilian and buy parts for my CRF 250R 2006 in US.
My mechanical said I need to buy a piston "size/kind C".
It make sense in portuguese, but I don't know how to specify it in english.
A new bike uses size/kind A, then when it is getting worn change to B, then to C so on.....
Does anyone can help me to specify size/kind C in english?

Does anyone recomend a good shop to buy inthe internet?

Bem vindos Zeadolfo,

Standard size 78mm (Brand new)
1mm oversize 79mm (bore and replate)
2mm oversize 80mm (sleeve)

Thanks ~

Do you know what is the size (oversize) of the kind C?
If I buy the wrong one, does it really matter? Can I assmbly the wrong size?

Thanks,

The "kind C" would be the 80mm.

Is your mechanic going to install a sleeve in your cylinder?

I am not sure if he will use sleeve, but I check it out and tell you.

Thanks
