Hello as the title states I need to swap out the piston on my 01 cr,I just noticed a crack about 1/2 inch long on the skirt thru the exhaust port.I haven’t pulled the cylinder yet to see if it’s scored.The bike ran but I bought it in need of some love and haven’t ridden it.Ive read mixed opinions about replacing with an Oem piston ,some like wiseco better because it’s forged instead of cast.Anyone have any opinions on this?thanks..
