'02 KDX200 has "A" stamped Piston need confirmation
Posted: 12:03 pm Jan 21 2013
Hello everyone, This site is awesome. I apologize if this is covered on the site somewhere already. I have searched for my exact question/issue. I have a newly acquired like new 2002 KDX220 and I am pumped about it. It's been well taken care of and I've only ridden it once. I want to make sure the "grenading" piston issue is resolved. A ridding buddy and i pulled the top of the head last weekend and the piston has "A" stamped on it. We are guessing it's the original piston. Would this be a correct assumption? I don't want to take any chances so I am ordering a new Wiseco STD bore piston kit for it. I don't recall ever seeing letters stamped on the top of any wiseco pistons I've worked with before. Regardless, it seems a small price to pay to make sure I don't have the factory piston which could blow on me with such a nice bike. It's completely stock and I plan to change the fork springs and lower it a bit for my short legs. I appreciate any tips on the piston issue. Thanks
