Hi. I would like to get some honest opinions and feedback on these namura pistons. I have tried 2 of them. One in a blaster and now one in a 300ex.
If I remember right the blaster is .020 over but 300ex is stock bore. I rebuilt the blaster a year ago and it seams to be doing fine. It's not been rode all that hard. Just normal trail riding. But the piston is holding up good so far. I just installed the Piston in the 300ex and I'll update as I know how it's going to act. So far it's doing ok. Keep in mind I have not gotten it broke in yet. Any way If any else has used them I'd like to know how they worked. I contacted namura both times I installed the Pistons and they got right back with me via e-mail. I asked them about putting instructions with the piston like others do. They said that they will soon include instructions like wise co and others do. They also told me the piston has the same tolerances and specs as a factory piston. Any way I'm not biased. I'm just letting every one know how it's going for me. I have tried wiseco and pro X pistons and they both worked good as well. We will see how this works out.
