Namura Technologies Pistons

Anyone ever use these? Or know how they hold up or should I just get Wiseco pistons?

[Big Blue]

Dont take the chance just buy wiseco.

[platinumjason]

Yeah thats what I did. I just saw them on ebay while I was looking for a new top end a thought I would ask if anyone had any experience. Look like good pistons but I dont wanna be the one to find out wether they're good or not.

[Big Blue]

From what Ive hear they arent very good pistons, seem everyone that has had problems with them the piston has broke.

[DIRTMAN350]

Stick with wiseco's. They are tired, true, and tested. I have heard form others that those pistons are junk.

[batoutofshell]

those guys get kickbacks from wiseco!! NOT!

You can put that grey coating on a set of wisco pistons your self. I did these while I had them out of my banshee.

 

The top is also a heat reflective coating.

why would u do that?? as far as im concerned you just added some thickness to your piston skirt...

[fast500#12]

i run them and haven't had a problem yet. i have been running them for about a year, and i don't ride easy ever. nice penguin cups by the way.

There isnt that much tickness added. It is sprayed on with an air brush. One ultra fine coat. Like a film of oil. Most calipers probably are not accurate enough to measure the thickness of the coating. I put it on there because it is an oil retaining coating. Helps hold the oil to the piston skirts.

 

Here is what tech line has to say about the clearances.

Techline coatings FAQ Webpage

WHAT ABOUT CLEARANCES?

The dry film lubricants will burnish as they run until they are no longer visible. They are applied at thicknesses ranging from .0005" to .0015". However, before assembly the coating may be burnished back to less than .0002" with gentle buffing using "Scotch-bright" or similar material.NO CHANGES need to be made in clearances due to the use of these coatings, though in many instances because of the reduced part temperature and increased lubrication tighter clearances may be run.
