namura pistons stink

[smreinert]

i just put a namura kit in my trailboss 250 and rode it around the house 4 times and the rings are toast. anyone have any info on these?i just ordered a pro lite for it.

[ONLY2STROKES]

nope.i must ask though.was the bore honed and within specs?

[MI_2Stroker]

Sounds more like an installation issue instead of the piston.

[Ed Gein]

Namura's are recycled Chinese pop cans.........stick with Wiseco......

[ONLY2STROKES]

i agree that the namura is cast and not as good as wiseco.but the rings shoulda help up longer than that.

[ky 2stroker]

yea id say that there was somethin else that caused the rings to wear out. although I've heard both ways about namura pistons. you get what you pay applies to this I think.

theres another issue

[project_Tecate]

how are the rings toast? Did you put them in correctly?

[strokeittwice443]

if the rings were upside down or not lined up with the locator pins i could see that happening,or if the cylinder walls were scarred pretty bad from the previous piston. i have used namura pistons and they didnt fail but according to some on here i guess i was lucky.

Namuras a junk pistons. Like ed said stick with wiseco.
