pistons

[foxrider603]

So I just ordered a set of namuras anybody have any good or bad experience with them?

[Hazzard Racing Customs]

worked great for me man rode a couple seasons on them to good luck with the rebuild bud

[foxrider603]

Thanks they should be here by Tuesday , what did you do for your break in period with your namuras

[oldskool]

Never had any problem with them

I personally don't use them when u can get forged wiseco's for a little more. My experience and knowledge come from my polaris background. The skirts would break and that's never a good thing. Hopefully it's just limited to those and not the banshees.

there's been guys who have shattered the skirts off the namuras in banshee's also......the namuras are the pistons that came stock in the banshee straight from the factory.  That being said it is all about how the cylinders are bored/honed to keep the namuras from shattering.  They have to be bored to their correct tollerances for cast pistons.......way different than machined for forged pistons.

I've seen pics of broken forged skirts to, so ..............................

All piston are capable of breaking. A sloppy bore will guarantee piston failure and cast pistons are gonna give in first. I recall a bad batch of wsm piston last year. They looked fine but the ring landings weren't cut correctly at the factory. Quality control is something of the past.
