Hello.
I tried for Hasting for 82mm B18c with YCP piston (OEM material), But the top ring gap 0.024' are too large and the second ring tighter than the top one. I asked to the Hasting for this issue, they told me just install directly with these gap it will not cause any issue.
But I dont want to tear down again for the ring replacement one more time? I am make sure my bore diameter in spec, piston to wall clearance is 0.03mm

Do you guys have any other brand suggest to me?
I have asked for JE pro seal, but I have not get reply.

 

anybody could help?
thanks

 

.024 isn't bad id gap the 2nd ring to .026 and run it. but other brands is oem honda, npr, wiseco, total seal, je

 

I had the same problem with NPR and oversize oem ITR pistons. The end gaps were way past the service limits new out of the box.

 

Thanks.
even though 0.024 is not bad for the top, I am concern to the second ring is tighter than top, but Hasting told me just install directly with no issue.
I had purchased more set of JE proseal ring, I hope it will fine

 

How to you do at the last?
I have tried NPR and Hasting , they are simple large

 

I have not decided if I will try another brand yet. I would not be happy to have a second set of new rings I can't use.

 

I tell you after my try ....haha

 

I got a set of JE proseal.
they are all in spec ,smaller than Hasting .

 

Thanks I will order them and hopefully I have the same luck as you.
