I have never had any issues with them, maybe thats because the leave rpm has always been 6,000rpm and up

Yes they do smoke some until gas loading at higher rpm, have noticed this

I have tried just about everything out there, and for my money I choose the 5/64 back-cut top and second ring with the low tension oil ring by Tri-City Competition Service, for a stocker motor that is with the 5/64 ring lands. Call Greg Luneack @ 760-630-9094 He will fix you up, and he is a great guy to deal with.

Jim,

Thats the kit with the gas ported spacers and thin narrow rings below the spacer , all in the 5/64" groove ?

Anyways the engine im doing is not a stocker so i can go with any ring i wish. You use the .8mm or 1.2mm ring with the spacers ?

The 3 rings i listed were what i thought about going with

Hey, maybe the 5/64" groove with gas ported spacer will knock some weight out ?????????

Thanks for the contact info

.043 With lateral gas ports.
.043Napier second ring.
3mm oil is good
The key to the whole package is a good straight hone with the correct profile.

Good Luck

Napier second ring with twice the end gap as the top ring. Eliminates top ring flutter.
Remember: This type of ring as with all secong rings is for oil control only hence the larger end gap.

Use fish scale and drag the whole package @ 7 lbs.

Good Luck

Vertical gas ports ?

Vacuum leak on the intake stroke, not so... look at the top ring after run and you will see wear mark on the bottom inside whare it seals on the intake stroke... also second ring, especially napier not only controls oil but its reverse taper face aids the intake charge...

Sorrt trmnatr, I should have completely read your post before I jumped in with my 2 cents worth.
I was talking about a stocker motor that had to use 5/64 ring lands.
I'm sure you would probably want to use something different for what you are building.
Good luck.
