Updated 12/29/23 Needed application and size for Wiseco 1013RS L Ring

[Mark Loraine]

Wondering if anyone has the Wiseco piston application chart for the old green envelope piston ring number 1013RS I have on-hand.
I am looking for the size of the ring primarily and engine application after.
These will be in the Foreign section.

Ultimately, I need a ring to fit a 50.10 mm Sirio piston I have for my ATK/Atomik Reed 100 cc engine.
Bore size as I recall was 50.18 mm at the top ridge.

I'd take 2 if anyone has them, but lets get the application of the above mentioned ring first please.

Thank You,

Mark L. / SWNY

O K, no takers on that part number.....

How about this one?
Wiseco 1040P and 1050P piston kits/(1040 has been identified as LMR)

my old Wiseco #12 kart catalog doesn't list them, So I suspect it may be old Euro motocross dirt bike applications.

Since the number is in the 1000 series, I was hoping it was kart, but it may not be.

Thanks,

1013 PS is Komet A, 50.8mm bore piston.

Don't see any "RS". Might be ring standard.

Do not see the 1040-1050

Wiseco catalog #9.

Found this. Has a 51.0 on the box.

Thank You Rob, I saw those piston kits but they don't know what they fit either.

Gotcha on the Komet rings !

RS, YES, Rings Standard bore !

Never thought of it but picking up an old Wiseco motorcycle catalog might be handy thing to have. At least you could sell them to the right people because I'm sure someone, somewhere needs them.
