Just hope to get some verification here.

My bores & pistons are stock STD bore. I have to bore the cylinders to the first over.

Are these the p/n for the pistons & rings I need ? Does "OS" mean Over Size ?

SKU: 13102-283-000
PISTON (OS 0.25)

SKU: 13021-292-000
RING SET, PISTON (OS 0.25)

I can't remember IF the 292 rings will fit the 283 piston...... Perhaps Bill or one of the UK "bomber" restorers will verify.....(Ray?...Chris?....)

The 283 rings won't fit the 292 pistons, can't remember exactly why, I tried it once and vaguely remember then being thicker.

I am no mechanic but I would have thought the 292 code rings would fit the BB. I have checked my folders today and I see my mechanic
ordered and fitted CB500 T rings to one bomber. Std rings are listed as K0 13011 283 --, K1 13011 292 --, and CB500T 13011 375 --. I see also the 500T Inlet Valves and Inlet Guides also fit so I guess many of the K0, K1 and 500T engine parts are interchangeable.
