why does the upper piston ring of my SYM dd50 is always broken.
i bet it's not lean because i set it to nearly rich and the plug reading is near to rich.
it had just broke 3 rings.
please help me.
thanks in advance

pictur please and look in your sleeve for abnormal wear or scuffs maybe its hanging up on a port or maybe your getting wrong rings. maybe its a 39mm piston or 40mm piston either way mixing the rings up will result in thus

What is the situation with your cylinder? New? Used?
