1966 type 1 were either 1194cc which was 77mm with 2.5mm top and oil ring1300 was also 77mm but with 2mm top and oil scraper ring
1500 was 83mm with 2mm top and scraper.
However, you need to pull the engine apart and measure because you never know what has been done to it.
You have to disassemble the entire engine, remove the piston and check the rubber ring around that piston.
more heat is generated in working of engine so its piston ring war out and cut mark appears on the ring surface.
You mean a piston ring. It seals the gap between the piston and the chamber in your engine
If you only use one piston ring on 80cc bike engine, the compression ration will be reduced.
The "D" on a piston ring typically indicates the cylinder bore diameter for which the ring is intended. The "N" refers to the ring's position on the piston, such as top, middle, or oil control ring. Together, "D N" specifies the ring's size and location within the engine.

The piston ring groove serves as a seating area for piston rings within an engine's piston. Its primary function is to maintain a seal between the piston and the cylinder wall, preventing the escape of combustion gases and controlling oil consumption. Additionally, the groove allows for axial movement of the rings, accommodating thermal expansion and ensuring proper ring function during engine operation. Proper design and maintenance of the groove are essential for optimal engine performance and longevity.
Yes, the material, thickness and possibly style of piston ring(top ring) can be different.
On the pistons, in the block. If they are bad, it's time for an engine rebuild.
Nip clearance of a piston and ring refers to the gap between the piston ring and the piston groove, which allows for thermal expansion and proper sealing during engine operation. This clearance is crucial for ensuring that the piston rings can expand as they heat up while still maintaining enough contact with the cylinder wall to prevent blow-by and maintain compression. If the nip clearance is too tight, it can lead to ring binding and excessive wear, while too much clearance can result in poor sealing and reduced engine efficiency. Proper nip clearance is essential for optimal engine performance and longevity.
Because of Ring burnt, engine heat-up or loose piston in sleave.
The three main functions of piston rings in reciprocating engines are:Sealing the combustion/expansion chamber.Supporting heat transfer from the piston to the cylinder wall.Regulating engine oil consumption.
