hello everybody,
is it possible to increase compression ratio of engine , if it is so then how we could do this for e.g i want to increase compression ratio upto 12.5:1 from 9.1:1 of my bike

There are several ways to increase the compression ratio of your single-cylinder engine

1. use a domed piston,
2. increased the stroke,
3. change to a head with a smaller combustion chamber,
4. Shaving the head or block of your engine,

Higher compression ratio generally puts more stress on the piston, the connecting rod and bearings. We can't just assume that they will take the extra load, but must be very careful to build up the rest of the engine as needed.

Sometimes, just going with a thinner head gasket (if available) is a poor man's way to increase compression.
