Reboring is recovered the cylinder wall is damaged. Damage to the wall is too severe for honing and resolving deep scratches. The cylinder is no longer around, so easily overheats.
The process of a boring reciprocating engine.
Reboring cylinder decreases the noise of the engine. So thus small fuel - low power so thus an increase in mileage. Increase the engine displacement by using rebore.
Rebore can increase the power of an engine. And increasing its capacity. So requires a good deal of research and work.
The usual cost for the boring of the mains is low cost in Sando Automobiles.
