| Mio bore up series |
Want to do a bore up on the motor Mio, Mio, Mio Soul, Mio Fino and other variants without enlarge the crankcase can be done. What is important is that the liner thickness is sufficient for daily use and installation of the fitting. Advantages like Mio machine itself is a hole that is wide crankcase. In addition, it should replace the liner to adjust the diameter of the piston is used.

| crankcase hole diameter approximately 63.46 mm |
Read crankcase hole diameter 63.46 mm on the digital calipers. Thus, for the larger bore up Mio without crankcase can use a liner which has an outer diameter of 63.46 thick - 1 = 62.5 mm. It was his only liner and piston diameter is still his.

| 1.5 mm thick safety boring x 2 = 3 mm |
Boring or liner itself must change to adjust to the diameter of the piston. If you want to use a 58 mm piston as belonging to Sonic, the outer diameter of the maximum bore of 62.5 - 58 mm = 4.5 mm thick and divided by two as the left-right boring is 2:25 mm. If you want to oversize liner boring or earlier, then the maximum size is at least 1.5 mm thick boring left-right, ie 62.5 - 3 = 59.5 mm or 150 oversize piston Sonic.
