1. CYLINDER BORING
Boring the cylinder block will be required when using our piston kit. As our piston kit will be at least 0.5mm oversize
from stock.
① Check that the piston to wall clearance is within the recommended
clearance values.
② Have the Cylinder block bored to suit.
Always use a Dummy Head (Torque plate) when
you have the Cylinder Block bored.
③ Once Cylinder Boring has been completed, use the
Cylinder Gauge to verify that the clearance is within
the required values.
④ You'll find unwanted course edges at the bottom of the cylinder bore
after boring. Remove all metal shavings and rough edges, and then
chamfer approx R0.3 with a file or similar tool.
