ALL OF THIS IS TOTALLY UNACCEPTABLE
We only use SPS Re-boring machines that
can bore from 35m/m up to 120m/m.
We have 3 Horizontal honing machines, 1
state of the art Sunnen MBB1660
And 2 Tried and trusted Delapena Speed Hone
And 3 portable Honing Heads.
All of our cylinders are bored from the
base that is the right way! We then remove
the last 2-3 thou of material by honing
the cylinder surface according to the type
of piston/rings used, This ensures a perfect
ring seal, all ports edges are then chamfered
and Exhaust bridges relieved. The cylinder
then goes though a 3 stage cleaning process
to remove all traces of honing past.
You can be sure that as Motorcycle Engineers
we have the right equipment to take care
of your Cylinders and we pride ourselves
on our Workmanship.
