 The
clutch cover casing showing the the original oil filler hole, this
is about 18.5mm diameter at the top which is the correct tapping
size for M20 x 1.5 pitch.

 Tapping
the oil filler M20 x 1.5 so I can have a screw in bung rather than
the rubber push in one. Made an aluminium tube 29mm outside
diameter and a 20 mm hole through the middle, This will help
locate the tap true to the hole.
|
 This
is after the hole has been tapped, just needs a bit of cleaning
up.

 Clutch
casing with the brass oil filler bung screwed in. Have to make a
few adjustments to the bung so it finished screwing in the
correct position.

 A
brass oil filler bung I made in the late 80's.
|
 This is the one I currently have on my bike, made from ally in 2012/2013, surprising how little effort is required to keep the bung looking nice, quick wipe with the cloth after cleaning the casings.
|
 Simple tube,
but does the job.

 Just
finished polishing the left hand side engine casing.
|
 It is worth spending a few quid buying sheets of wet 'n' dry in varying grades from 320g to 1200g, depending on the job I also use velcro sanding discs prior to polishing with the buffing wheels. It helps if the metal is close to mirror polished before using the polisher as save holes being elongated and cornets over rounded.
