Spotted an exhaust spring on the floor; on investigation found 2 had broken,
port
outside front and starboard inside front. Changed them and had a good inspect
but only just noticed a small line near the top of No 4 downpipe (rear port).
On closer inspection, and removal of the small carb bowl shield I had wired
onto the pipe, to my horror I saw the crack went 3/4 of the way round the back
of the pipe up near the bend (I have seen other reports of this). I had
wondered
about the general discolouration of engine frame etc. around that side of
the engine. It was just so hard to spot. I thought the engine had been sounding
a little different and maybe it was a contributing factor to a couple of hicks
i'd had recently.
New item ordered from CKT and fitted (said 4 on the new flange but 1 on the old
one).
