Richards newly found race bike.......
Has been taking shape over the winter
of '06/'07 . Since being reunited with it in the summer of '06 he has been busy
restoring it to race-ready condition & to as near its '64 specification as
possible.
Rather than refinish & replate every item it was decided to treat the
bike to a "sympathetic" restoration where parts were left in "as
last raced" condition if at all
possible. In some cases this was possible -
the original petrol tank will retain the dent in its side which was put in it
when Richard dropped the bike loading it into the van in '64. Its internal
condition will be perfect & coated in a modern sealing compound but the
external painted surface will remain with original scrapes & scratches just
as when it was last raced.
The one-piece exhaust pipe & mega was very rusty, dented & devoid
of original paint. Rather than make a new one the original has been derusted
& resprayed in the original heatproof black. It looks just like it was in
'64.
Some parts have had to be refurbished & refinished. The front fork
legs being a good example. The stanchions were rusty & one was seized into
its fork leg. When both stanchions were dismantled it was obvious they would not
be serviceable. It's impossible to buy new stanchions &, whilst new ones
could be
made, it was decided that the originals could be saved by hard
chroming & regrinding back to original diameter. The sliders themselves were
slightly oval in the ID & were ground internally to a true diameter before
being powder coated in gloss black as original
The rest of the rebuild has been tackled in this fashion, if its usable,
safe & original it stays. Unusable but repairable is kept. Only totally worn
out, or safety related, parts have been renewed or replaced with NOS or modern
alternatives.
The finishing of components has to be a compromise between the OE finish
(which often in the case of RMs bike was not the same as the equivalent road
bike) & what the EEC will allow us to use these days. Cadmium plating for
instance is all but impossible to source being a very toxic process, a variety
of zinc plate is as near as can now be easily achieved.
The engine
While the cycle parts were easily recognisable as RMs original factory
built bike the engines which came with it were not & were in a variety of
states.
On the principle that pictures speak louder than words the following pix
will to illustrate the lows & highs of the stripdowns.
The lows.....




The highs.....




The pictures above illustrate some of the wonders revealed as the engines
were stripped - a disintegrated piston, a smashed gudgeon pin, a bent oil
filter, a hammered con rod.....& a 5 speed gearbox!
More as the job progresses.....
