CAPTAINS REPORT
Busselton Mid-Week Run 15/7/15
A disappointing turn up, only 5 riders turned
up, one of them from Bunbury. Darryl came
down to see us off, as he is still on the no ride
list, his Medico says it could still be a few
weeks before he is fit to ride. It was a very nice
day, clear skies, no wind, although a bit cold at
first. John again lead us off over to Kirup via
the Vass Hwy. and Cundinup Rd where we en-
joyed coffee & pies.
We then headed off to Capel via the Upper
Capel Rd and Goodwood Rd where we had an-
other coffee, then heading back to Busselton
via Stirling Rd (John was going to take us
down Mallokup Rd but he got ahead of us
when we crossed Bussell Hwy.
He said he was standing on the corner but we
didn't see him, so we were trying to catch him
up all the time he was behind us!) Ludlow Rd,
Tuart Dr and Layman Rd arriving back in
Busselton about 1PM a very nice ride.
P.W.
Midweek PM Ride 15-7-15. 12 Riders
Last ride before we leave on our cruise. I
stayed home while John P. led the group thru
Dardanup West, Crooked Brook, Dardanup and
back to Eaton where Kate C. and I had after-
noon tea waiting.
Sorry I didn't plan a longer ride especially as
the weather was fine however I hope the toast-
ed sandwiches made up for it. After quite a few
discussions the group left about 330pm. Thanks
to Kate for helping once again.
Busselton Midweek Ride 05-08-15
10 Riders
A cold clear morning greeted us with no wind.
10 bikes attended, 2 from Bunbury with one
passenger, there was 3 club eligible bikes. John
again lead us off along Bussell Hwy, L into Tu-
art Drive, L at Ludlow North Rd, R into
Mallokup Rd to Capel from Capel we headed
along Gavins Gully Rd, L into Boundary Rd R
at Lowrie Rd, R at South Western Hwy L
5
into Argyle Rd, (I left the ride hear to return
to Busselton for Doctors appointment at
11:15) L at Hurst Rd through to Boyanup for
morning tea.
From Boyanup the ride headed along Bo-
yanup West Rd. L at Elgin Rd R at Gavins
Gully Rd to Capel for refuelling stop, then
headed down Goodwood Rd, R at Capel Tu-
tunup Rd, R at Tutunup Rd, L into Ludlow
Hithergreen Rd, R at Princefield Rd, R at
Wonnerup South Rd, across Bussell Hwy in-
to Layman Rd to Sensation s Cafe at Port
Geographe for a light lunch, where I met up
with the group again.
Thanks to John a good ride with no mis-
shapes and to my knowledge no one got lost.
Peter Whiteside
Country Run 09-08-15. 11 Riders
The Ride started on a chilly morning from
the Entertainment Centre and meandered
along Ocean Drive, Washington Avenue,
Roberts Road, Ludlow Road North, and Tu-
art Drive.
Then onto Bussell Highway, Sues Road,
Vasse Highway, Ludlow Hithergreen Road,
Tutunup and Goodwood Roads to arrive at
the Capel Bakery for Morning Tea.
On the narrow Bridge on Tutunup Road there
was a set of Traffic Lights directing the traf-
fic to just one lane across the bridge.
When Bill Pike stopped at the lights he had
trouble restarting his newly restored Match-
less Bike.
After several attempts and realizing that the
decompression lever was jammed they final-
ly got it started again.
Bill continued on to the Capel Bakery with
the rest of the riders.
At the Capel Bakery several of the riders said
that they would not go on a run again if it
was along Tuart Drive because the road is
too narrow, bumpy and dangerous.
Bill Pike had trouble starting his bike again
after leaving the bakery; he also noticed that
several bolts had fallen out of his Bike’s seat.
Bill and Matchless travelled back to Bunbury
in the Back-up.

Bill reminded members of the Margaret Riv-
er Show on Saturday 17th October and the
Brunswick Show on Saturday 24th October
this year.
We want to make a great representation at
both shows so please contact Bill if you are
able to take your Bike to either or both
Shows so that he can organise a display.
The South West Veteran Car Club is or-
ganising A Motoring Heritage Day which
will take place on Sunday 15th May 2016 at
The South West Institute of Technology.
(Bunbury). This was formerly the Bun-
bury TAFE.
The Heritage day will incorporate Bikes,
Cars and Trucks and it is hope that there
will be enough interest generated so that
the Heritage Daye will not be shifted to the
Metro area due to lack of interest. Please
contact Bill Pike if you are interested in
taking a bike early, so that he can reserve
a good position for a display.
The Institute has a state- of- the- art Auto-
motive centre with 600 on campus car
parks (some under cover), and additional
car parking nearby.

LICENSING LIAISON OFFICERS RE-
PORT
Jeff spoke about the proposed no fault
6
insurance scheme, and the letter of protest
sent to the ICWA by Peter Boreham the Secre-
tary of the CMC.
Anecdotal evidence suggests that the accident
rates for historic vehicles are so low as to be
almost non-existent. We could find no evi-
dence that anybody had ever received a cata-
strophic injury in an accident in a historically
licensed vehicle in WA.
It is the view of the CMC and its member
clubs that there is no justification for a 115%
increase in third party insurance for historic
vehicles and that any increase should be lim-
ited to a maximum of 35% ($9.06) in line with
the percentage increase in fully licensed vehi-
cles. If future statistics indicate that the does
not represent the accident risk of vintage vehi-
cles, then the premium could be reconsidered
at that time.
Given the number of historic licensed vehicles
in WA, the $30 premium is only likely to rise
in the order of $150,000, which is not signifi-
cant in terms of the State’s total budget. How-
ever, for the many older enthusiasts who may
possibly rely on a pension or fixed income, the
additional insurance premium can become bur-
densome. This is exacerbated as many of the
owners of vintage vehicles often own more
than one vehicle, due in part to their dedication
to the preservation of Australia’s movable her-
itage, and it is apparent that the unjustified $30
increase will impact adversely on many of our
members.
Jeff also mentioned that if you buy a bike from
interstate you can no longer ride the bike home
on an interstate permit.
All other states except WA only require a med-
ical for licence renewal. It appears that our
state is discriminating against older drivers,
and there is no evidence that older drivers are
in more accidents and therefore there is no rea-
son for the discrimination.
As a Club we need to address the issue.

GENERAL BUSINESS
Bob welcomed new member John Feltham into
the Club.
Ron Gill is currently in the Restorative
Ward at BRH and would welcome some vis-
itors from the Club.
Ted Bailey is having trouble getting his motor-
cycle licence renewed, because of Department
bureaucracy. Ted apparently went to take his
test on a B31 motorcycle and was told he need-
ed to take his test on a modern bike. There is
no legislation to dictate what bike you ride for
a motorcycle license test. Bob suggested that
as a Club we contact John Castrilli to help out
in such cases.
Bernie McCormack has a Norton lay down
gear box for sale; the asking price is $1,000.
Murray Rudler is looking for a BSA flat top
fuel tank cap; if anyone has one or knows
where Murray can get one please contact him.

Tuning:
There are four adjustments that can be made to
the concentric carburettor. The adjustments
should be made in the following sequence with
the engine at operating temperature. The bike
should be in operating setup (i.e., Exhaust sys-
tem installed, air cleaners installed, etc.).
1, Adjust the Main Jet (Throttle at three-quarters
to full open).
2, Adjust the Pilot Jet. (Throttle up to one-eighth
open)
3, Adjust Throttle Cutaway. (Throttle one-eighth
to one quarter open)
4, Adjust Throttle Needle. (Throttle one-quarter
to three-quarters open)
5, Readjust the Pilot jet.
The adjustments for each or the five steps are
described in the next section.
How The Carburettor Works:
Throttle Setting, Full Closed:
The carburettor proportions and atomizes the
correct amount of petrol with the air that is
drawn in by the engine. With the throttle slide in
this position, the engine is idling, the needle
valve is shut and the pilot jet and air adjusting
screw control the mixture.
Tuning:
With the engine set at a fast idle, the twist grip
shut off, the throttle valve down on the throttle
adjusting screw, and the ignition timing correctly
set:
(1) Screw out the throttle adjusting screw until
the engine runs slower and begins to falter.
(2) Screw pilot air adjusting screw in or out until
the engine runs regularly and faster.
Carefully repeat these two adjustments to obtain
the best slow running
Throttle Setting, one-eighth to one quarter open:
10
When the throttle is opened from the idling posi-
tion, the throttle increases the amount of air in
the mixing chamber and the needle valve begins
to open, this proportionally increases the amount
of petrol.
Tuning:
In this position the air is controlled by the throt-
tle cutaway. If there is spitting from the carburet-
tor, richen the mixture by fitting a valve with
less cutaway. If there is no spitting but the en-
gine jerks under load. Then a larger cutaway is
required to cure richness.
Throttle Setting, one-quarter to three-quarters
open:
The jet needle controls the amount of petrol
through a wide range of throttle opening during
acceleration. In this position the throttle cutaway
is no longer controlling the air.
Tuning:
If acceleration is poor but improves with the par-
tial closure of the air valve, raise the needle. If it
becomes worse try the effect of lowering the
needle. Experiment to find the most effective po-
sition.
Throttle Setting, three-quarters to full open:
The throttle valve is now fully open; the petrol is
no longer controlled by the needle jet but by the
main jet. And maximum power is developed.
Tuning:
If the engine runs heavily' at full throttle the
main jet is too large. If the engine appears to
have better power when the throttle or air valve
is slightly closed, the main jet is too smell.
How The Float Chamber Works:
The level of petrol in the float chamber is at
maximum level, the float has risen and the nee-
dle is located on its seat, sopping petrol from
flowing into the chamber
When the level of petrol in the float chamber is
low, the float drops and the needle is lifted from
its seat, allowing petrol to flow into the chamber,
petrol being gravity fed from the tank.
Several articles have been published about set-
ting the float level on Concentric Carburettors
and this is a summary of the important points
from people in the know:
The actual specification, from the engineer who
designed the Concentric Barry Johnston, gives a
gas level of between .170" to .240" below the
top edge of the float bow, 170” being rich
and .240" being lean.
This level has a dramatic effect on the running
of a properly tuned motorcycle. It pays testa-
ments to the design of this carburettor that the
range of miss-adjustment it can tolerate and still
have the motorcycle run, if only poorly. It is sug-
gested that you set the float level first before do-
ing any carb adjustment.
The level can be estimated by placing the round
edge of the plastic float between .060" and .090"
below the edge of the bowl when the needle is
depressed by a slight force on one of the float's
needle tangs.
You can turn the bowl upside down to establish
this. With the float above the top of the bowl, as
described in the Norton Tech manual, the float
can contact the bottom of the body and not allow
the float needle to seat firmly.
It also makes the carb rich through the jetting
range. With the float, level with the top of the
bowl, although not as rich as when it is above
the top, it is still out of the specified range.
The brass needle seats are installed and adjusted
cold by the factory. Using a proper sized drift,
you can adjust the brass seat on a solid surface.
