GasGas
Pro Carb spacer...
I
featured this a little while ago but Ian Bowers who
makes them has given me some new contact details...
.. This alluminium machined spacer
is a much better replacement for the rubber donut that
sits on the rear of the carb so that the airfilter
tube slips over it. The original one can become dislodged
on the blind side and then you end up with dust and
all sorts of crap inside your engine, and it is amazing
how quick the bore will wear out!!
... these machined items are slightly
longer than the standard one and fit perfectly with
the help of some grub screws.
Available from Ian Bowers for
£22 including mainland UK postage, you can reach him
via:- ian@bowers45.fsnet.co.uk to order or get more
information.
.. you won't regret it, saves
a fortune compared to an engine re-chrome!!... |

First work
on the Beta...
After a bit of an
off at a trial I lost my rear brake completely, turns
out I had moved the banjo bolt enough to loosen it
and let fluid out, or air in depends which way you
like to look at it!! The Beta is a very easy bike to
work an and everything fits in place very well. Here
is the view after 15 minutes work... rear wheel out,
rear mudguard off, silencer and centre box off and
airbox removed...
... and no nasty
suspension linkages to wear out!!. It is also noticable
when washing the bike how much less mud it holds compared
to my GasGas. There doesn't seem to be all the little
traps that get the mud in that won't come back out
again, obviously the linkage being a major area that
is much clearer!!
I modified the carb
as per the information in one of the links above to
move the overflow hole up a couple of mm's. It seemed
to work as i didn't need to top up the tank so often
at the last trial!!
The only thing I
have replaced to date is the airbox to carb rubber
that had a small split in it where a screwdriver had
been used to stretch it around the carb and must have
slipped. Just waiting for some new rear brake pads
and all done.
The only thing i
need to do after each wash is drain the carb out take
the flywheel cover off to allow any water to be dispersed
with a squirt of wd40 type oil. |
Change
of stead!!
Something new in the garage to
learn about!!!.. Heath has changed from the 300 GasGas
to this, as new, Beta 250 Rev3. The only changes I
plan to make for the moment are experimenting with
the flywheel weight fitment and changing the standard
footrests to Hebo ones as they get clogged with mud
very quickly.. the mud has nowhere to go on the Beta
ones but the Hebo's are open at the bottom. I have
adjusted the carb float tags and will shortly carry
out the carb mod as described in the links above to
cut down on the amount of overflow... to stop any over
fuel running across the casings i have put an extra
long drain tube on that exits below the sump shield.
Brian Curran from the TrialsCentral forum has suggested
cutting a small triangular shape hole at the bottom
of the flywheel cover to allow condensation and ingressed
water to escape. He has had at least 4 Rev3's and so
far no stator problems so i will bow to his superior
knowledge!!
As I like to stand out a little
It may get a set of the radycool graffics for the side
of the frame and swinging arm... available from Steve
Saunders.

Time
of year for our annual trip up to breakheart quarry
in Gloucester for the BVM Test day... They organise
for all the importers to bring the new model year
collection down for us to ride, and in one case
try and destroy!!
My car
was full to the brim with Jack, the two Steves,
Rich and myself and we met up with Terry, Steve,
Kev and Phil onsite... a full r2wtrials test squad!!
The format is ideal, you put your name down for
the next slot on whatever bike you fancy and when
you have finished your 15 minute ride you pop back
into the hut to get another one. Between us we
managed to ride almost all of the bikes there so
we can get views on the various machines from the
different levels of riders that we are..
 .. ..  ..
The first
image is Greame Jarvis who was on hand to talk
about the new Sherco's and gave us all a couple
of demo's of his easy and smooth riding style throughout
the day. If you click on
that photo you will get a selection of shots from
his play ride. And if you click on the photo of
Heath (2nd photo) on the Beta you will get his
views on the bikes he rode..
The quarry
that this took place in is situated up on top of
the Cotswolds and is very dry but loose rocks with
a traditional steep tree lined area around it..
the only conditions we couldn't test the bikes
in during the day was deep mud... thankfully!!!
Although we all have our personnal favorites as
far as the makes of bikes go I think it would be
fair to say that their wasn't anyone who hated
any bike... some just felt better than others,
and no two of us had the same overall top three.
I will say that none of us are 4 stroke fans, so
don't take it too badly that we didn't really try
them..
Thanks
as always to BVM
Motorcycles for a brilliant day, that included
amazing weather considering it has hacked it down
with rain for the last couple of weeks, and is
doing so now as I write this!!

Kev or Steve's images above for their thoughts
on the bikes they rode..

Tony's
GasGas engine rebuild now done.. I had a chat with
Kev from gasgasuk about the bearings and seals and
he recommended that I rebuild it with the new style
crank bearing kit. This is a set of longer bearings,
an internal oil seal in each one and 2 'o'rings to
stop oil travelling along the crankshaft or past the
casing. You have to remove the original crankshaft
collars to fit this kit but it does look like a better
set-up... Picture shows old and new in comparision.
The other image shows
the cranks and gearbox back in situ.. all is now back
together but I had a problem.. It fired up for 30 seconds
and then died!! Then it didn't want to go again...
all sorts of things went through my mind, what had
I left out, left undone or misplaced!! After leaving
it for the night and coming back to it on sunday i
eventually discovered that the flywheel key had sheared
in half... causing the timing to be about 10mm out!!!
Bollox! Still, nothing drastic..
We also discovered
that the fan on Tony's bike wasn't working. I checked
all electrical connections and operation of the thermo
switch but to no avail... upon connecting the fan up
to a 12 volt battery I found... that nothing happened!!
Buggered!! Kev had a spare laying around from an earlier
model so I am going to take it out of it's holder to
see if it matches up...

I recieved
this new chainguard from Steve at Trialcast to
try out... It is a direct replacement for the original
but does require you to remove the rear wheel to
enable the rear bolts to be done up....
... As can be seen
by the scuff marks on my swinging arm sticker it covers
the point that your boots touch the chain, causing
wear on expensive trials boots. My one is a 2 tone
finish that looks very cool. Not sure if that is a
standard option yet but if contact them via the web
link above you will get all the latest options and
prices.. tell them r2wtrials sent you!!

The
old, Blue 2003 250 Pro now looks like this. A Keihen
PWK28 carb is on the way over from Canada for it and
that is the last major thing that I will do to it...
I think!
I would love to have
black anodised wheels and also fancy the idea of anodised
black triple clamps and swinging arm. One tip.. if
you have a 2005 pro and the swinging arm graphics wear
off quick replace them with the 2004 ones. The new
ones are paper thin but the '04's are made from the
same sticker base as the tank graphic and puts up with
far more. The side panel graphics are from the 2004
Raga replica but cost the same as the basic model.
I stripped the original
paint off the exhaust centre box with nitromors and
hand painted with a aluminium heat proof paint from
Halfords. Looks almost like the ally 2004 box now but
the mounting lugs don't break off!! |
