Yeah fair enough George. I can relate to a lot of what you are saying.
I also know that brake failure is bad for your health. Time bombs like
using the wrong cleaners, wrong fluid, leaky joints, contaminated
fluid (air or dirt et al) are all things that all too often creep up
on you when you least expect them, ask anyone who has spent a decent
amount of time in a repair shop. Then there are the mistakes that are
just plain expensive like incorrect assembly, mis-wired electrics...
I learned a lot of what I know through trial and error too, but I
suggest that things like brakes should not be treated with cavalier
arrogance (and ignorance) as suggested elsewhere in this thread.

What?

it is now 2010. 30 years ago was, I regret to inform you, 1980.
Rather a lot of motorcycle mechanics around in 1982 when I started
riding, can't believe they all sprung up in 2 years?

Even 40 years was 1970. Now it might be that there weren't massive
numbers of motorcycle shops with mechanics in Oz then, but considering
there were ones in the 1920s there had to be some.

Hey Theo, when did Ted Stolarski start? Pitmans in Adelaide dates
from at least the mid 70s, ditto The Bike Factory. I'm pretty sure
Central had been in business since the mid 50s.

Then there's all the ads in my early 70s copies of 2 Wheels for shops
and people offering service.

Even in country towns!

So better sigh, count the grey hairs, and change the whine to "50-60
years, in country towns"

(Because in those aforementioned 70s mags are ads for places
announcing they've been in the motorcycle business for 20 years...)

When I was living in Unzud in the 1960's the local bike shop in Petone
had started just post war , the same owners until the retired around
1970 and several of the larger shops in Wellington had traded from the
1920's. I would expect the same in Au

I bought my first Guzzi from Ted in 1976, but he was supplying
scooters (real Italian ones) to Perth City parking Insoectors for at
least 15 years before that.

I can't agree with that Zebee. My country town, Northam, with a
population of 8000, had two motorcycle shops, both with excellent
mechanics, in the mid-fifties. That's 65 years ago and they were both
well-established businesses.

I witnessed a sidecar race where a rotor shattered at Wanneroo
raceway. The outfit didn't make the corner. I spoke to the driver
afterwards, John Bertina, I worked with his Brother Hans for 25 years
at NCR.

Pal & Panther in North Perth has been in business for three
generations, since 1928.

Maybe I should have explained what I meant,
I presumed everyone would understand
although there are some who don't want to understand or even try to

What was meant, was that 30 - 40 years ago,
there was no fully qualified motorcycle mechanics around, they were all self
taught and learned from their experiences.
Ands by fully qualified, I mean Trade School taught,
there was no official training course for motorcycle mechanics.

There may have been motorcycle shops and motorcycle repair shops, but they
didn't have full Trade School training

**************

That was luxury to ride in an outfit with hydraulic disk brakes
I learned on a pre-unit Triumph with drum brakes and the luxury of the day,
was to have twin leading shoes.
