okay - i will feed your hunger for info
and give you here a bit of what may be of interest about my person
first I completed a 3 year apprenticeship in handicrafts - (central heating) bending and welding (o2 & aceton) pipes and so on.
hard handwork all day long.
after this, for a bit more than 2 years i studied mechanical science - no final exam
then i changed kind of studies and my final exam is called "graduate engineer for a/c (air condition), plumbing & heating" as written in my short forum profile under "occupation"
all my knowledge about motorcyles is built by long long experiances in the last 45 years
that means ~ 85% lucky tries with full success and 15% (sometimes very expensive) errors.
never ever i had a motor mechanical apprenticeship .
i lived when i was still very young in a very small village at the country side of germany - only around 500 inhabitants but at minimum 2500 cows plus ... ;-) -as i said - country side
by that all of us were missing a good and payable workshop nearby and all of us where caused to do all repairs ourselfes
first starting with putting plug off at a 50 ccm small bike (motorized bycyle), changing the chain set, and so on ..
doing more and more repair my horizon grew and my talent to look over the "soup plate´s end" was also a big help to become the guy i am today.
nowadays i have arround 70 Gbytes of manuals on a pc in the garage and at home (no. of manuals itself? i have no clue - must be hundreds)
and if i have the manual wich is depending to the "broken" bike i do nearly all the repairs with only one real exception - the need of very special tools. then i have to visit a specialist in a specialist workshop of the respective motorcycle brand.
so this increases further more my experience day by day at all bikes with metric bolts and nuts.
my favorites are 4-cylinder bikes where ever they come from.
for harley´s inch bolts and V-motors i have no tools, so i never try to repair those "inch" bikes.
equal to that V´s i also never ever would touch a ducati - no clue how their correct running is when they are perfectely running.
in german we have a saying (?) :"schuster bleib bei deinen leisten" in english "shoemaker stay with your tools"
and I follow it as best I can - hands off imperial (inch) bolts and V-engines.
no? ask what ever you want :-)
I do not have any secrets.
one more thing - almost forgotten - a kind of philosophy.
my stomach - he warns me if he "thinks" I would fall into some kind of trap.
when i get this strange indefinable feeling in the stomach i stop any work and think about what might go wrong.
about a cigarette later I usually found out why my stomach warned me.
In the few cases (max. 3 or 4 times in my previous life) in which I ignored this feeling, it was always very expensive for me afterwards, because I had to stand up for my stupidity.
very violent example of such a warning.
i actually wanted to cut a curve around a mountain
but my stomach literally screamed not to do so and I stayed on my side of the street.
what can I say - a car came towards me and if I had cut the curve, there would have been a very bad accident.
