For some replacement systems we indicate model years of the bikes the
systems should fit.
Quite often we get questions on this, such as "my bike is a year
later will it fit?" or earlier or "what you say is not true, i
Behind such questions is a real problem:
There is next to no information from the manufacturers on the ignition
system. Most data sheets just ignore this. and if there is mention than a
mere "12v alternator" or so.
Nearly all our info comes from customer and web - and there is
a lot of "fakenews".
Many manufacturers served different markets with different models or
at least used different model names. a highly confusing thing.
Models have been introduced to
markets at different times. Some, say a German customer would only - if at
all - know year of introduction into germany. In some countries e.g. France
not years of make are printed in license papers, but year of first imatriculation.
We actually gave up giving years, knowing this confuses only.
HOWEVER, given the scope of error, a year may help to avoid the worst.
Some manufacturers repeatedly used same model names over spans of, say, 20
years for totally different material. there it helps to have a year
And, to make things worse, it happened that a manufacturer of an ignition
system went out of business, forcing the manufacturer of the engine to
change horses. In such cases it had been some wrestling between the two.
He who was stronger dictated the other what to do. Was the engine maker
the stronger, chances are that the new ignition system would fit as the
one before. If however the engine makes was in a bad position, we might
have had to modify the engine to suit the new ignition. A case for real
problems later on in the bikes life.
This business of replacing old ignitions is at times something like a cross between a puzzle,
detective work and reading tea leaves (sometimes a lot of the later)
