Hello again. I want to change the spark plugs and i think of two alternatives: NGK or Denso. Someone told me NGK is not so good for Freewind, that they are good only for injection. Is this true or .. ? What can you tell me ? And second: does "iridium" makes a big difference for a mono ? Thanks again !

Hallo wieder. Ich möchte die Funkenstecker ändern und ich denke an zwei Alternativen: NGK oder Denso. Jemand erklärte mir, daß NGK nicht für Freewind, das so gut ist, das sie nur für Einspritzung gut sind. Ist dieses zutreffende oder. ? Was kannst du erklären mir? Und an zweiter Stelle: „Iridium“ Marken ein grosser Unterschied für ein Mono? Dank wieder!

Look on the page 2 Seite 37.
If Suzuki have no problems with NGK CR 10 E, why have you?
In my Freewind it works very well!

In fact it's a question of belief.
Those iridium-sparkplugs might endure a bit longer than the normal ones.
But in my opinion, the iridiums are only made to earn more money with them.
the iridiums are producing a spark. the normal sparkplugs (NGK or Denso) are producing sparks too.
there is no real difference in the produced spark.
but what i discovered: the denso-sparkplugs have only one mass-contact, the NGKs have two of them. so the NGK produce a horizontal-spark, the Densos a vertical spark.
that's why i prefere the NGK.

Greetz.

It`s ok, thank you. I`ll do some more thinking. In the meanwhile i`ll change the tires: Michelin Anakee ! )
