Scooterotica

what cdi are you using?ducati or pattern?

Champion in it at the moment. 50 miles home from the Ace cafe and caning it all the way. Ran sweet as a nut. However plug very oily upon inspection the next day. Not started it since.
Ducatti cdi fitted, 800 miles ago.

should be fine then...as ive said i had a similar prob..it was eating plugs,when i got the scoot dynoed at readspead i mentioned it to jerome,he basicaly once the plug gets "wet" the spark will arc to its most direct route,im running an augusto myself with a pattern cdi and not got any probs as yet but ive a ducati one as back up.a 9 plug is for total balls out as you know,but round town it could be fouling up,id seriously try an 8,anybody any thoughts on this?

i agree........an 8 would seem a better bet..........and more suited.

The champion i've put in is a 3, equivalent to ngk 8. Will have to see how it goes. Must admit, the 9's seem to be failing after running around town, and I was in heavy stop start traffic on sunday when the 9 packed up.
I just want to be a bit more confident before riding to Scarborough next week!

my own thoughts are champion for standard engines no problem ,ngk i didnt have problems with 20 years ago on tuned engine however lately cant get on with them currently running nippon densos . not had a problem as yet .it is correct in saying the 9 is no good unless youre caning a really fast motor .interesting about the wet plug arc thing though .

oh and agusto fitted ducatti cdi .

Regarding the Nippon Denso,s if i remember rightly its a 24 for normal rideing and a 27 for the faster long range trips, if ive got that wrong could someone put me right, Ta.

no youre spot on mate its ngk rating x3 for nippon .

Just an update for interested parties.
Have had champion N3 in scooter for 600 miles now with no problems. Thrown the spare NGK's in bin!
