It seems like from 14 mm and larger seem to fit, but luckily some of you have not stripped the filter yet? I would really want to know which it is before jacking it up.
I think I will call Ducati service to see what they say.
The mesh screen seems to be bigger than 14mm. The side plug is 14mm but the plastic screen is bigger I think. I tried 14 on it and it was too small.
sorry, you're right. the later 4v models have the all plastic screen. pretty sure it's 17. not sure that i'd try to put 10nm on it. doesn't the blanking plug have a form on it to hold the screen in? i forget now, haven't had many of them apart.
