Sorry for yet another topic on this subject but (I think) I've got a problem with the float height on my '97 900SS. And I can't find the answer anywhere.
I would like to check the actual fuel level inside the carbs (with the carbs mounted on the bike) with the clear-tube-to-drain-pipe method but I can't find what the height is I'm looking for when using this method...
I already know that you have to measure the level to one of the marks on the float bowl but I don't know which mark to use and how many mm I should be above or belong this mark.
I'm talking about the marks in the attached photos. Photos came from this website. Talking about the red and blue arrow. Lots of info about Yamaha there, nothing on Ducati...
Cleaned the carbs, checked everything for leaks and/or wear, set the float heights to 14mm and after re-assembling the vertical cylinder keeps running lean, even with the air-fuel screw 5 turns out. Horizontal is oké @3,5 turns out.
I suspect a problem with the float height on the vertical cylinder carb.
Before pulling the carbs again I would like to check the actual fuel height in the carbs. When I reassembled the carbs everything was checked and all seemed allright. So I think pulling the carbs again won't reveal anything new.
So, does anyone know what line I should be looking at and how many mm the level should be above or below this line?
Thanks!!!
