Dellorto main jet sizes

Hi all. I’m new to this, but would be very grateful for some help. I have a 350 ducati engine (from an alazzurra) and want to lose the standard filter and replace with K&N style filters. The carb is a PHBH28) What Jet size would you recommend?? (And where to get them from?) Thanks!

You can get jets for del orto carbs from gutsibits.

I’ve only just seen this but if you haven’t resolved the issue then try Eurocarb LTD. (0118 984 2811) in Reading for advice and parts. Good luck.

Southern Carburettors in Crawley (West Sussex) are amazing when it comes to anything carbs.

Thanks that’s not far from me I’ll get on to them :blush:
