Couldn't believe my eyes when I came upon your remarkable website. I had no idea there were so many knowledgeable and enthusiastic Dell'Orto fans in one place. For the most part dellortos are not that popular on Harleys in the United States any more, perhaps they're too much of a challenge for most to tune. Admittedly, I had major problems for several years trying to use harley's traditional gravity fuel flow. From a full tank to a half tank or every 10 degrees change in temperature required an idle mixture screw adjustment. Finally, the very good people at Dellorto.uk put me on to the dellorto vacuum, pulse pumps and provided excellent advise and parts. Since that time I've had very satisfactory results. I've also used many of the tuning books, including Jack Wagner's book on tuning dellortos for harleys.
My question: since I'm always trying to learn and considering the topic of my post may not be appropriate to your website, are you able to direct me to a comparable site or source that is? Thank you very much.
