Dell’Orto carburetors - Slide needle specifications

Jens Lyck's Guzzitech.dk website archive is now hosted on This Old Tractor

Jens no longer owns a Moto Guzzi and has turned his attention toward his new motorcycle. Rather than let his wonderful online resource fade into oblivion, he has asked me to host his content (both the Danish and English versions). I am proud to do so. I have referenced his excellent compilation for years doing my own work and will continue to do so.
