Guys, I'm wondering if anyone has a link to the standard jet sizing and numbers for the Dell'Orto DHLA's.
Thanks!

I check all the jet sizes because the little GTV seems to run very rich, to the point where it stains the driveway with black soot everytime I flash her up.
All the jets are standard, so I'll have to investigate further...
