Hi. I own an unmodified 1983 MkIII Le Mans (UK registered) and am overhauling the carbs (Dell'Orto PHF 36). I see that there's a big difference in the UK- and US-jetting that was used for this model: main jet 132 (USA 115) idle jet 60 (50 USA). Can anyone help with the following questions, please?
1. Why does the US-spec bike use smaller jets (for emissions maybe?)
2. What jetting actually gives the best performance for this bike?
3. Is the standard 265AB atomiser best for the bike, with the K18 needle on third notch?
Thanks in anticipation,
Craig
