You make very good points there,I think you are correct on all accounts ..... I am convinced that my stock Avanti Pacco carb had a marginal sized 52 jet in it when I bought the bike... and that the famed back wheel lockups mostly occur as people come down hills, turning down their throttles,creating heat and soft-siezes... I think Avanti owners should put alittle larger jets in their carbs then the stock ones.. They advertise the bikes for their gas mileage, which is most important to Indian customers due to their econmy and high gas prices, but the engines can overheat.
I'm at work and don't have the manual with me... I'm pretty sure that they said to run 15 miles and let it cool for nornal running, and didn't mean the break in period...but who knows ? The manual isn't too well written...also, maybe they know their jets are small , making the engines run hot , and suggest short hop travelling ? I'll check the manual when at home.
