XT250 manual 1980! Hello Davoz73, I also just bought a xt250 from 1980. It starts real easy, but has problems with idling and it doesn't feel smooth when you go through the rpm's. I have the idea that it blows back into the carb, and that the mixture is lean.. Ok, I have quite some experience with motorbikes and I have ordered a stroboscoop for timing adjustment, but I am loooking for a xt250 1980 manual downloadable, so I know the details of the bike,
