I'm trying to get a new to me bike to e-start when hot, and stay running going down the road. I don't need to wait for summer for that. This isn't exactly fine tuning as much as just cleaning and base lining. The fuel screw and jet kit are means to that end.
One possibility i considered last night is I may have just run out of gas, as I switched to reserve after it died on the road lat Sunday to get home. Looking on the tank, my gas level is below the filter of the fuel valve thing- when you switch to reserve, is it just getting gas from further down that pipe? That could mean my total range with the stock tank is about 50 miles- which I'm thinking is pretty poor mileage.
