MotorHoss: Harley Davidson 88 Twin Cam Hot Start problem.

This hot start problem got old very quick. It is not the final option, but it is nice to have it start when hot like it should. I adjusted the float as per spec, 15-20 degree angle. removed all jets and orifice tubes, cleaned out everything. I believe that when you park and have the kickstand down, as the fuel boils the bike leans to the left resulting in the boiling fuel to run into the intake and flood. Just a theory. This section is from the Military Trader website: Fuels sold in the winter are blended to have a higher RVP than those in the summer to aid in starting. By increasing the RVP, they lower the boiling point and increase its volatility so it takes less to turn it into vapor and hence start in the cold. In the summer, the warm temperatures are already assisting in the vaporization process so the gas itself doesn’t need to be as volatile. Winter: High RVP = Lower Boiling Point = Faster Vaporization Summer: Low RVP = Higher Boiling Point = Slower Vaporization Raising the winter RVP is usually done with the addition of butane that is very volatile (high RVP) and inexpensive. The highest RVP gasoline commonly sold will have an RVP of around 15.0psi (measured at 100 degrees F). If that gas were in your tank on a hot summer day when the temperature reaches 100 degrees, it will boil in the tank. On a 70 degree day, the heat in the engine compartment will reach well over 100 degrees, especially in a parade or at rest. Vapor lock often occurs when you first stop...
