RPM's will be 1800-2100 for cruising at 65-75 in OD. Direct will be 2400-2800 for the same speeds. Definitely will be heating the carb. Check on the VAC-ADV, Carb lean cruise mixture, and 195 thermostat. The warmer thermostat also allows more heat from the heater in the cold months, so it's a win-win for comfort and better combustion. smile

Thanks Panic, I will implement these as I get mine pieced together and back in operation.
