I have an 82 Sabre V45 750 that has given m fits for the last 3 years for one reason or another. Right now, it´s a frozen choke. I don´t want to force it too much and break it. Another issue I have is restarting when the bike is warm. Even after 4 miles to the gas station, I have to let it cool before it will start again. Frustrating, to sat the least! I have a good mechanic. Fluids are full and I installed a new radiator cap.
