The sprag clutch assy is located in the primary sprocket on the drive side of the crankcase. This part provides better inflexibility of the sprag mechanism during initial cranking. The auto decompressor device further helps in plummeting the load on the sprag clutch assy during preliminary cranking and also prevents the reversal occurrence of the crankshaft
