KTM rider's pamphlet dated January 1978. Covers GS and MC bikes from 125 to 400cc. These came with the bikes back in the day. Includes extremely valuable information with sections on technical data, tightening torques, gasket thicknesses, tolerances and clearances, oil quantities, gear ratios and top speed, basic carb setup (jetting) and more. Well read and somewhat frayed, but still very readable. Pictures available. $25.00
