Further to the two points in Mx{John H Maddocks - Chief Proving Officer}7/T9.4.35 - the Experimental Dept. recommend that the Side Steering Tube poundage should be reduced from 5 lbs to 2 lbs. To obtain the reduced poundage it is necessary to delete the Washer G53R71 and reduce the Spring G53163 .050 in length. This applies to the front end of the side steering tube - the rear end of the side steering tube is unaltered. | ||
