OEM BMW springs use 13 coils of 0.032” [.81mm] wire. These springs use 12 coils of 0.037” [0.93mm]. The pull (tension) of OEM springs is 2.5# [1.13kg] @ 0.25” [6.35mm]. The measured pull (tension) of these springs is nearly 5.0# [2.27kg] @ 0.25” [6.35mm]. DOUBLE the tension. I installed them but immediately removed them; too stiff for me. I will order the ‘Quick Twist’ springs (p/n:1311125), perhaps they are closer to OEM springs. $10.95 not worth ‘returning’ due to shipping costs. :(

My throttles would not close completely to idle unless I rolled the throttle all the way back. Swapped the springs out and it corrected the problem. Easy to replace as you do not have to remove the throttle or choke cable. You do have to dismount the carb from the boots. Check the repair manual to make sure you have the correct orientation.
