clutch springs
« on: January 15, 2018, 02:29:09 AM »
I am cleaning and rebuilding the clutch on my 79 Invader, and have two clutch springs, a black one and a yellow one. What is the difference in these, as far as engagement speed, top end speed,etc.

The yellow is stock for Invaders.  The black spring was used in the 80 4/6 LTD and is a little stiffer.  It will result in a slightly higher engagement RPM.  It will also cause your Invader to over-rev unless you add some weights to your ramps.
