I also wanted to add a bit of info that I got from progressive suspension in regard to the PCS spring if someone decides to install it on their 465.
Even though the 1181-20b spring is 1 inch longer than the spring that comes with the 465 shock, the "minimum installed length"
for the roadstar bike is 142mm (5.59"
and stays the same with the new 1181-20b spring.
When you remove the spring from the 465 shock there will be two clip grooves showing. Put the clip back into the original groove it came out of. Do not move the clip to the top groove.
