I've got about 1,000 miles on my 2015 and thinking the springs should be run in by now. Tried to set my sag and the front is adjusted all the way out and I'm measuring 8mm using the method in the manual. The manual is calling for 10-15mm. I'm thinking i need lighter for springs. Can someone point me in the right direction? I want to make sure I get the correct spring. Has anyone changed these out? Is this something I should have done or can a reasonably well mechanically inclined person install them? Also I'm wondering if I could get away with just replacing the spring in the right leg? Seems reasonable and would be 1/2 the cost and effort.
