1200gs with olins from Dan Kyle Racing. Am about to send in the rear shock for a second time. The first time we determined I needed a softer spring. I did not see much if any difference. The spring I have is a 00698-64/160 L476. Searching around I see one rider has a 59/150/257 and another has a 39/110 L213. The problem is almost no sag when riding alone (15mm). The rear wheel tries to come off the ground. Fully loaded is about wright with no pre-load adjustment put in. With suit on I weigh about 210. I need a heads up before I call Dan this time.
