My front forks seem to be sagging a bit too much (around 8cm!) without me even on the bike. The Hornet 600 doesn't have any adjustments for the forks. I went to my local bike mechanic and he advised me that I can put a couple of washers/ spacers above the spring, to increase the preload and increase the fork oil weight to slow it down. He quoted me around $130 including fork oil. Is the above practice a dangerous shortcut, or will it work fine? I do not and will not ever race, I just want a stiffer front end, as it seems to almost bottom out under brakes and some bumps. Thanks in advance for your opinions. Daz.
