My sons stock 15 r3 other than yosi Exhaust. Had bike 3 years and find front end really soft. Can we just change to stiffer fork springs like .80. How hard is it to change springs? Is it just take caps off and change springs with weight off forks. Not looking for any thing for track use just more rider friendly. Sons weight 175 pounds I weigh 195 pounds and like to take r3 for rip once and awhile also. But bike has just way to much fork dive. Any springs work better than others. Not wanting to spend crazy amount on upgrade. Thanks for any help.
