I installed progressive fork springs tonight after work. Wow what a difference. I should have done this a long time ago. I read on this site that this is one of the best improvements you can do to the VN 750 and let me tell you it’s true! Anyone that is hesitating doing this don’t it is worth every dime and the time invested. It was too late to get fork oil at any of the local bike dealers, and when I pulled out my springs the oil looked and smelled bad so I got some Amsol synthetic universal ATF at the auto parts store. I figured it’s got to be better then what was in the fork tubes. I changed the springs by putting the bike on the center stand and a floor jack under my engine guard. So after taking out the springs and draining the oil I just lowered the floor jack to compress the fork tubes into the sliders to remove all the oil and to get the proper measurement of the new oil. I cut my old spacers and put it all back together. This is an easy project that can be done with the simplest of tools. I highly suggest this upgrade to everyone with this bike.
