Hey guys I got a question about the vboost. I just got a 89 vmax and there is a toggle switch on the left front side of the bike that the previous owner said changes the RPM vboost comes on at. I think it's a mod but not sure. I have no experience with vboost but I can't tell a difference no matter if the switch is up or down. Is the vboost a noticeable difference in power when it comes on? How do I tell if it is working? The solenoids are making a noise when the key is turned on so they should be working. I'm new to this so any help would be great thanks.
