I just purchased a 1991 Vmax with 19,000 miles on it last Friday. I work on all my own junk so am in the initial phase, on the learning curve, where I am not yet familiar with the bike and its quirks. Bike seems to be running well and the first quirk I looked up was if it was normal for the oil level light to come on when I hammer down. Apparently it is though it still makes me uneasy. Is this forum still fairly active? I was wondering if some of you long time owners could let me know what all is good to look over, freshen up, and change. From what little I know I have changed the fluid in the rear wheel gear drive. I have a fuel filter and air filter ordered. It has a fresh coolant change because the previous owner just finished up changing the starter. The previous owner did do a few ricer things to the bike, like the fake carbon fiber wrap, which I intend on removing. The bike also apparently has the V-boost mod whatever that is called. There is a little three position switch. I'm not sure the difference between the back two positions but the front position definitely opens up the V-boost earlier because at a fixed throttle position I can feel it open up when I flip the switch. Seems like all this mod does is make more power with less throttle input which makes it seem faster though I would think the overall power would be the same as just opening up the throttle more with it off. Any opinions on this? Well I already went on too long so if there is anything I should know or do please let me know.
