A buddy of mine told me try out VP ultimate 4 in my bike, if I wanted some more power. Well I gave it a whirl a few weeks ago, and I really liked the power it made. I have read that it would add up to 5hp. Anyhow I ran 5 gallons through my bike and I had recently ran out so I have gone back to pump 93 octane gas, and I'm finding myself missing the power. I wanted to get some of you big motor guys' opinions on this stuff. Now I know this stuff is made for these new 4 strokes and its only 92 octane so its perfect octane rating for our bikes, but I wanted to know if there is anything else I should know about running this stuff. To my knowledge this stuff is oxygenated, and thats why it adds power. Now the power was great with this stuff, throttle response was way up and it reved faster. The only downside to this stuff is that it cost $57 for a 5 gallon jug. Any thougts?
