VP fuel question

I know that at least Rob and maybe a few more guys around here are running VP in their bikes.
I'd like to try it out at the track.
What particular fuel do you use and where can I get it? Price?

I ran VP U4 in my racebikes. Loved it. But you wont get the full potentoal unless you get your bikes dynoed for it. Where in Chicago do you live. I know alot of places that stock it.

Instead of VP, I chose to run Rtech this year. It is working for me. Kevin Hanson at Safety First sells it.

Dongie, Just watch out with that stuff i ran it on my drz and i let it sit in it too long and it ate away the float pusher and my fuel petcock diaphragm on my DRZ. If you get it mix it 50/50.

If you run the new stuff that VP repalced the U4 with you should be fine. But yes the old VP U4 has to be drained after you use it. I don't know if CCC or Champion carries VP. I do know DGY and Prosource do but thats a haul for you. Maybe give 4&6 a call.

U4, now i run the Sunoco race fuel, they sell it by my house in crystal lake at the mobil station, i mix it 50/50, i also add some lead additive, its supposed to help the intake valves.

Heres a link to local stations, it looks like Bensenville is the closest to you, just go out Irving park rd, its by the airport. The sunoco fuel is oxygenated also 100 octane, I havent had any problems with it. just get a couple 5 gal cans worth and then mix it you can go down to 30/70 - 30% race to 70% 93 octane, that should be fine.

I haven't run U4 in while. It will gum your shit up if you leave it in for any significant amount of time, and you need to be jetted properly for it see any worthwhile gain.

Cheapest I've seen it is $70/5 gallons from Lithium Motorsports. Might have been a sale, I don't know what it'd be now.

FWIW, I don't really think the few extra HP is worth the cost for Race gas on Sumo bike.

Well in that case let it rip. It smells awesome and you might be able to tell on the butt dyno. 5 gallons in not going to hurt but just make sure you use alll of whats in you tank before the day ends at the track and you run a mile or 2 with regular gas once done with the VP

Just pick up some gt260 sunoco, out here its like 6-7$ gal, no gumming and a little more preformance, it runns cleaner. Rob is right about running U4 if you are not jetted right its not worth it.

yeah. especially considering that I'm so slow and should rather work on my riding skills than worry about extra hp
I think those 40-45 horses my DRZ is sporting now is plenty enough for my skill level.

Also once you run the VP you wil not get the smell out of the tank no matter what you do. I topped of my CRF one time with it and the smell never went away. hahaha

After the flat track nationals last weekend, I've been having vivid dreams backed with the VP fuel smell

I give VP U4 out as gifts to my girlfreinds. They sell them in little purfume bottles.

Wait, you don't just pour the VP or Sunoco straight in your tank?

Yes, you can run it that way, I just mix it to make it last longer and unless your running a real high compression you dont need to run it straight.
