If you are detonating a stock bike, unless you are a intermediate or pro racer, fix it for cheaper.
And what it takes to fix it isnt going to make a slow rider any slower.
But hey, 33 bucks for practice racers keeps race fuel peeps happy and their Lambo payments paid.
Oxygen, Energy, Comtrolled burn...things like that.
That's why I run and tune with good fuel.
I run VP T4 in my off-road bikes and U4.4 in my MX bikes (all 4T).
My old RC250 2T runs on VP that's already premixed at 50:1.
Does race gas cost more? Sure.
I'm worth it.

Yes E85 works great in engines build specifically for it, Ive got a LS1 Camaro that I have thought about switching but just can't do it because we don't have E85 in my area. For my bikes I just want the best possible. Good fuel in a 2 stroke with a short silencer should make for a fun day at the track!
I want to run race gas just so I can smell the fumes...Mmmmmmm
Most people don’t have problems they just want to be in the cool kid club. The fact is, that a stock engine running on VP is an astronomical waste of money with 0 benefit
What is cam2??
Re-branded Sunoco Race Fuel. Not sure if it is around anymore, this thread is 8 years old.
Consistency is one major benefit
I've found CK91 rips pretty good in 4-strokes.
Sunoco. Just like Trick was a Phillips 66 product.
Since this thread got brought back from the dead. What fuel yields the most HP gain in a modern, unmodified 4 stroke?? It’s for my snow bike at elevation so yes the HP gain actually does matter.
Half clear 93 and half VP110 with Maxima oil. Smells like nostalgia and rips
It’s pricy but MR12 or MR- Pro6 will make the most power but it’s about $160-200 for a 5 gallon pail. If it’s a two stroke then MRX02 makes the most power.
Pit Row
One of the big differences is VPR is leaded and T4 is unleaded. Injectors are designed for unleaded fuel, have no idea if unleaded is a problem for them. Can't remember if the 09 CRF is carbed or not but I think that was the first year of EFI. I sell T4 like 4 to 1 over VPR.
This is something I’ve been curious about. Does running 110 in a modded two stroke actually add power? Or is it just needed for the higher compression? The only reason I ask is because the last 6 months I’ve been spending the extra money on u4.4 because it legitimately adds noticeable power. Even to a stock engine. Prices are insane now, 110 is around $80, c12 $90-100, and u4.4 $110-130.
VP 110 doesn't add power to a modded 2-stroke but it is a good safe fuel for compression and timing also really cheap out of the pump here in SoCal little over 8 bucks a gallon at Downs fuel
Still $8 after the last 6 months? I’m an 1.5 hours from there but that’s worth the drive. Indio had Sunoco 110 for $10 at the pump, but now it’s $15
AV gas and a turbo is far more effective and cheaper overall. 1
Honestly I just don’t trust aftermarket kits. I’ve yet to see something with forced induction that wasn’t factory run reliably. Yes they run like a raped ape, but for how long? I’ll take reliable N/A power in the mountains any day.
Turbo k series engines are capable of a reliable 400whp on a 100% stock engine. I remember a guy had a f series with a head gasket making 700whp, he had a built block in his garage on stand by, and I believe sold/wrecked the car before he ever needed it. It’s all in the tune as far as those engines go
I’m talking about dirtbike engines. The kind where when they break down it’s a helicopter ride out of the mountains. If it could be done reliably there would be bolt on kits available. The snow bike crowd isn’t afraid to spend money on power, but it has to be reliable.
Ahh that makes sense
Yes $8.60 a gallon but they only have it down at Corona Temecula doesn't sell it anymore that was a month and a half ago
One thing about pump fuel even race fuel at the pump is it’s vented. It heats up and cools down and vents and also allows moisture and other contaminates in the tank and isn’t as consistent as a sealed pail or drum of race fuel. When I was younger I used to get 110 at the pump and it was never consistent. Keeping your fuel sealed and fresh is key.
