I am interested to know the answer as well, also I am hearing different opinions on weather you need to remap to run mr12 or not. have you tried the mr12 before?

I have not so far just the t4e I talked to a vp rep and he says that regular u4.4 is now available to ny so I called my local dealer and he said he is going to be calling his rep to make an order for me and I told him to call me before he orders u4e and if he can get u4.4 to just order me 2 pales

Do you notice any power increase over standard fuel?

I believe U4e is for higher compression engine than the other.

I run t4 on my stock kx450

Have you or anyone ever put a bike away over the winter with vp in it? Do you have to drain the vp out of the bike and the efi system? Or could I just switch back to pump gas for a tank or two and store it with that in it

I've never had their fuel go bad!

U4e 113 octane is for modified higher compression than stock, is what I'm reading

The U4.4 fuel won't pass AMA testing if your racing where they test fuels after races

I've been talking with the VP guys often and T4E doesn't contain ethinol. They are going to replace the current T4 with this new formula. The new T4E is a better fuel that my engine builder (Twisted devolpment) and VP reccomends using over standard T4.

I've burned 10 gallons of T4E and works great. Do I feel a difference over normal T4...Not sure, but they will be the same price just a new better formula. Hopefully this info helps!

U4.4 made mine run like crap.

MS103 or the 110 works well with no remap.

Not sure on the T4 or T4e but would like to know.

Keefer said the T4e was a good fuel.

What do you ride ? Stock motors ?

Really any hint as too what's new or better? And are you're motors stock or high comp or what

I put full tank in my 450. Heck ya there was more power. Next tank I had to pay. Back to pump gas for me.

My 250f has a high comp piston.

But T4E and T4 are made for direct pump replacement without needed remap. It's the least expensive pump replacement fuel I think from VP.

It's odd that they use the e nomenclature to indicate they are using ethanol instead of MTBE., but now there is a new fuel with the e suffix that doesn't use ethanol????

U4.4 is for modified higher compression motors. High octane would burn to cold and slow for a stock motor.

Right from the VP Website:
"With its higher octane rating, U4.4 is designed for use in stock and modified 2-stroke and 4-stroke applications"

I use U4.4 in my stock with pipe KX250F, CRF250, and have friends that use it in YZ250F with no issues yet.

T4E is Ethanol.
Just like any other of VP's E fuel unless they changed their labeling, but all the other E fuels were Ethanol. Like U4 and U4E.

It's hard to find non ethanol in some states where MTBE is banned. Pretty soon it will be banned totally because retailers are supposed to verify it is used for racing only.
NOT Recreational off road. SO to avoid getting fined, they simply sell legal fuel.

Oops sorry I was thinking that was the 113.

It does say it requires changes tho, as in it's not a direct replacement for pump fuel which may be why it didn't work for you?

I'm just relaying what was told to me. I have no proof one way or another.

C-Joe nailed it.

I've seen T4 poured into bikes at Factory Demos & a few shootouts.

T4/T4E gives EXCELLENT throttle response, consistent chemistry and oxygen levels (ox and some chemical levels at the pump aren't always consistent).

Sometimes when I want more energy (especially more Ox) I add 1 gallon of U4 to 2 or 3 gallons of T4 (2:1 - 3:1). On "lean" bikes I've gone as little as 4:1-5:1. Note: more Oxygen can often make the bike run a little bit leaner...or at-least give the same affect.

My injeceted Bikes seem to really like T4/U4 at 3:1. They run noticeably better and often have "snappier" throttle response. On the RMZ I run 4:1.

Good Luck!

I ripped a start from Egypt and I was happy about that.

You can try to get VPR too, it's cheaper than U4.4. I ran through 10 gals of that stuff, makes great power. Went back to 100 pump last week and my one son was having trouble clearing some jumps. Topped him off with U4.4 and all was fixed! I will be going back to VPR. (2strokes)
Oh, my brother leaves U4.4 in his carb all the time, even through the winter sitting.

VP makes a premix called T2. The stuff is excellent.

Has anybody used VPR? Buddy has a can and was thinking of trying it in my 16 CRF250R. No motor mods only FMF pipe and silencer.

VPR is a replacement for regular pump gas. it offers better throttle response and slightly more power but the main thing is it's the same fuel every time. we have been running it for a couple years and have had great luck with it.

Thanks. Think I may try a tank full this weekend.

Never had a problem with it in my Yamaha. But the Husky doesn't like it for some reason.

T4e is what ill be running.

Anyone try the MS103??

Can I run T4/T4E straight on the 350??

The u4.4 helped out my 250 with throttle response a lot and I'm looking for that on the 350 as well.
