MR9 -U2 OR U4?
Have read in a lot of places that MR9 fuel would give the best HP; in this case for my ZX-10R.
Person selling the fuels from VP1 says I will probably get as much power out of U2 or U4 and pay a lot less as MR9 is more expensive.
Any thoughts on experiences here in the forum on these fuels?
MR9 $119.00 For a five gallon quantity
U2 or U4 $71.65 for 5 gallons...
He figures that the only reason pros advocate or recomend MR9 is because it is AMA legal fuel where U2 or U4 is not? I just want more power and a smart buy; I think MR9 is what I want cause I did not think it would be close to anything else out there for producing power.
Am I right?
Thanks!

Ryan Schnitz told me me mr9 will give you a couple percent more over u4, he said u4 will give you 4to 6% more, i use u4, but i dont have to pay for it either......
it is the best bang for your buck, and you dont have to drain the tank like you do with mr9. Just dont leave it in there for a month at a time without running the bike, a week or two is okay. make a pass on pump, then drain all of it, and put in u4, you will never run pump gas again after you see the mph and back half you gain with it.
if someone is really kicking your ass mph wise, and you dont know why, they are using it.

make sure the cats are removed before you run U4 or U2- they're leaded!
