My 01 superhawk seems to only like fresh fuel from the pump. Even 1 day old fuel seems to perform less than optimum like freshly pumped fuel does. Does the fuel degrade just enough in that 1 day or might something be off in the superhawk?

 

Some days mine runs great, some days things just don't "feel right". It's NOT the bike, it's me. Maybe that's your fuel issue?
I do know for sure that running third rate fuel for the long term will cause issues. In some of the vehicles I've owned I could tell a difference in how the motor ran right after a fill up with other than my usual gas.
Just some food for thought.

 

You need to keep your fuel refrigerated @ a cool 53 degrees It's cooler when it comes outta the underground pump, hence your slight increase in performance.

 

Here lies the key word. The gas is not your problem.

 

It seems like the gas. It may be some system on the bike. The hawk accelerates better with fresh fuel than with a couple day old fuel. Fresh fuel performs noticeably better than fuel that has been in the tank a couple days.

 

Well, if you're so sure it's the gas, then something may be contaminating your gas. Perhaps run a fuel friendly cleaning agent like seafoam or something like that in your gas tank.

I doubt this will solve your issue, however, it will help eliminate potential contaminates in the fuel distribution system.

 

This bike has been like this since I got it. But was in **** poor shape when I did. When I first changed the clutch fluid it changed the friction zone on the lever it was that bad. But I have added inline fuel filters and I would put in sea foam or Royal purple with every fill up. But after a day or so it would return to its normal state when I would like to figure out how to keep the power it gets with fresh fuel.

 

Hopefully my winter maintenance may fix the issue. Plan to look at the CCT, valve clearances and do a good carb clean/sync. Has roughly 40k miles

 

It's not the gas.

Any thoughts to the issue then if it's not the gas?
