My bike just doesn't have the same punch it used to. Definitely down a significant amount of power. Both the uptake and top speed are significantly lower than they used to be. I think it's after a bad tank of gas. Had to tank up in the middle of nowhere with low octane, and since then it just hasn't been the same, even though I've since tanked up a few times with higher octane gas. It's due for its 2nd service, but I'm wondering if this is something I can maybe fix with a fuel injector cleaner additive to the gas? Anyone experience this?
