BP with Invigorate = Lousy Running Blur

[HanShan]

It's official, after my testing my Blur on an off BP gas with Invigorate I can say for certainty that it runs much worse on that gas. The gas makes my idle rough and the bike vibrate much more through all RPMs.

Exxon gas works great.

Car manufacturers will sometimes do all the pre-production engine testing on a single brand of gasoline. It eliminates one variable, like fuel quality. It also means that production engine will run best on the brand of fuel used during testing.
Its possible that Genuine/PGO did their engine testing on a single brand of fuel.
