The point of EFI is that they're not cold blooded. Probably some bad fuel. If the manual says to run regular fuel then 87 is okay. Running 91 or 93 octane won't help the motor run any better. The compression is pretty low on the bike so the higher octane fuels don't matter. Run Techron through the motor once in a while and it'll be okay. As always have fun and keep the rubber side down.
