well idk if ur talkin to the OP, but for me im getting no codes when i turn the bike on, and i even did the manual plug jump thing and still no codes. im operating at normal temp too.

come to think of it, i do get random codes maybe once every 1000 miles, but either it only flashes a code once to the point of me not being able to read it and it goes kinda fast and is not consistant at all where i can read it again to double check it. and when i tried to get the code from memory there is nothing stored apparently which is why im lost and cant even really diagnose this junk.

Interesting about the high octane. I have been running 87 only because the manual says to. I did thing it was weird for such a powerful bike not to be running 91 octane or greater because both my car and 1900 CC cruiser require it.

Thanks Nikos

I ran a tank of 91 octane fuel and I no longer have black spots of fuel coming out of the exhaust. The manual states 87 is fine but I guess not.
