That sound?

A new sound from the octane

That almost sounds like the Electronic Throttle Body. I've been noticing mine do that, but I doesn't for that long unless I'm riding it.

It is the fuel vent. When it's hot the fuel vents and it makes that noise. There is a fix for it on the forum www.thevog.net under the forum, octane section. Just did the fix on mine yesterday and so far no noise.
