You might have a point Svtford, it would not hurt anything, the strange thing about this surge is everybodies bike is not surging the same on Ivans flash as we saw in RC's video versus yours, if everbody had the exact same issue i would say yep thats part of it, but your surge seems real excessive. Maybe Avintage will post a cold start on his bike on here or feed us information about the comparison in surging between your bike ,RC,s and his, like which bike his mimics, then that will give us 3 different bikes to look at. Im going to crank my bike today its been setting for a week and see how it acts.Taking a shot in the dark here. If it was actually due to timing is it possible to pull timing while it's warming up? It sounds like an iacv surge like the old Civics used to have. Maybe there's an idle relearn procedure? Wouldn't hurt to disconnect the battery and see what happens.
