It would be an option if no other exists, but take it at face value since I am new to this too. I would
assume cylinder 6 would run richer than cylinder 1, because it runs hotter due to its location. More heat = more fuel needed to cool it. However, there are all kinds of other things BMW and VF may have done to make up for the extra heat besides dumping in more fuel to cool it. Maybe the timing is already slightly retarded (but would this throw off the balance of the engine?). I don't know.
The heat shield has a few screws you can take off, then bend the heat shield to suit your needs. The heat shield goes all the way around the headers towards the section 1, wrapping in such a way that I'm not sure removal is practical. I'm just a self-taught DIYer, so what do I know
