If it lets more air in then surely the air/fuel mix ratio will be out and so I'm not getting why foccers above feel that no further mod is needed; unless of course the bike runs slightly rich in the first place - but mine doesnt - and the plug electrodes are a white tan colour which indicated to me that I would not want to go any further with in terms of letting more air in as I suspect the plugs would overheat.
We can't all be wrong?

I'm not disputing that, but rather trying to understand the logic here, which tells you that if you put more air in then the bike runs leaner; which is not what all of you are saying, which is why I dont understand. ?? unless the bike is running slightly rich to start with - as some indeed do
