Is there a shortage of K&Ns? Ive got one someone can have for at it cost me. I'm in Praque at the moment so it will have to wait.

In the world of sports mopeds we use k and N's all the time, but often these can have little benefit due to the warm air surrounding the engine being less dense, as picky says.
One easy way round this is to have a large diamter pipe poking out in an open space where air can be forced over the surface of the filter. This ensures you get cold air into the engine, and can slightly improve performance at higher speeds as the air is effectively being "forced" in, not sucked.

Anyone running an mg metro air filter assembly??
I will be fitting one shortly as I have been assured that it fits fine.

No, I'm running with the basic Metro filter which needed the cold air inlet cutting off to fit as it ends up in the battery otherwise. The MG Metro has it on the other side (front for Minor installation) with a length of ducting.
I think I've still got an MG Metro filter if anyone wants it (unless I gave it to Kate). The reason for using the non-MG was that it fitted my HIF38 carb, I don't have the elbow for the MG filter.
I know the theory about inlet temperature (and hence density) but my Minor's always run better on warm days than cold - and yes, I'm pretty sure the thermostat's working.
