I think jay was sounding a welcome note of caution for folks like me with, as he knows only too well :) , very limited ability in this case it would be made worse by the close proximity of the winsford contingent and their talent for burning things down ;)

For the avoidance of doubt and for the benefit of my wife, not everything I may say here will be absolutely true I may on ocassion embellish a little for effect.
That said when it comes to motorbikes, I like to ride side saddle with a nice frock

If you're unsure about using a naked flame on aluminium, use a heat gun. You can get them for about £20 from B&Q etc. They're also handy for shrink wrapping wires and stripping paint off door frames without scorching the wood. 
Anyway. Since a press has been mentioned, I would certainly not recommend going in 'cold' when trying to press a bearing out (or in for that matter). Aluminium (whatever the grade) is a bitch of a material to work with. It cracks, it sticks, it bends, it melts.. All without much effort when worked incorrectly. The ideal way to remove a stuck bearing would be to apply a penetrating fluid over the course of a week or so. Diesel is a good shout, although I prefer to use Plus-Gas or GT-85. Apply some heat around the area to expand the ally, but trying not to heat the bearing directly.. It's the ally you want to expand. Depending on how the bearing is to be extracted, either use a press or slide hammer.
Like with everything, it's easy when you know how. The beauty of forums such as this is the vast range of practical experience when it comes to this sort of thing. One mans method won't work for another, and as you're having a go, you may find a way that no one else has thought of.

Most motorcycle problems are caused by the nut that connects the handle bars to the saddle.
