being looking at my minors hubs and have noticed that the castings seem to have a wieght built into the design offset.
best way to describe it is take a nice machined hub and add metal balance wieght to the hub<br>

whoops added a picture,
"And you want to.....?", know if they are all like this or wether to have the hub machined to balance it better

If you mean that the machining seems to be offcentre, then yes it often is.This used to worry me as it looks quite thin in places, but as far as balance is concerned, if indeed that does concern you, then I would say it is not of sufficient diameter to worry. If it was for land speed records etc, then of course it would be in the bin along with a lot of other badly machined bits on the minor.

thanks les thats what i mean't, i have the drums off at the moment and i was checking the bearing and notied it stopping in the same position after spinning.

Yes, I suppose it would tend to make the heavy side stop at the bottom, although being near the centre of the revolving wheel, I imagine that the imbalance is small, but as I hinted earlier, it's annoying and shouldn't be like it. There are places that balance wheels on the hubs which presumably takes these discrepancys into account.

The drums aren't balanced either -so if you are on drums - you can set the adjustment hole along with your perceived 'heavy' part of the hub! But it's all at such a small radius that the overall effect is v small. The front wheels are easily balanced at home - just back off the shoes or remove the pads if discs - then allow the wheel to settle. Add weights opposite the heavy section - until it settles anywhere. This is just a 'static' balance - but i've found it perfectly ok for any sane road use!
You should of course mark wheel and drum - so you can refit the wheel in the same place next time it's off - or do the balance all over again.

They also used to cost about 3 X Minor cost!
