| Well to a certain extent, getting your weight in the right place is going to help, but it depends on how extreme you have to be in getting your weight forward.
My advice would be to make sure that your tyres are in good nick and correctly inflated, then check that the pre-load, the front and rear ride heights and the compression and rebound damping are set back to standard, then follow through the various suspension set up threads to get the suspension sag adjusted to your weight.
It could be that somebody has dicked around with your bike such that it doesn't want to turn easily, setting everything back to standard will give you a good basis to work from.
If it still feels odd and you really are shifting right forward, I hope I'm not being unkind, but I would suggest that it's probably you rather than the bike and I would invest in a couple of sessions at a school like the CSS |
