Bike wobble out of corners/with speed

[papercutout]

I've had this for a while now, but finally decided I need to get it sorted! If I hit a bump mid corner, the bike gets a lovely (read; scary) wobble on when travelling at a reasonable speed. Even worse is that if you get to around 100 leptons and are accelerating but not gripping the tank hard with your leg, it also gets a big wobble.


I've just had the front wheel rebalanced, and that hasn't helped. A little while ago I changed swingarm and fitting new bearings, that didn't fix it (but my new swingarm is powdercoated black, so that's a plus!)




Has anyone got any suggestions? I only weigh 60kg's and it's better with more weight, but my old one didn't do it.
Thanks
