hello mate - yes I did change the tyres, and that sorted the problem I was having at the time, so I was well pleased with that

.
My problem now is that if i ride around pretty gently the bike feels ok - its stable and rides pretty well over bumps, however as soon as I start to up the pace even slightly the handling goes to s**t! I have changed the suspension settings to those reccomended by PB magazine and that improved things, it really firmed up the front end nicely, but it still feels like the rear end sits too low, especially when going around a corner, when it kinda feels like I have no weight over the front end. If I really push my whole body as forward as possible and try to lean on the front end it feels a little better, so I suspect my rear end is squatting down too much, making my bike ride like a chopper!?
