I would think that Tnpshow is on the right track here (pardon the pun)

Sounds like an alignment issue to me

Yeah thats wat i thought .na havnt had an allignment. got an engineer looking over it this saturday so hopefully it gets passed and then i can get it reg and can get someone to have a look at it. It feels more like the the turning circle has been altererd by the conversion.

I wouldn't have thought 50mm would make that much difference.

Have you had a wheel alignment lately?

Hey need a bit of help with the stearing in my 1000 the front feels alot heavier and the handling isnt as good than the last one had i think its cause the wheel track has been widened by about 50mm caused by disk brake conversion. would that make the difference?
