Ok, here goes, decided a couple of quid may be worth spending (whether I have it or not!) and Skids reckons he can sort a spacer to fit old spindle and forks 

 (as does Nick B) 
 light weight wheels
 ally swingarm 
 condition and looks not too worried about, just needs to be usable without any additional work 
 got to be worth at least 2 seconds a lap 
 
  also looking for an ally engine bolt kit if anyone has good (cheap) source 
 any other quick easy changes??
