1980 xr200 help/tips
 

Heya folks,thought i'd ask the experts for some help! Just picked up a 1980 xr200,completly standard and little worse for wear!But running. Gonna give it usual clean up,clear out carb fix rear brake(hopefully),mebbe bit o paint. Jus wondering what should a check for on this specific bike,and any tips to improve performance? Also,if anyone knows where to get parts in south island New Zealand? Cheers in advance!
