Welcome nirrot" yeh its a task of patience, you have to ask yourself, how far do i go,,, is it ridable / show standard or what,
coz ther a lot of money to be thrown at a project,,, and if its profit your after, the XS250 wasnt desirable in the1970"s , so can"t see that changing now,, great experience tho, the reward is getting it up and running ,,and riding down the sunny lanes ,
