YFZ masters?

Will a yfz master cylinder work on my blaster or do I need to do some modding?

handlebar mount or rear brake master? the handle bar mount will work with no modding because thats what i run on mine. the rear i think is a little different, the mounting holes are farther apart.
 
i believe that can be made to work, even if ya get the bottom bolt in, and have to drill a new hole thru the bracket for the top, or even a short bracket extension like we did your caliper
 
just make a little bracket and mount it wherever it best fits, should be an easy job. i have no idea which bike mine came off, but i made it work :)
 
Well we did it something new to add to the interchangeable parts list only thing we had to do was put in different bolts with nuts on the ends the master works perfectly.
Btw the yfz was a 2006 balance edition
