I came across this macbor xc-515r 6 speed dirt bike in pretty good shape.payed 150 bucks for it not even sure thats a good deal or not. But I seen the 6 speed trans n I couldn´t help myself lol... seems like its all there except the carb. I can´t find one anywhere is there one that will fit n do the same job? Also is there a wiring diagram anywhere for this thing........
