Agree......not a complicated job to mend it yourself, if you've got the manual for it.I reckon fastbob's right - it will probably be something to do with the selector mechanism. Only thing to watch is if you can't get new parts, be very wary about buying 2nd hand stuff sight unseen. I has an XS750 2D that ate it's selector drum and almost every drum that I found in various breakers had the same pattern of wear. Eventually found a replacement in Southwark, of all places, fitted it and all,was well again. I think that's why the 750 2D was eventually replaced by the XS850, but there were never as many of them about as the 750s. 9mnths on he may have fixed it ....
