Yep, starter motors are another issue on those old Yamaha V twins, as well as the afore mentioned Hitachi carbs, (one downdraft and one sidedraft) and other electrical gremlins, but the engine was a lovely thing, basically two XT/SR500 engines train-smashed into a big V twin.
Giving these bikes away for free must be a common theme world-wide, a mate of mine was given one a year or two ago, he was going to "Cafe" it, he got it running but gave up and bought a Honda VTR1000 instead. Cheers, Terry.
