Hi, I have an 81 750 special with an engine that was partially stripped 4 years ago. Since stripping it I have moved about 6 times and have now lost the cams and a few other very top end bits. My question is this. Where can I get parts for it? I've tried eblag etc but am unable to locate them. I'm running at a loss now and am looking to have to buy a new motor. If it gets to that stage, will a 94 motor fit? What will I need to change? I'm sure there's something to do with the electrics that needed changing. Gotta re-wire it anyway so hoping it won't be too big a problem but would rather keep the original motor.
