Interesting one this. Customer bought this L reg 1972 Yamaha XS650 off Ebay, was running but filled the road with smoke - looked like the workshop was on fire again! The frame was chopped in the 1970s. Plan for this is a general tidy up, custom banana seat, rebuild the engine with a big bore (750cc) kit, RamAir filters and Mikuni Smooth Bore carbs. I'll let the customer ride it - he'll probably want to sort the suspension and brakes then!
