Hmm,.... my old 1973 Yamaha XS2 was mebbe the worse.It was the forerunner to the XS650,so it had the flexy frame and the spindly forks.The handling was,....erm,....interesting.
The poor thing had suffered badly from bodging former owners and died on me not long after I bought it.The wiring loom had been hacked into by someone and a crude alarm wired in.All the connections were done with chocolate block connectors,....nice!Took me a weekend of repairing the wiring loom to get it up and running again.
The paintwork was a typical 1970's lurid metalflake nightmare.My mate and I stripped it down to the last nut and bolt and repainted it plain black.I got some good s/h parts from a local breakers and the old **** looked pretty good.My mate also rebuilt the engine top end,so it went pretty good too.
It must have been good as the bloke that bought it gave me almost double what I paid for it.
