This will break your heart Rex, back in 1966 and newly licenced to kill motorbikes by stupidity, my best mate wanted a bike ,any bike but bigger than 250 ,so an outfit was the ideal solution . Igot asked to run him up to formby and money exchanged hands ,can't have been much cos whe didn't have much? Anyway condition of sale was that he tokk "all of the spares " as well .We filled the sidecar with sunbeam bits ,large lumps of engines at least 3 of those massive dynamos etc ,bike duely performed well and after parking up all spares were put in his mums lock upand duly forgotten about ! Bike ran like a clock for a couple of mths ,boredom set in and one on arriving at his house I found him balls deep in the bike ,he'd decided to do a decoke why I'll never know , like a demented dervisher bits were flying ,slight exageration but not by much , all over and after much grunting the head was loose ,he hadn't realised it was ohc so chain still attached another half hour and some how that freed and he was able to clean and grind ,much sweat was created and tempers flared as i was only there watching khaving only just started to dable with my A10,over the whole weekend he laboured and put all together, such requirements as timing forgotten after all he'd not moved the engine (?) moving the outfit about 2 feet in gear hadn't been noticed til later , any way it , of course it wouldn't go ,I towed it ,etc still no life eventually light stopped play ,the outfit stayed there for 2 mths and he sold it for next to nothing .2 yrs later Mums moving and suddenly all these bike bits , she threw the lot in the bin ,what a shame also taught me one undeniable fact "don't try to fix something that isn't broken "
