All I did tonight was remove the tank, panels and seat, and then removed the second-hand carbs I got from eBay. They hadn't cured the problem, so I might as well put the refurbished ones back on. With the tank off, I decided to remove the rocker cover and check those valve settings for the 100th time (just to be sure). They were all spot on!
Whilst removing the carbs (jeez - what a tough job), I realised just how hard those rubber inlet stubs had become. I'm gonna have to replace them with £15 replacements from DS. Just ordered them.
