Hi mate, thanks. I found left exhaust and intake were out of specs by very small margin. It was only difficult due to the range is starts from very close to zero thus makes use of my smallest feeler gauges which was kinda hard to put through and also the space on the bike doesn't help. All in all wasn't very difficult though had to removed what seemed a million bolts to get there, using several different sizes ... other than that wasn't too bad. Finally got it adjusted on a proper shop as I was running out of time, basically cause I didn't have the shims to replace it I followed instructions http://faq.f650.com/GSFAQs/Valve_Shim_Change_FAQ_GS.htm obviously disassembly is different but checking is very similar. Picture wise, didn't manage to get something useful and detailed enough to my liking, but go some 1. Airbox removed, including 2 zipties, bleeding hose, butterfly, etc 2. another look to the intake duct that is bit dirty 3. Front bolts are difficult to access due to angle Finally the inner spark plug was hard to remove, due to again space and angle Hope this helps, what do you ride?
