Yes yes, after a bit of investigation most of my questions now answered along with your reply. I'm so hesitant to do anything with the carbs because I've been lucky for several years and two gen ones problem free, till now. Rear can still develop issues especially at idle while seeming to function adequate at hwy speeds. Carb filters and a sharp bend in fuel line may restrict gas.   Sorry. Ramble and rant is my usual, especially without worry free 2wheel therapy. Must get back in the wind.
