Thanks - I'll start with the standard settings then and work from there.
And a couple of last stupid questions (they're back up on the bike, I'll stop soon, I promise!)
- How do you all route your fuel lines? To me it looks like there are two holes in the mounting plate perfectly positioned for the lines to go through and then run across the top of the inlet rubbers before linking up. Only other way I can see is to loop round underneath the carbs, or go round the end of the carbs and then underneath one inlet rubber to come up and join the fuel tap (as mine was, and it looked ugly). Main problem is that I can't find any pictures of existing setups.
- The carb rebuild kits I got (I'm not using the jets, just the needle, gaskets and float assemblies) contained a small rubber o-ring which I can't identify and I definitely haven't removed any similar ones from the carbs. Anyone hazard a guess as to where it should locate? Did wonder if it was related to the air mixture screw, but I'm not sure how that'd work, or ever be retrievable.
