So, not quite looking for answers yet but wanting to ask if I might be missing something off my list.
Just heading out today and the bike began stuttering, (I did hear a tick tick tick sound just as I was moving off, though it may been a stone stuck in the wheel.) About 500 yards down the road the divvy stutters as though short on fuel, switched to reserve and it felt as though it was taking ages to come through. Long story short it eventually cut out. Checked the tank and there was fuel in it. Started after a couple of attempts, (actually put it back to main tank just uncase ), and headed home. Within about 200yards from the driveway it died, tried on reserve (whislt coasting bump and on the starter) and nothing. Thankfully I live down hill from that junction
I've looked in the tank proper this time and there's definitely fuel in there, at least 2 litres, more than enough. Here what I'm thinking.
Blocked vacuum / breather (The bike ran and revved freely on the stand when I got it home, albeit after opening the fuel tank).
Blocked fuel filter / fuel line (Fuel filter was changed less than 1000 miles ago)
Badly adjusted carbs (had a beautiful 60 mile ride at sun down last night, all through the power band with no problems)
Carb diaphragm / vacuum - Hmm
Air filter (Unless I'd hoovered up four leaves I doubt I'd have a total failure).
Spark - Plugs, plug cables, CDI... (why would it fire fine at home - rev to 9k quite happily?)
Anyone got anything else I could be missing? I'm really short on time for the rest of the day, and tomorrow, so I'll do a pokey visual check first.
Cheers folks.
