Bonneville America Forums Forums Technical Forums General Tech Stalling BA - Touring Bruge tomorrow (or not)

Hey all! I might (I hope) be coming to the ends of my trials and tribulations with my America. However, my latest exciting issue is that for no reason at all it will randomly lose drive power (not electrical power) and then stall (after running fine for a chunk of miles and varying speeds). Sometimes it stalls at 30mph, sometimes at 75mph (exciting).

usually i've changed from res to main, or main to reserve and after about 30 seconds or so it starts up fine (or roughly and then it evens out).

I just want to check if, in your opinion, any of these could be causing a stall :

1) The Pilot screw being at the wrong setting (My carbs came from a bored out Speedy, It's clean, has stock needles and no shims but i didn't check the pilot screw).

2) The inline fuel filter being fixed on the wrong way round (i.e. the arrow pointing the opposite way to how it should be).


I've :
Checked the tank vent/tip over thing (clean)
Whacked in a new petcock and screen (even though the old one was clean)
Removed the hidden filter thingy
Emptied some more of the tank just in case there's rubbish in there (there wasn't much)
Made sure there's no kinks in the line from petcock to carbs.
Carbs are clean
Put the inline filter the right way around.

Anything else you chaps can think of? going to take it for a run in a bit but i'm meant to be riding to Bruge and Amsterdam tomorrow...but as you can imagine It might not be happening if i can't trust it in the fast lane of a motorway.

Intermittent ignition failure? Sounds as if you have eliminated all the usual fuel suspects, electric glitches are the worst, especially when not constant and hard to diagnose. I feel for you.

Follow the Arrow, huh?

Dropped it into my local mechanic as i'd done everything I could think of with it.

Turns out that while the tank breather hose was okay, the actual line _inside_ the tank had gotten slightly blocked up (probably when it was chemically stripped) and it's run a few miles since without stalling so hopefully that's sorted it.

Inline filter being the right way round didn't seem to affect anything performance wise so I assume it's either bust (from me running it the wrong way) or doesn't matter. The arrow on it was barely visible (white on white) so I couldn't see it the first few times i looked.

Fingers crossed that's sorted it (though last time it was a full 13 miles before it stalled). I suspect i'll need to think about swapping my Aero style cap with a vented equivalent at some point.
