Starting to get a worrying fault - occasionally the falco coughs and surges as if going onto reserve, random sorts of times, either under load or on a steady throttle on the motorway. Thought it might be water or dirt in the petrol, but that's a couple of tankfuls now and still there.

If it had carbs I'd whip the float bowls off, or even just undo a drain plug - any advice on simple things to try? Assuming it's as straight-forward as just dirty fuel.....

Other than that, all well in falco-land, slightly dodgy indicator flasher unit aside.....btw, didn't mention that I finally fitted the correct and expensive new battery and started first prod - after 5 months sitting in the garage - very impressive!

I had a similar thing when I first got mine, mainly when rolling on from a closed throttle. Occasionally I'd get 'EFI' flashing up on the dash too.

Found it was the fuel cap drain blocked where it exits the tank at the bottom, fixed by removing the fitting, unblocking it and drilling it out to a larger size to stop it getting blocked again.

ahem, turned out to be a slighly loose lead on the battery terminal......ooops!

Nah - that's good news - you've found the cause and it's an easy and cheap fix.
