Draining fuel

Short of removing the fuel tank, is there any way to drain the fuel from the tank. This is the first spring my '13HS has not fired right up with a freshly charged battery.

I'm wondering if the gas in the tank(probably less than a couple of liters)which I treated last fall is preventing the old girl from firing. I've added a gallon of fresh non-ethanol premium but that hasn't helped. It turns over but doesn't seem to fire. Battery is fully charged and the ground connection has been cleaned up. It will fire a couple of times but won't continue.

Suggestions?

Colin

Ended up removing the tank to check spark plugs. They were looking pretty wet and fouled so am replacing them as well as totally draining tank. New plugs arrive tomorrow so will try again with fresh gas and new plugs!

Still won't start

OK, new spark plugs, fresh gas, air filter looks good, turns over but doesn't seem to fire. I put replacement coils in 14 months ago(Aprilia ones) and it ran well last season.

Suggestions?

Spark plug wet and fouled - that seems the place to start. Wet with fuel? Wet with oil? Just guessing her - if wet with fuel then the injectors are injecting, but the plug isn't sparking. Can you test this?

All contacts in the circuit cleaned?

Would seem strange for 2 coils to go at once. What's upstream from the coils?

All fuses good?

Fuses look good. The plugs, which were replaced 8000km ago, were wet with oil and, I think, gas. I replaced the coils at the same time last year, being a bit paranoid about the dash failure thing. Also had the CAN filter thing done.

There was probably about 1 liter of gas in the tank when I put it to bed last fall and I wonder if I put too much fuel stabilizer in. This morning I did siphon out all the gas, including the 4 liters of premium non-ethanol stuff I'd put in a few weeks ago.

Not sure about testing for spark, I'm not really comfortable with seeing if the plug sparks to ground on the engine. The nearest Duc dealer is a 200 mile/4 hour drive so would like to solve this on my own if possible!

TIA

Is there more than 1 ground connection to the engine? I cleaned up the one that was obvious and that seemed to help the old girl turn over a bit better.

I'd like to be of more help but I can only offer helpful suggestions - something everyone loves.

I'd check the spark. If no spark then something up the line is affecting both plugs. The manual that comes with the bike has an electrical chart - I'd follow the circuits to a point where they converge and hopefully somewhere around there is the problem.

I'd also go over what you did when replacing the coils. Did you crimp new connectors etc? Maybe spray some contact cleaner in those connections after checking them with an ohm meter.

The good news- I always find that when the issue is so absolute the problem is easier to find and fix. If it started sometimes- or ran on one cylinder - then things get tricky.

Where are all those smart backyard mechanics? Is there a relay in the starting circuit i should be checking? Why are those coils not firing? I looked at the connections along the coil circuit and they look OK, no wires coming adrift.

There is a spark on the horizontal cylinder. The old girl cranks over well but just doesn't seem to fire.

I'm wondering if there is a fueling problem. Has anyone had a fuel pump failure? Is there a replaceable fuel filter somewhere on the fuel flange? I looked at the Ducati Omaha parts picture and they show only a "fuel flange" that lists for $1023US!
