So this is the second time I've filled up my bike since i got it and both times I put as much fuel in as I could. Now I didn't go up to the neck but pretty darn close and the bike started hard. I have a charcoal canister. Anyone else have this problem? What's actually going on here?
Hard starting after refuel.

Some seem fine, but it is a know problem on some bikes.
Mibanez3 on here had problems with his, to Quote
"They told me they had to reset the ECU.. Before they picked it up I checked all the fuses and disconnected the battery for 10 minutes with no success. What i understood the service rep when he brought it back was that the gas tank has some sort of canister (to meet polution requirements) to remove the fumes and it was creating too much vacuum. So they removed the canister and plugged the line that led to the canister.he told me that it happens often on the panigales.

I'm 30 pages into the owners manual and there have been half dozen warnings about over-filling the tank and associated hard-starting/rough idle/backfires. They specifically warn against filling into neck and supply a diagram of the charcoal emissions system. I guess we're learning what "over-full" is.
Yeah they warn about not filling up into the neck but seriously, I'm at least a half inch to an inch from the fuel reaching into the neck. I may have to ditch the canister after all...

This might help...
removing-evaporative-emissions-canister
granted its from the old air cooled bikes but the same principals should apply.

Just refueled for the third time today filling up as far as I dare but no hard starting this time. Weird.
Haven't seen my bike yet... Hoping by June. Slow boat to Hawaii. Wondering if you could add a hose extension to the charcoal canister that has a high loop in it so fuel doesn't get into it. I guess the loop would have to be pretty high. Or could you put a stop **** on yhe line to activate or not? Sorry if not accurate... Haven't seen this canister system in person. But my boat has a fuel vapor vent hose that has a high bend to prevent water from getting in the fuel.

The fun part on ours is getting to the vac hose on the vertical cylinder throttle body. Going to need some long needle nose pliers to reach through the frame.

So are the problems, cause by filling up the tank too mutch, disappear without action, as soon as the tank gets empty?

Welp, took my bike in for 600 mile service. Little over 200 mile drive oneway for me, or about $100 fuel. 
The tech asked if it would be alright to remove the carbon canister? I said it had not given me any problems but if he wanted to remove it . . . . So when I come back to get the bike my stuff is in a big ziplock bag. LOL
Oh, for you guys going for 600 mile service, put 624 or more miles on, as 600 or less than 624 will not trip the "Oil Service" warning. I rode mine around till I got 624 and brought it back, and the tech reset with computer.
