So this issue has been going on ever since I had the bike, every time I go to fill up at a gas station, it seems to be very difficult to start the bike after. I'm trying to fill below the filler neck. It starts fine if I shut off/turn back on, just only after filling the tank it backfires and doesn't want to kick on right away. Right now I'm actually waiting for it to cool down some before trying to start it again... Any suggestions?

Here's the thing though, it's not hot starting that's the problem, I can start & restart no problem, it's only after filling up the tank that it doesn't feel like firing up. It cranks, does one pop, then just struggles to fire up.

Sounds just like mine if I open the throttle while cranking. I got in the habit of using the choke after fill ups, starts right up. If I don't use the choke, it just cranks and backfires.

the hot start issue shows itself most noticeably when shut down hot, 3-10 min wait (filling up), then try to restart.

mine did the exact same thing.. let it sit 10-15 mins (sometimes less) and it will fire right up.

pickup coil mod fixed it

I set my pickup coils to 0.018" and just barely crack the throttle when cranking and it starts hot perfect every time.

I've heard of pickup coil mod but I'm honestly not exactly understanding it. I know you're supposed to trim something & set another thing to 0.020", but what exactly does this mean? What is this the distance between?

Also should point out a weak battery can cause starting problems too...switching from the wet cell that comes with the bike to a good AGM battery cured my starting issues...(which were only noticed after filling up or stopping a short time). I doubt your issue is related to the gas tank..

Iridium spark plugs and/or K&N drop-in air filter replacement fixed mine. Not sure which one or both are needed since I did both upgrades at the same time. Problem went away immediately and now going on 8 years since with no problems. Added a little extra overall performance as well. Plus, easy upgrade.

I did replace the spark plugs, it didn't help much. I tried starting it with the fuel tank open, same scenario. Just had to let it chill a bit. I've ordered an AGM battery, and now planning to do the pickup mod some point this week, so let's see if that makes a difference of any sort....
One question, I know I might have to rotate the motor to get the plate next to the coils, which way should I rotate? Clockwise or counter? Also, should the bike be cold for this or is warm fine?

Probably one of the easiest to do and I did notice a difference. Also clean the ignition switch if you haven't already.

Well, after weeks of being stubborn I finally gave in & did the pickup mod. It starts without problems after getting gas now, & starts easier in all cases. Why the issue only presented itself after getting fuel I have no idea, but, I guess we're all good for now...
