When I had the Wing out a couple days ago, it ran fine. I did notice that it seemed to use a bit more gas than I expected it to, but that's not the problem in of itself now.
I got on to take it for a state inspection and it wasn't running right. It acted like it wasn't hitting on all 4 cylinders. It broke up under load heading to the shop and I could smell gas. No leaks externally. Then, it just coughed up a lung and wouldn't restart. It did finally start, but I had used quite a bit of gas in the process and not over a great distance when all was said and done. I pulled the plugs as the shop where I got it inspected was next door to my Auto Zone. The right bank plugs were a bit carboned, but not completely black. The left not as much even. I still put in a set of fresh NGK plugs and it fired right up, but after a minute or so, was obviously not running well still. There's spark at all 4 wires. I did check that. I decided just to head for home while the getting was good, but had to make one stop.
I had to stop to get a prescription and had one helluva time getting it to restart. I did stop and refuel and put Seafoam in the gas. The bike was back on the road, but bogging and breaking up. When I got home, I couldn't make it up my driveway (inclined up). After some manual horsepower from the rear helping and having to restart it a couple times, I made it up and parked it totally disgusted.

It also started doing what it did when I bought it...higher than normal idle on the sidestand getting higher when standing up straight. I had tightened down every screw on all the carbs thinking that it was sucking air and it worked as it's first voyage out, it idled and ran just fine.
Fellas....I could sure use some insight. This engine layout is pretty new to me and it hasn't unlocked all of it's quirks yet. I also cannot afford hundreds on taking it to a shop right now, but I'd sure love to be able to have a few rides out of it before it has to go to bed for the winter.

It did pass inspection, though.
