Some of you may remember my problems with Lori's lil Breva stumbling, losing power and surging. I replaced the computer, the tps and did the holy trinity of tps reset, balance and idle set, along with changing fuel filter, drilling out plugged drain hoses blah blah blah. Last week I was getting ready to winterize it perhaps to never take it out again. I rode it the 10 miles into town to fill up with non-ethanol gas and add some stabilizer and get it hot enough to change the oil. It was nearly unrideable. On the lift after the oil change, I was checking fuel lines. I had removed the right injector when I replaced the TPS and I noticed that the left one didn't look quite the same. I removed the screw which was terribly tight like there was pressure pushing up on the screw as I removed it. There is a boot at the end of the fuel line that the injector sits in sealed with an O ring around the injector. When the screw came out the injector popped out the the boot and fuel emptied out of the the line. This didn't happen on the right injector. It seems as though the O ring was not seated in the boot as deeply as the other. I reseated it by pushing it into the boot quite hard, put it back together and took it out for a 25 mile spin. It ran like it never has before. As smooth as my Norge. No vibration. No hiccups. No surge. Lori took it out for another 25 mile run yesterday. Ran like a dream. Could air have been sucked into the injector if it was not seated properly in the boot at the fuel supply end? It has run ok before and then started giving problems again, but it has never run this well and considering it was all but unrideable only an hour or two before the first good run, I'm optimistic. Thoughts?
