I just changed the oil again to make sure all the fuel was out of there (after the dreaded fuel running into the crankcase last fall) and wanted to fire her up after doing so. She's running like pure garbage again, spitting and backfiring at low rpm, only cleans out up top.
I have had these carbs off a dozen times, the needle and seats are new, floats adjusted perfectly, the carbs were tuned with my Colortune, then synced. The rubber plugs inside are new, as are the float bowl gaskets. The mixture screws are all brand new. You could eat off of the carbs they are so clean. The plugs are brand new, I repaired the broken wires at the pickup coil - everything.
I had the bike running absolutely perfectly last summer. She'd start up and purr like a kitten, and when I took her out on the road I was grinning ear to ear as she was faster than I could have ever dreamed. When I'd pull up to a stop sign she'd quietly purr, and it was pure bliss.
That lasted all of a few days apparently, because she's one GROUCHY old gal, now. Just running miserably. I am at my wit's end. What am I missing here? I see nothing visibly wrong in the carbs.
