HELP!! 04 1100 custom not firing on rear cylinder...
Guys I need help racking my brain here...I bought an 04 1100 Custom back in October that had been sitting for almost a year but had been started here and there. Bike rode great and all things considered ran pretty good, but had a little bit of a pop/back fire to it here and there. Rode it for several weeks trying SeaFoam and a couple other fuel system cleaners but nothing worked to get rid of it. Finally tore the carbs apart and cleaned them and found a good bit of gum built up in them. Put it back together and it fired up and ran and accelerated a lot smoother but still had the pop. Ended up being tight exhaust valve. Had everything back together and it was running amazing!! Right up until it went to crap...Took off from a stop sign on a straight away and wound out 1st and 2nd pretty good when I shifted into 3rd I lost most of my power just like if I needed to flip over to reserve,but after I did I never regained power. After stopping and looking I still had plenty of gas. There were no noises or catastrophic mechanical problems. It was firing on the front cylinder but losing the rear cylinder when you revved past an idle...checked some things and tested some things and had all intention of upgrading the ignition system anyway so I decided this was a good time to do so...so since then I have put on Dynatek 3000 ignition and coils, new regulator/rectifier, new stator/pickup coil, and new Iridium plugs. I put them on one piece at a time trying to determine what the original problem was, but even after all of that it is still not firing properly on the rear cylinder. With a timing light inductive lead on the front plug wire it fires steady and regular, the rear cylinder is very erratic and all over the place. Is there anything else on these bikes that controls ignition that I might be missing?
