I know everyone will roll their eyes at another of these questions, but I'm asking anyway. So when I bought my 1100ex it was already converted to pods and a winning performance 4 into 1. The guy I bought it from was of course selling it for somebody else. He said that it was dynoed blah blah blah. I thought it was the bees knees as far as performance goes, because it is by far the fastest bike I have ever owned. I was still having lean issues according to the plugs but they weren't fouling. I did find some exhaust leaks and leaks in the intake boots so I replaced them. I took the packing out of the baffle to get more volume from the exhaust. It's still not loud enough, but at least I can hear the bike. WOW, could I hear how bad the tuning was. What was at one time a slight gargle with a few puhs on deceleration, was now loud with severe backfiring. First thing I noticed is the idle screws were filled in with some sort of rubber cement type glue. I scraped that out and managed to get it a little better with a few turns out on the idle mixture screw. I made a bracket for the carbs so they weren't hanging by the boots which helped with steady idle and performance more than I would have thought. I'm actually surprised I haven't seen that mentioned on the forums. The top end seemed to run great all the problems were in the idle off idle area so I went into the carbs to figure out what it was jetted to and what to get. I was thinking I would need a dyno stage 3, but after seeing the 138 main jet and the fact that the top end was the strongest part of the throttles powerband (hitting 5000-6000 RPMs felt like some sort of over drive,) I concluded that a dyno 3 was already installed. The pilots were still 45s and I had them about 4-5 turns out so I knew to go bigger. Plus the the LOUD gargling and popping on decel. I put in 47.5s still at 4+ turns out, more bottom end power, but the gargling and pops were less loud, but definitely still there. Time to go up again. 50's on the pilot color tuned to 3 turns out, and even more bottom end with an incredibly smooth power band, and the gurgling stopped on decel. It seems to run great, but when I engine brake I'm still getting gurgling and some popping. (It idles strong, I can get into first and cruise along without touching the throttle on a flat to slight incline at 1000rpm idle.) I was thinking of going up to a 52.5 on the pilot, but I haven't heard of anyone else going that big. I guess my question is, should I look for another problem or is it possible I need a pilot jet that big? Or should I just say screw it the bike will gurgle and pop on heavy decel/ engine braking?
