I would certainly check the condition of the plugs. That will be a start in diagnosing the air to fuel ratio. Clean all ground wires, check condition of plug wires. You can test the ignition coil with a meter. Open the air box and check the air filter. Replace paper filter with a high flow air filter or if you already have one, clean it. If you see the inner air box has a Swiss cheese mod or air box elimation mod, you may have a lean running bike (the color of your plugs, when you check them, will also give insight into a lean condition.) If you do have an altered inner air box and/or open exhaust, I suggest downloading a race map that has a richer fuel value. Do an intake leak test. Since you have the air box off, do a breather reroute (many threads/videos for this DIY.) This will keep the crankcase vapors from contaminating your air filter. You can ride it in "closed loop" parameters to "relearn," but I believe that year ecm isn't as adaptive as the later models. Ecmspy is available in English I ordered my cable and software from Ebay. Maps can be found on buellmods.com If I left something out it's because it's 12:30am and I just left my shop from installing a Barnett steel braided clutch cable on my 'bolt (adjusted the primary chain, primary clutch and cable, primary oil.) I'm considering a 200 mile ride by myself tomorrow to go catch up to a buddy who left today. So, I needed to get her ready. I think I got her dialed in. Clutch feels very responsive. PS-I hope you have some time set aside this weekend to get it running right so you can get on the road and carve the pavement GL
