Troubleshooting ideas: surging/cyclic cutout at ~2750 RPM in only 6th gear
Lookin for ideas as to where to troubleshoot this problem. Right now, my plan is to check the ignition system, and the fuel map for obvious problems. Have aftermarket (Accel) wires and a set of stock plugs I can swap out. Haven't pulled the plugs yet so dont know their condition. This issue came up only yesterday.
Accel plug wires
dynojet PCV with autotune set to 13.7-13 AFR depending on cell
Lloydz/S&S airbox + IAV
RPW Thor with homemade restrictor/baffle
When upshifting into 6th gear to cruise at about 2750 RPM using 20-30% throttle (per the PCV software when I got home), the bike went into a rapid surge<-->misfire condition that I could only cure by downshifting to fifth. When I shifted back to sixth it seemed to go away. Then no more than five to ten minutes later, after an overtake manuever, upshifted back to sixth to cruise and the same thing happened. The misfire is pretty violent and the cycle time between surge-misfire is around half a second.
I'm going to look at the fuel map for oddities that may be causing this, along with electrical connectors, and the aforementioned ignition system. Any other suggestions?
