It's a two fold question. Rode my 07 SG home from work a couple days ago, when I tried to go for an evening scoot she wouldn't start, turned over fine but not start, I checked spark, did a little research and thought I had a relay issue. Raised bike of a lift Swapped Brake Light relay for starter relay and still no luck, security lights started flashing constant, I replaced fob batt and got those to stop. Now I get nothing at all when I hit the start switch. Battery has been kept charged, I've load tested it and it seems fine. I replaced two relays, checked power to starter itself.....one thing is I get no juice to the small black wire @ starter which I was expecting when I used a test light and hit the starter switch....no the kill switch is not on, I've tightened the starter bolts themselves for better ground contact...... Any suggestions?? Second part, I unplugged after market tuner to go back to normal and I cannot for the life of me get the O2 sensors reconnected / plugged back together. Is there some trick to these?
