04 Vulcan 1600 Mean Streak
Hi everyone... just picked up a Mean Streak and am having some issues.
Quick summary before the story, My FI light is going on and off when I twist the throttle, bike runs like $hit.
Got the bike on Tuesday, ran beautifully, lots of torque and power... well at least compared to the other V-twins I ride.
I rode around all day wednesday without as much as a problem, passed inspection and I must have put on 100 miles in between going to work.
Thursday morning everything is running fine until lunch time when I take her out for a little ride and it seems like I am missing a cylinder... FI light pops on and she is running like $hit.
The investigation begins with a new tank of gas... didn't get to drain the other, but figured I could put in some injector cleaner/water remover to help out. I drive the lady home and the new gas is no help yet. I pull off the side panel and low and behold there is a power commander sitting there (doubt the guy before me knew it was even there, all work was done without question from the dealer)... I hook up to it and it read stock everything for this bike. Popped out the plugs and both of the back cylinder plugs are fouled, front look fine. So I clean up the back and switch them, front to back. Start her up and still runs like dog dump.
My plan is to replace the plugs and try her again... I also noticed there are aftermarket NGK spark plug wires, and the plugs were NGKs.
Does anyone have any other ideas? My next move is to uninstall the power commander and see how she runs.
Thank you very much for the help.
