Tuning Question, Need help
Recently I experienced loss of spark to the rear cylinder. After spending quite a bit of time going thru the process of elimination, (Spark plug, Coil. Connector plug and doing some continuity testing thinking maybe I fault in the wire harness). After every thing checked out, I had decided to remove the Power commander V and plug into the ECM directly to see if it had spark to the rear cylinder. Yes it did !!!
I re-installed Spark plug and Coil, and it fired right off and purred like a happy kitten. Now I have some new questions. Previous owner of this bike before me had installed a Vance Hines 2 into 1 Comp pipe and had eliminated the Oxygen sensors. I bought it off a Trader in Albuquerque, NM w/ 1700 miles on it for $9,500. Never had any problems until this go-around. How will this bike run without the Oxy sensors and no PC V. Can I hurt the motor ? Thanks for any help , DJ Tanner
