Help please I have a situation:
cold engine runs well, but when get hot it begin to drang drang - and rpms goes up and down a bit:
I checked coils, changed water temp sensor, changed FI, changed spark plugs and nothing. ..
Finally started to test injector plugs (connectors) and found that hot engine runs the best way with cylinder 2 and 3 injectors unplugged. I cant believe that bike runs relatively smooth (on idle of course) only with injectors 1 and 4.
What is it? What to check?
