Did I ruined my 12R by running with no oil pressure?
So I have this perfect black 2004 zx-12r . One day I completely drained the oil. Added new oil and changed oil filter. Then when I ran the bike, there was no oil pressure. I was stupid enough to keep it running for about 10mins and revved thinking it will establish pressure. STUPID~! Then I read online you will have to open the filter just a little to let air out....
Anyways.. then oil pressure came back. Bike ran normal. I went out and did 140mph. Then I parked the bike for a year. This summer, when I ran it, I felt the idle became a little rough. It surges a little. Not too much though.
Is it because of spark plugs (I have never changed it), or fuel system clogged?
It's not burning oil, that's for sure.
If there were damages due to last oil change incident, will the idle be rough? It sounds ok when revved up....
