New (to me) ZX12R... issues
Well, I guess my 3rd Kawasaki makes me a devotee.I just love these big Kaws.
So, I just picked up a ZX12r, with issues. I am hoping you guys might be able to give me some advice. Here's the deal, 2002, 19k miles, looks very well taken care of. I got the bike cheap. The PO stated it has possible engine issues.
I will spare you all the detail, but basically he got an oil light. Pulled over, shut down and took the bike home via trailer. He said the engine was making some noises. Not a knock but not the ordinary smooth running sound. Said it seemed to be coming from the top end, but he was not sure. He says he dropped the pan, and found no metal whatsoever, and checked the filter with the same results.
So, I have taken the plastics off and here is what I found.
-Mild oil leak from valve cover gasket. This seems normal for the 12r
-Big hit on the oil pan/nut (it is a low bike and there's a lowering link in back). Couple of cooling fins in front of the nut removed, nut slightly bent (speed bump?)
-Mild leak from pan (possibly from PO dropping it and not replacing gasket?)
-Headers not attached properly (have to remove these to drop the pan, PO didn't tighten everything back?)
I removed the oil to double check and found no metal (except a couple of threads from around the bent nut, I am sure the are from the pan threading).
After filtering and replacing the oil, I started the bike and ran it from maybe 8 -10 seconds. Honestly, it seemed normal to me (other than like it had not run in a while), and sounded a lot like my GPZ1100e. The idle was very rough, but since the headers are not on right (I can hear it firing out the front), I think that probably has something to do with it. BUT, there was nothing that was totally obvious to me that sounded wrong. The oil light stayed on the whole time.
I am just wondering where to go next? Shall I inspect the oil pump? I want to run the bike, but I also do not want to damage anything. If the pan and filter and pump are clean, is it okay to run?
Thanks for any advice.
