So I purchased a brand new 2013 N1k. At 450mi I did my first oil change. Just like on any other bike i've owned - I opened the oil fill cap, removed drainplug, removed filter and let out for several minutes. Installed new filter - re tightened drain plug, filled with oil and re installed fill cap. When I started it - oil pressure light stayed on. I let it idle for a good 20 seconds In hopes of oil pressure being achieved after new oil filter is has filled - LIGHT STILL ON. I killed it to prevent any damage and let it sit for a few minutes. Started it again and let it idle - another 20 seconds still NO Oil Pressure!! On my third attempt, I started it with the Oil filter barely hand tight, cracked the oil filter loose with it running until a huge air pocket spewed out and oil then came fallowing - BOOM oil pressure achieved instantly after that.. I now have 950mi and changed the oil a second time - Everything I did the same except: when i filled with oil, i let the bike sit for 15min with no oil fill cap on to let all the oil run down - I then put the cap on and started it (with a dry oil filter) and oil pressure was achieved within 4-5 seconds.. Whats up with this oil pump air lock situation? Have any of you experienced it, if so what is your solution? HAS ANYONE DAMAGED THEIR ENGINE BECAUSE OF THIS?!
