The problem with prefilling a VN750 oil filter is that you can only get a little bit in it, because it is horizontal. If it were vertical you could fill it completely up. But I have changed the oil in 2 different VN750s every 3000 miles for close to 200,000 miles, and never poured oil into the filter, with no problems. Oil light went out within 2 seconds.

There is another issue with some Kawasaki engines however. I don't know if it affects the VN750, because I have never dropped one. It affects the engines in the 454LTD, both versions of the VN500, and the EX500. I used to own a 2009 EX500 Ninja, and joined a Ninja 500 forum. A few members there wound up destroying their engines, because they dropped their bikes, picked them up, started them, and took off, not noticing the oil pressure light was still on. Apparently there is a design issue with these engines that causes the pump to lose prime if the bike is laid on it's side. Not a problem if the oil is drained and refilled with the bike upright. Since this happened to 5 -6 members of one forum, there is definitely a problem with that particular engine.

I am a motorcyclist, NOT a biker.
